|
||||
// Implemented features:
|
||||
// [X] Renderer: User texture binding. Use 'ALLEGRO_BITMAP*' as ImTextureID. Read the FAQ about ImTextureID!
|
||||
// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy ALLEGRO_KEY_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
|
||||
// [X] Platform: Clipboard support (from Allegro 5.1.12)
|
||||
// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
|
||||
// Issues:
|
||||
// [ ] Renderer: The renderer is suboptimal as we need to convert vertices manually.
|
||||
// [ ] Platform: Missing gamepad support.
|
||||
|
||||
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
||||
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
|
||||
// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
|
||||
// Read online: https://github.com/ocornut/imgui/tree/master/docs
|
||||
|
||||
// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2022-11-30: Renderer: Restoring using al_draw_indexed_prim() when Allegro version is >= 5.2.5.
|
||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
||||
// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
|
||||
// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
|
||||
// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
|
||||
// 2022-01-17: Inputs: always calling io.AddKeyModsEvent() next and before key event (not in NewFrame) to fix input queue with very low framerates.
|
||||
// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
|
||||
// 2021-12-08: Renderer: Fixed mishandling of the the ImDrawCmd::IdxOffset field! This is an old bug but it never had an effect until some internal rendering changes in 1.86.
|
||||
// 2021-08-17: Calling io.AddFocusEvent() on ALLEGRO_EVENT_DISPLAY_SWITCH_OUT/ALLEGRO_EVENT_DISPLAY_SWITCH_IN events.
|
||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2021-05-19: Renderer: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
||||
// 2021-02-18: Change blending equation to preserve alpha in output buffer.
|
||||
// 2020-08-10: Inputs: Fixed horizontal mouse wheel direction.
|
||||
// 2019-12-05: Inputs: Added support for ImGuiMouseCursor_NotAllowed mouse cursor.
|
||||
// 2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
|
||||
// 2019-05-11: Inputs: Don't filter character value from ALLEGRO_EVENT_KEY_CHAR before calling AddInputCharacter().
|
||||
// 2019-04-30: Renderer: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
||||
// 2018-11-30: Platform: Added touchscreen support.
|
||||
// 2018-11-30: Misc: Setting up io.BackendPlatformName/io.BackendRendererName so they can be displayed in the About Window.
|
||||
// 2018-06-13: Platform: Added clipboard support (from Allegro 5.1.12).
|
||||
// 2018-06-13: Renderer: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
|
||||
// 2018-06-13: Renderer: Stopped using al_draw_indexed_prim() as it is buggy in Allegro's DX9 backend.
|
||||
// 2018-06-13: Renderer: Backup/restore transform and clipping rectangle.
|
||||
// 2018-06-11: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
|
||||
// 2018-04-18: Misc: Renamed file from imgui_impl_a5.cpp to imgui_impl_allegro5.cpp.
|
||||
// 2018-04-18: Misc: Added support for 32-bit vertex indices to avoid conversion at runtime. Added imconfig_allegro5.h to enforce 32-bit indices when included from imgui.h.
|
||||
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplAllegro5_RenderDrawData() in the .h file so you can call it yourself.
|
||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
|
||||
// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.

// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.

// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy AKEYCODE_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]

// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen.
|

// Missing features:
|

// [ ] Platform: Clipboard support.
|
||||
// [ ] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
|
||||
// [ ] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'. FIXME: Check if this is even possible with Android.
|
||||
// Important:
|
||||
// - Consider using SDL or GLFW backend on Android, which will be more full-featured than this.
|
||||
// - FIXME: On-screen keyboard currently needs to be enabled by the application (see examples/ and issue #3446)

|

// (minor and older changes stripped away, please see git history for details)
|
||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2021-05-19: DirectX10: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
||||
// 2021-02-18: DirectX10: Change blending equation to preserve alpha in output buffer.
|
||||
// 2019-07-21: DirectX10: Backup, clear and restore Geometry Shader is any is bound when calling ImGui_ImplDX10_RenderDrawData().
|
||||
// 2019-05-29: DirectX10: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|
||||
// 2019-04-30: DirectX10: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
||||
// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
|
||||
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
|
||||
// 2018-07-13: DirectX10: Fixed unreleased resources in Init and Shutdown functions.
|
||||
// 2018-06-08: Misc: Extracted imgui_impl_dx10.cpp/.h away from the old combined DX10+Win32 example.
|
||||
// 2018-06-08: DirectX10: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
|
||||
// 2018-04-09: Misc: Fixed erroneous call to io.Fonts->ClearInputData() + ClearTexData() that was left in DX10 example but removed in 1.47 (Nov 2015) on other backends.
|
||||
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX10_RenderDrawData() in the .h file so you can call it yourself.
|
||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
|
||||
// 2016-05-07: DirectX10: Disabling depth-write.

// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2021-05-19: DirectX11: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
||||
// 2021-02-18: DirectX11: Change blending equation to preserve alpha in output buffer.
|
||||
// 2019-08-01: DirectX11: Fixed code querying the Geometry Shader state (would generally error with Debug layer enabled).
|
||||
// 2019-07-21: DirectX11: Backup, clear and restore Geometry Shader is any is bound when calling ImGui_ImplDX10_RenderDrawData. Clearing Hull/Domain/Compute shaders without backup/restore.
|
||||
// 2019-05-29: DirectX11: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|
||||
// 2019-04-30: DirectX11: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
||||
// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
|
||||
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
|
||||
// 2018-08-01: DirectX11: Querying for IDXGIFactory instead of IDXGIFactory1 to increase compatibility.
|
||||
// 2018-07-13: DirectX11: Fixed unreleased resources in Init and Shutdown functions.
|
||||
// 2018-06-08: Misc: Extracted imgui_impl_dx11.cpp/.h away from the old combined DX11+Win32 example.
|
||||
// 2018-06-08: DirectX11: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
|
||||
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX11_RenderDrawData() in the .h file so you can call it yourself.
|
||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
|
||||
// 2016-05-07: DirectX11: Disabling depth-write.

|

// Implemented features:
|

// [X] Renderer: User texture binding. Use 'ID3D11ShaderResourceView*' as ImTextureID. Read the FAQ about ImTextureID!
|

// [X] Renderer: Large meshes support (64k+ vertices) with 16-bit indices.

// dear imgui: Renderer Backend for DirectX12
|
||||
// This needs to be used along with a Platform Backend (e.g. Win32)
|
||||
|
||||
// Implemented features:
|
||||
// [X] Renderer: User texture binding. Use 'D3D12_GPU_DESCRIPTOR_HANDLE' as ImTextureID. Read the FAQ about ImTextureID!
|
||||
// [X] Renderer: Large meshes support (64k+ vertices) with 16-bit indices.
|
||||
|
||||
// Important: to compile on 32-bit systems, this backend requires code to be compiled with '#define ImTextureID ImU64'.
|
||||
// This is because we need ImTextureID to carry a 64-bit value and by default ImTextureID is defined as void*.
|
||||
// To build this on 32-bit systems:
|
||||
// - [Solution 1] IDE/msbuild: in "Properties/C++/Preprocessor Definitions" add 'ImTextureID=ImU64' (this is what we do in the 'example_win32_direct12/example_win32_direct12.vcxproj' project file)
|
||||
// - [Solution 2] IDE/msbuild: in "Properties/C++/Preprocessor Definitions" add 'IMGUI_USER_CONFIG="my_imgui_config.h"' and inside 'my_imgui_config.h' add '#define ImTextureID ImU64' and as many other options as you like.
|
||||
// - [Solution 3] IDE/msbuild: edit imconfig.h and add '#define ImTextureID ImU64' (prefer solution 2 to create your own config file!)
|
||||
// - [Solution 4] command-line: add '/D ImTextureID=ImU64' to your cl.exe command-line (this is what we do in the example_win32_direct12/build_win32.bat file)
|
||||
|
||||
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
||||
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
|
||||
// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
|
||||
// Read online: https://github.com/ocornut/imgui/tree/master/docs
|
||||
|
||||
// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2021-05-19: DirectX12: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
||||
// 2021-02-18: DirectX12: Change blending equation to preserve alpha in output buffer.
|
||||
// 2021-01-11: DirectX12: Improve Windows 7 compatibility (for D3D12On7) by loading d3d12.dll dynamically.
|
||||
// 2020-09-16: DirectX12: Avoid rendering calls with zero-sized scissor rectangle since it generates a validation layer warning.
|
||||
// 2020-09-08: DirectX12: Clarified support for building on 32-bit systems by redefining ImTextureID.
|
||||
// 2019-10-18: DirectX12: *BREAKING CHANGE* Added extra ID3D12DescriptorHeap parameter to ImGui_ImplDX12_Init() function.
|
||||
// 2019-05-29: DirectX12: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|
||||
// 2019-04-30: DirectX12: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
||||
// 2019-03-29: Misc: Various minor tidying up.
|
||||
// 2018-12-03: Misc: Added #pragma comment statement to automatically link with d3dcompiler.lib when using D3DCompile().
|
||||
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
|
||||
// 2018-06-12: DirectX12: Moved the ID3D12GraphicsCommandList* parameter from NewFrame() to RenderDrawData().
|
||||
// 2018-06-08: Misc: Extracted imgui_impl_dx12.cpp/.h away from the old combined DX12+Win32 example.
|
||||
// 2018-06-08: DirectX12: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle (to ease support for future multi-viewport).
|
||||
// 2018-02-22: Merged into master with all Win32 code synchronized to other examples.

// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2021-06-25: DirectX9: Explicitly disable texture state stages after >= 1.
|
||||
// 2021-05-19: DirectX9: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
||||
// 2021-04-23: DirectX9: Explicitly setting up more graphics states to increase compatibility with unusual non-default states.
|
||||
// 2021-03-18: DirectX9: Calling IDirect3DStateBlock9::Capture() after CreateStateBlock() as a workaround for state restoring issues (see #3857).
|
||||
// 2021-03-03: DirectX9: Added support for IMGUI_USE_BGRA_PACKED_COLOR in user's imconfig file.
|
||||
// 2021-02-18: DirectX9: Change blending equation to preserve alpha in output buffer.
|
||||
// 2019-05-29: DirectX9: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|
||||
// 2019-04-30: DirectX9: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
||||
// 2019-03-29: Misc: Fixed erroneous assert in ImGui_ImplDX9_InvalidateDeviceObjects().
|
||||
// 2019-01-16: Misc: Disabled fog before drawing UI's. Fixes issue #2288.
|
||||
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
|
||||
// 2018-06-08: Misc: Extracted imgui_impl_dx9.cpp/.h away from the old combined DX9+Win32 example.
|
||||
// 2018-06-08: DirectX9: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
|
||||
// 2018-05-07: Render: Saving/restoring Transform because they don't seem to be included in the StateBlock. Setting shading mode to Gouraud.
|
||||
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplDX9_RenderDrawData() in the .h file so you can call it yourself.
|
||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.

// (Requires: GLFW 3.1+. Prefer GLFW 3.3+ or GLFW 3.4+ for full feature support.)
|

// [X] Platform: Clipboard support.
|
||||
// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen (Windows only).
|
||||
// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy GLFW_KEY_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]

// [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
|

// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2023-06-12: Accept glfwGetTime() not returning a monotonically increasing value. This seems to happens on some Windows setup when peripherals disconnect, and is likely to also happen on browser + Emscripten. (#6491)
|
||||
// 2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen/ImGuiMouseSource_Pen on Windows ONLY, using a custom WndProc hook. (#2702)
|
||||
// 2023-03-16: Inputs: Fixed key modifiers handling on secondary viewports (docking branch). Broken on 2023/01/04. (#6248, #6034)
|
||||
// 2023-03-14: Emscripten: Avoid using glfwGetError() and glfwGetGamepadState() which are not correctly implemented in Emscripten emulation. (#6240)
|
||||
// 2023-02-03: Emscripten: Registering custom low-level mouse wheel handler to get more accurate scrolling impulses on Emscripten. (#4019, #6096)
|
||||
// 2023-01-04: Inputs: Fixed mods state on Linux when using Alt-GR text input (e.g. German keyboard layout), could lead to broken text input. Revert a 2022/01/17 change were we resumed using mods provided by GLFW, turns out they were faulty.
|
||||
// 2022-11-22: Perform a dummy glfwGetError() read to cancel missing names with glfwGetKeyName(). (#5908)
|
||||
// 2022-10-18: Perform a dummy glfwGetError() read to cancel missing mouse cursors errors. Using GLFW_VERSION_COMBINED directly. (#5785)
|
||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
||||
// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
|
||||
// 2022-09-01: Inputs: Honor GLFW_CURSOR_DISABLED by not setting mouse position.
|
||||
// 2022-04-30: Inputs: Fixed ImGui_ImplGlfw_TranslateUntranslatedKey() for lower case letters on OSX.
|
||||
// 2022-03-23: Inputs: Fixed a regression in 1.87 which resulted in keyboard modifiers events being reported incorrectly on Linux/X11.
|
||||
// 2022-02-07: Added ImGui_ImplGlfw_InstallCallbacks()/ImGui_ImplGlfw_RestoreCallbacks() helpers to facilitate user installing callbacks after initializing backend.
|
||||
// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
|
||||
// 2021-01-20: Inputs: calling new io.AddKeyAnalogEvent() for gamepad support, instead of writing directly to io.NavInputs[].
|
||||
// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
|
||||
// 2022-01-17: Inputs: always update key mods next and before key event (not in NewFrame) to fix input queue with very low framerates.
|
||||
// 2022-01-12: *BREAKING CHANGE*: Now using glfwSetCursorPosCallback(). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetCursorPosCallback() and forward it to the backend via ImGui_ImplGlfw_CursorPosCallback().
|
||||
// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
|
||||
// 2022-01-05: Inputs: Converting GLFW untranslated keycodes back to translated keycodes (in the ImGui_ImplGlfw_KeyCallback() function) in order to match the behavior of every other backend, and facilitate the use of GLFW with lettered-shortcuts API.
|
||||
// 2021-08-17: *BREAKING CHANGE*: Now using glfwSetWindowFocusCallback() to calling io.AddFocusEvent(). If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetWindowFocusCallback() and forward it to the backend via ImGui_ImplGlfw_WindowFocusCallback().
|
||||
// 2021-07-29: *BREAKING CHANGE*: Now using glfwSetCursorEnterCallback(). MousePos is correctly reported when the host platform window is hovered but not focused. If you called ImGui_ImplGlfw_InitXXX() with install_callbacks = false, you MUST install glfwSetWindowFocusCallback() callback and forward it to the backend via ImGui_ImplGlfw_CursorEnterCallback().
|
||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2020-01-17: Inputs: Disable error callback while assigning mouse cursors because some X11 setup don't have them and it generates errors.
|
||||
// 2019-12-05: Inputs: Added support for new mouse cursors added in GLFW 3.4+ (resizing cursors, not allowed cursor).
|
||||
// 2019-10-18: Misc: Previously installed user callbacks are now restored on shutdown.
|
||||
// 2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
|
||||
// 2019-05-11: Inputs: Don't filter value from character callback before calling AddInputCharacter().
|
||||
// 2019-03-12: Misc: Preserve DisplayFramebufferScale when main window is minimized.
|
||||
// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
|
||||
// 2018-11-07: Inputs: When installing our GLFW callbacks, we save user's previously installed ones - if any - and chain call them.
|
||||
// 2018-08-01: Inputs: Workaround for Emscripten which doesn't seem to handle focus related calls.
|
||||
// 2018-06-29: Inputs: Added support for the ImGuiMouseCursor_Hand cursor.
|
||||
// 2018-06-08: Misc: Extracted imgui_impl_glfw.cpp/.h away from the old combined GLFW+OpenGL/Vulkan examples.
|
||||
// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
|
||||
// 2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value, passed to glfwSetCursor()).
|
||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
|
||||
// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
|
||||
// 2018-01-25: Inputs: Added gamepad support if ImGuiConfigFlags_NavEnableGamepad is set.
|
||||
// 2018-01-25: Inputs: Honoring the io.WantSetMousePos by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavMoveMouse is set).
|
||||
// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
|
||||
// 2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
|
||||
// 2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
|
||||
// 2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.

|

|
||||
// Implemented features:
|
||||
// [X] Platform: Clipboard support.
|
||||
// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen/Pen (Windows only).
|
||||
// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy GLFW_KEY_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
|
||||
// [X] Platform: Gamepad support. Enable with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
|
||||
// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange' (note: the resizing cursors requires GLFW 3.4+).
|

|
||||
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.

// dear imgui: Platform Backend for GLUT/FreeGLUT
|

// This needs to be used along with a Renderer (e.g. OpenGL2)
|

|

// !!! GLUT/FreeGLUT IS OBSOLETE PREHISTORIC SOFTWARE. Using GLUT is not recommended unless you really miss the 90's. !!!
|

// !!! If someone or something is teaching you GLUT today, you are being abused. Please show some resistance. !!!
|
||||
// !!! Nowadays, prefer using GLFW or SDL instead!
|
||||
|
||||
// Implemented features:
|
||||
// [X] Platform: Partial keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy GLUT values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
|
||||
// Issues:
|
||||
// [ ] Platform: GLUT is unable to distinguish e.g. Backspace from CTRL+H or TAB from CTRL+I
|
||||
// [ ] Platform: Missing horizontal mouse wheel support.
|
||||
// [ ] Platform: Missing mouse cursor shape/visibility support.
|

// CHANGELOG
|

// (minor and older changes stripped away, please see git history for details)
|
||||
// 2023-04-17: BREAKING: Removed call to ImGui::NewFrame() from ImGui_ImplGLUT_NewFrame(). Needs to be called from the main application loop, like with every other backends.
|
||||
// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
|
||||
// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
|
||||
// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
|
||||
// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
|
||||
// 2019-04-03: Misc: Renamed imgui_impl_freeglut.cpp/.h to imgui_impl_glut.cpp/.h.
|
||||
// 2019-03-25: Misc: Made io.DeltaTime always above zero.
|
||||
// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
|
||||
// 2018-03-22: Added GLUT Platform binding.

// dear imgui: Renderer Backend for Metal
|
||||
// This needs to be used along with a Platform Backend (e.g. OSX)
|
||||
|
||||
// Implemented features:
|
||||
// [X] Renderer: User texture binding. Use 'MTLTexture' as ImTextureID. Read the FAQ about ImTextureID!
|
||||
// [X] Renderer: Large meshes support (64k+ vertices) with 16-bit indices.
|
||||
|
||||
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
||||
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
|
||||
// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
|
||||
// Read online: https://github.com/ocornut/imgui/tree/master/docs
|
||||
|
||||
// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2022-08-23: Metal: Update deprecated property 'sampleCount'->'rasterSampleCount'.
|
||||
// 2022-07-05: Metal: Add dispatch synchronization.
|
||||
// 2022-06-30: Metal: Use __bridge for ARC based systems.
|
||||
// 2022-06-01: Metal: Fixed null dereference on exit inside command buffer completion handler.
|
||||
// 2022-04-27: Misc: Store backend data in a per-context struct, allowing to use this backend with multiple contexts.
|
||||
// 2022-01-03: Metal: Ignore ImDrawCmd where ElemCount == 0 (very rare but can technically be manufactured by user code).
|
||||
// 2021-12-30: Metal: Added Metal C++ support. Enable with '#define IMGUI_IMPL_METAL_CPP' in your imconfig.h file.
|
||||
// 2021-08-24: Metal: Fixed a crash when clipping rect larger than framebuffer is submitted. (#4464)
|
||||
// 2021-05-19: Metal: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
||||
// 2021-02-18: Metal: Change blending equation to preserve alpha in output buffer.
|
||||
// 2021-01-25: Metal: Fixed texture storage mode when building on Mac Catalyst.
|
||||
// 2019-05-29: Metal: Added support for large mesh (64K+ vertices), enable ImGuiBackendFlags_RendererHasVtxOffset flag.
|
||||
// 2019-04-30: Metal: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
||||
// 2019-02-11: Metal: Projecting clipping rectangles correctly using draw_data->FramebufferScale to allow multi-viewports for retina display.
|
||||
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
|
||||
// 2018-07-05: Metal: Added new Metal backend implementation.

|

|

// Implemented features:
|

// [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!
|
||||
|
||||
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.

// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
|
||||
// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.

// Read online: https://github.com/ocornut/imgui/tree/master/docs
|

|
||||
// **DO NOT USE THIS CODE IF YOUR CODE/ENGINE IS USING MODERN OPENGL (SHADERS, VBO, VAO, etc.)**
|

// **Prefer using the code in imgui_impl_opengl3.cpp**
|
||||
// This code is mostly provided as a reference to learn how ImGui integration works, because it is shorter to read.
|
||||
// If your code is using GL3+ context or any semi modern OpenGL calls, using this is likely to make everything more
|
||||
// complicated, will require your code to reset every single OpenGL attributes to their initial state, and might
|
||||
// confuse your GPU driver.
|
||||
// The GL2 code is unable to reset attributes or even call e.g. "glUseProgram(0)" because they don't exist in that API.
|
||||
|
||||
// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
||||
// 2021-12-08: OpenGL: Fixed mishandling of the the ImDrawCmd::IdxOffset field! This is an old bug but it never had an effect until some internal rendering changes in 1.86.
|
||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2021-05-19: OpenGL: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
||||
// 2021-01-03: OpenGL: Backup, setup and restore GL_SHADE_MODEL state, disable GL_STENCIL_TEST and disable GL_NORMAL_ARRAY client state to increase compatibility with legacy OpenGL applications.
|
||||
// 2020-01-23: OpenGL: Backup, setup and restore GL_TEXTURE_ENV to increase compatibility with legacy OpenGL applications.
|
||||
// 2019-04-30: OpenGL: Added support for special ImDrawCallback_ResetRenderState callback to reset render state.
|
||||
// 2019-02-11: OpenGL: Projecting clipping rectangles correctly using draw_data->FramebufferScale to allow multi-viewports for retina display.
|
||||
// 2018-11-30: Misc: Setting up io.BackendRendererName so it can be displayed in the About Window.
|
||||
// 2018-08-03: OpenGL: Disabling/restoring GL_LIGHTING and GL_COLOR_MATERIAL to increase compatibility with legacy OpenGL applications.
|
||||
// 2018-06-08: Misc: Extracted imgui_impl_opengl2.cpp/.h away from the old combined GLFW/SDL+OpenGL2 examples.
|
||||
// 2018-06-08: OpenGL: Use draw_data->DisplayPos and draw_data->DisplaySize to setup projection matrix and clipping rectangle.
|
||||
// 2018-02-16: Misc: Obsoleted the io.RenderDrawListsFn callback and exposed ImGui_ImplOpenGL2_RenderDrawData() in the .h file so you can call it yourself.
|
||||
// 2017-09-01: OpenGL: Save and restore current polygon mode.
|
||||
// 2016-09-10: OpenGL: Uploading font texture as RGBA32 to increase compatibility with users shaders (not ideal).
|
||||
// 2016-09-05: OpenGL: Fixed save and restore of current scissor rectangle.

// dear imgui: Renderer Backend for modern OpenGL with shaders / programmatic pipeline
|
||||
// - Desktop GL: 2.x 3.x 4.x
|
||||
// - Embedded GL: ES 2.0 (WebGL 1.0), ES 3.0 (WebGL 2.0)
|
||||
// This needs to be used along with a Platform Backend (e.g. GLFW, SDL, Win32, custom..)
|
||||
|
||||
// Implemented features:
|
||||
// [X] Renderer: User texture binding. Use 'GLuint' OpenGL texture identifier as void*/ImTextureID. Read the FAQ about ImTextureID!
|
||||
// [x] Renderer: Large meshes support (64k+ vertices) with 16-bit indices (Desktop OpenGL only).
|
||||
|
||||
// About WebGL/ES:
|
||||
// - You need to '#define IMGUI_IMPL_OPENGL_ES2' or '#define IMGUI_IMPL_OPENGL_ES3' to use WebGL or OpenGL ES.
|
||||
// - This is done automatically on iOS, Android and Emscripten targets.
|
||||
// - For other targets, the define needs to be visible from the imgui_impl_opengl3.cpp compilation unit. If unsure, define globally or in imconfig.h.
|
||||
|
||||
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
||||
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
|
||||
// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.

|

// About GLSL version:
|
||||
// The 'glsl_version' initialization parameter should be nullptr (default) or a "#version XXX" string.
|
||||
// On computer platform the GLSL version default to "#version 130". On OpenGL ES 3 platform it defaults to "#version 300 es"

//

// We embed our own OpenGL loader to not require user to provide their own or to have to use ours,

// enums/functions that we use in our imgui_impl_opengl3.cpp source file in order to be small.
|

//
|

// YOU SHOULD NOT NEED TO INCLUDE/USE THIS DIRECTLY. THIS IS USED BY imgui_impl_opengl3.cpp ONLY.

// THE REST OF YOUR APP SHOULD USE A DIFFERENT GL LOADER: ANY GL LOADER OF YOUR CHOICE.
|
||||
//
|
||||
// IF YOU GET BUILD ERRORS IN THIS FILE (commonly macro redefinitions or function redefinitions):
|

// IT LIKELY MEANS THAT YOU ARE BUILDING 'imgui_impl_opengl3.cpp' OR INCUDING 'imgui_impl_opengl3_loader.h'

// IN THE SAME COMPILATION UNIT AS ONE OF YOUR FILE WHICH IS USING A THIRD-PARTY OPENGL LOADER.

// (e.g. COULD HAPPEN IF YOU ARE DOING A UNITY/JUMBO BUILD, OR INCLUDING .CPP FILES FROM OTHERS)

// YOU SHOULD NOT BUILD BOTH IN THE SAME COMPILATION UNIT.

// BUT IF YOU REALLY WANT TO, you can '#define IMGUI_IMPL_OPENGL_LOADER_CUSTOM' and imgui_impl_opengl3.cpp

||||
// 2022-04-27: Misc: Store backend data in a per-context struct, allowing to use this backend with multiple contexts.
|
||||
// 2022-03-22: Inputs: Monitor NSKeyUp events to catch missing keyUp for key when user press Cmd + key

|
||||
// 2021-01-20: Inputs: calling new io.AddKeyAnalogEvent() for gamepad support, instead of writing directly to io.NavInputs[].
|
||||
// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
|

/**

KeyEventResponder implements the NSTextInputClient protocol as is required by the macOS text input manager.
|
||||
|
||||
The macOS text input manager is invoked by calling the interpretKeyEvents method from the keyDown method.
|
||||
Keyboard events are then evaluated by the macOS input manager and valid text input is passed back via the
|
||||
insertText:replacementRange method.

// dear imgui: Platform Backend for SDL2
|

// This needs to be used along with a Renderer (e.g. DirectX11, OpenGL3, Vulkan..)
|
||||
// (Info: SDL2 is a cross-platform general purpose library for handling windows, inputs, graphics context creation, etc.)
|
||||
// (Prefer SDL 2.0.5+ for full feature support.)
|
||||
|
||||
// Implemented features:
|
||||
// [X] Platform: Clipboard support.
|
||||
// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen.
|
||||
// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy SDL_SCANCODE_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
|
||||
// [X] Platform: Gamepad support. Enabled with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
|
||||
// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
|
||||
// [X] Platform: Basic IME support. App needs to call 'SDL_SetHint(SDL_HINT_IME_SHOW_UI, "1");' before SDL_CreateWindow()!.
|
||||
|
||||
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
||||
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
|
||||
// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.

|

// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2023-04-06: Inputs: Avoid calling SDL_StartTextInput()/SDL_StopTextInput() as they don't only pertain to IME. It's unclear exactly what their relation is to IME. (#6306)
|
||||
// 2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen. (#2702)
|
||||
// 2023-02-23: Accept SDL_GetPerformanceCounter() not returning a monotonically increasing value. (#6189, #6114, #3644)
|
||||
// 2023-02-07: Implement IME handler (io.SetPlatformImeDataFn will call SDL_SetTextInputRect()/SDL_StartTextInput()).
|
||||
// 2023-02-07: *BREAKING CHANGE* Renamed this backend file from imgui_impl_sdl.cpp/.h to imgui_impl_sdl2.cpp/.h in prevision for the future release of SDL3.
|
||||
// 2023-02-02: Avoid calling SDL_SetCursor() when cursor has not changed, as the function is surprisingly costly on Mac with latest SDL (may be fixed in next SDL version).
|
||||
// 2023-02-02: Added support for SDL 2.0.18+ preciseX/preciseY mouse wheel data for smooth scrolling + Scaling X value on Emscripten (bug?). (#4019, #6096)
|
||||
// 2023-02-02: Removed SDL_MOUSEWHEEL value clamping, as values seem correct in latest Emscripten. (#4019)
|
||||
// 2023-02-01: Flipping SDL_MOUSEWHEEL 'wheel.x' value to match other backends and offer consistent horizontal scrolling direction. (#4019, #6096, #1463)
|
||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
||||
// 2022-09-26: Inputs: Disable SDL 2.0.22 new "auto capture" (SDL_HINT_MOUSE_AUTO_CAPTURE) which prevents drag and drop across windows for multi-viewport support + don't capture when drag and dropping. (#5710)
|
||||
// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
|
||||
// 2022-03-22: Inputs: Fix mouse position issues when dragging outside of boundaries. SDL_CaptureMouse() erroneously still gives out LEAVE events when hovering OS decorations.
|
||||
// 2022-03-22: Inputs: Added support for extra mouse buttons (SDL_BUTTON_X1/SDL_BUTTON_X2).
|
||||
// 2022-02-04: Added SDL_Renderer* parameter to ImGui_ImplSDL2_InitForSDLRenderer(), so we can use SDL_GetRendererOutputSize() instead of SDL_GL_GetDrawableSize() when bound to a SDL_Renderer.
|
||||
// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
|
||||
// 2021-01-20: Inputs: calling new io.AddKeyAnalogEvent() for gamepad support, instead of writing directly to io.NavInputs[].
|
||||
// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
|
||||
// 2022-01-17: Inputs: always update key mods next and before key event (not in NewFrame) to fix input queue with very low framerates.
|
||||
// 2022-01-12: Update mouse inputs using SDL_MOUSEMOTION/SDL_WINDOWEVENT_LEAVE + fallback to provide it when focused but not hovered/captured. More standard and will allow us to pass it to future input queue API.
|
||||
// 2022-01-12: Maintain our own copy of MouseButtonsDown mask instead of using ImGui::IsAnyMouseDown() which will be obsoleted.
|
||||
// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
|
||||
// 2021-08-17: Calling io.AddFocusEvent() on SDL_WINDOWEVENT_FOCUS_GAINED/SDL_WINDOWEVENT_FOCUS_LOST.
|
||||
// 2021-07-29: Inputs: MousePos is correctly reported when the host platform window is hovered but not focused (using SDL_GetMouseFocus() + SDL_HINT_MOUSE_FOCUS_CLICKTHROUGH, requires SDL 2.0.5+)
|
||||
// 2021-06-29: *BREAKING CHANGE* Removed 'SDL_Window* window' parameter to ImGui_ImplSDL2_NewFrame() which was unnecessary.
|
||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2021-03-22: Rework global mouse pos availability check listing supported platforms explicitly, effectively fixing mouse access on Raspberry Pi. (#2837, #3950)
|
||||
// 2020-05-25: Misc: Report a zero display-size when window is minimized, to be consistent with other backends.
|
||||
// 2020-02-20: Inputs: Fixed mapping for ImGuiKey_KeyPadEnter (using SDL_SCANCODE_KP_ENTER instead of SDL_SCANCODE_RETURN2).
|
||||
// 2019-12-17: Inputs: On Wayland, use SDL_GetMouseState (because there is no global mouse state).
|
||||
// 2019-12-05: Inputs: Added support for ImGuiMouseCursor_NotAllowed mouse cursor.
|
||||
// 2019-07-21: Inputs: Added mapping for ImGuiKey_KeyPadEnter.
|
||||
// 2019-04-23: Inputs: Added support for SDL_GameController (if ImGuiConfigFlags_NavEnableGamepad is set by user application).
|
||||
// 2019-03-12: Misc: Preserve DisplayFramebufferScale when main window is minimized.
|
||||
// 2018-12-21: Inputs: Workaround for Android/iOS which don't seem to handle focus related calls.
|
||||
// 2018-11-30: Misc: Setting up io.BackendPlatformName so it can be displayed in the About Window.
|
||||
// 2018-11-14: Changed the signature of ImGui_ImplSDL2_ProcessEvent() to take a 'const SDL_Event*'.
|
||||
// 2018-08-01: Inputs: Workaround for Emscripten which doesn't seem to handle focus related calls.
|
||||
// 2018-06-29: Inputs: Added support for the ImGuiMouseCursor_Hand cursor.
|
||||
// 2018-06-08: Misc: Extracted imgui_impl_sdl.cpp/.h away from the old combined SDL2+OpenGL/Vulkan examples.
|
||||
// 2018-06-08: Misc: ImGui_ImplSDL2_InitForOpenGL() now takes a SDL_GLContext parameter.
|
||||
// 2018-05-09: Misc: Fixed clipboard paste memory leak (we didn't call SDL_FreeMemory on the data returned by SDL_GetClipboardText).
|
||||
// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors flag + honor ImGuiConfigFlags_NoMouseCursorChange flag.
|
||||
// 2018-02-16: Inputs: Added support for mouse cursors, honoring ImGui::GetMouseCursor() value.
|
||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
|
||||
// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
|
||||
// 2018-02-05: Misc: Using SDL_GetPerformanceCounter() instead of SDL_GetTicks() to be able to handle very high framerate (1000+ FPS).
|
||||
// 2018-02-05: Inputs: Keyboard mapping is using scancodes everywhere instead of a confusing mixture of keycodes and scancodes.
|
||||
// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
|
||||
// 2018-01-19: Inputs: When available (SDL 2.0.4+) using SDL_CaptureMouse() to retrieve coordinates outside of client area when dragging. Otherwise (SDL 2.0.3 and before) testing for SDL_WINDOW_INPUT_FOCUS instead of SDL_WINDOW_MOUSE_FOCUS.
|
||||
// 2018-01-18: Inputs: Added mapping for ImGuiKey_Insert.
|
||||
// 2017-08-25: Inputs: MousePos set to -FLT_MAX,-FLT_MAX when mouse is unavailable/missing (instead of -1,-1).
|
||||
// 2016-10-15: Misc: Added a void* user_data parameter to Clipboard function handlers.

// dear imgui: Platform Backend for SDL3 (*EXPERIMENTAL*)

// This needs to be used along with a Renderer (e.g. DirectX11, OpenGL3, Vulkan..)
|
||||
// (Info: SDL3 is a cross-platform general purpose library for handling windows, inputs, graphics context creation, etc.)
|
||||
// (IMPORTANT: SDL 3.0.0 is NOT YET RELEASED. IT IS POSSIBLE THAT ITS SPECS/API WILL CHANGE BEFORE RELEASE)
|
||||
|
||||
// Implemented features:
|
||||
// [X] Platform: Clipboard support.
|
||||
// [X] Platform: Mouse support. Can discriminate Mouse/TouchScreen.
|
||||
// [X] Platform: Keyboard support. Since 1.87 we are using the io.AddKeyEvent() function. Pass ImGuiKey values to all key functions e.g. ImGui::IsKeyPressed(ImGuiKey_Space). [Legacy SDL_SCANCODE_* values will also be supported unless IMGUI_DISABLE_OBSOLETE_KEYIO is set]
|
||||
// [X] Platform: Gamepad support. Enabled with 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad'.
|
||||
// [X] Platform: Mouse cursor shape and visibility. Disable with 'io.ConfigFlags |= ImGuiConfigFlags_NoMouseCursorChange'.
|
||||
// Missing features:
|
||||
// [x] Platform: Basic IME support. Position somehow broken in SDL3 + app needs to call 'SDL_SetHint(SDL_HINT_IME_SHOW_UI, "1");' before SDL_CreateWindow()!.

// dear imgui: Renderer for WebGPU
|
||||
// This needs to be used along with a Platform Binding (e.g. GLFW)
|
||||
// (Please note that WebGPU is currently experimental, will not run on non-beta browsers, and may break.)
|
||||
|
||||
// Implemented features:
|
||||
// [X] Renderer: User texture binding. Use 'WGPUTextureView' as ImTextureID. Read the FAQ about ImTextureID!
|
||||
// [X] Renderer: Large meshes support (64k+ vertices) with 16-bit indices.
|
||||
|
||||
// You can use unmodified imgui_impl_* files in your project. See examples/ folder for examples of using this.
|
||||
// Prefer including the entire imgui/ repository into your project (either as a copy or as a submodule), and only build the backends you need.
|
||||
// If you are new to Dear ImGui, read documentation from the docs/ folder + read the top of imgui.cpp.
|

// Read online: https://github.com/ocornut/imgui/tree/master/docs
|
||||
|
||||
// CHANGELOG
|
||||
// (minor and older changes stripped away, please see git history for details)
|
||||
// 2023-04-11: Align buffer sizes. Use WGSL shaders instead of precompiled SPIR-V.
|
||||
// 2023-04-11: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2023-01-25: Revert automatic pipeline layout generation (see https://github.com/gpuweb/gpuweb/issues/2470)
|
||||
// 2022-11-24: Fixed validation error with default depth buffer settings.
|
||||
// 2022-11-10: Fixed rendering when a depth buffer is enabled. Added 'WGPUTextureFormat depth_format' parameter to ImGui_ImplWGPU_Init().
|
||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
||||
// 2021-11-29: Passing explicit buffer sizes to wgpuRenderPassEncoderSetVertexBuffer()/wgpuRenderPassEncoderSetIndexBuffer().
|
||||
// 2021-08-24: Fixed for latest specs.
|
||||
// 2021-05-24: Add support for draw_data->FramebufferScale.
|
||||
// 2021-05-19: Replaced direct access to ImDrawCmd::TextureId with a call to ImDrawCmd::GetTexID(). (will become a requirement)
|
||||
// 2021-05-16: Update to latest WebGPU specs (compatible with Emscripten 2.0.20 and Chrome Canary 92).
|
||||
// 2021-02-18: Change blending equation to preserve alpha in output buffer.
|

// 2023-04-19: Added ImGui_ImplWin32_InitForOpenGL() to facilitate combining raw Win32/Winapi with OpenGL. (#3218)
|
||||
// 2023-04-04: Inputs: Added support for io.AddMouseSourceEvent() to discriminate ImGuiMouseSource_Mouse/ImGuiMouseSource_TouchScreen/ImGuiMouseSource_Pen. (#2702)
|
||||
// 2023-02-15: Inputs: Use WM_NCMOUSEMOVE / WM_NCMOUSELEAVE to track mouse position over non-client area (e.g. OS decorations) when app is not focused. (#6045, #6162)
|
||||
// 2023-02-02: Inputs: Flipping WM_MOUSEHWHEEL (horizontal mouse-wheel) value to match other backends and offer consistent horizontal scrolling direction. (#4019, #6096, #1463)
|
||||
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
|
||||
// 2022-09-28: Inputs: Convert WM_CHAR values with MultiByteToWideChar() when window class was registered as MBCS (not Unicode).
|
||||
// 2022-09-26: Inputs: Renamed ImGuiKey_ModXXX introduced in 1.87 to ImGuiMod_XXX (old names still supported).
|
||||
// 2022-01-26: Inputs: replaced short-lived io.AddKeyModsEvent() (added two weeks ago) with io.AddKeyEvent() using ImGuiKey_ModXXX flags. Sorry for the confusion.
|
||||
// 2021-01-20: Inputs: calling new io.AddKeyAnalogEvent() for gamepad support, instead of writing directly to io.NavInputs[].
|
||||
// 2022-01-17: Inputs: calling new io.AddMousePosEvent(), io.AddMouseButtonEvent(), io.AddMouseWheelEvent() API (1.87+).
|
||||
// 2022-01-17: Inputs: always update key mods next and before a key event (not in NewFrame) to fix input queue with very low framerates.
|
||||
// 2022-01-12: Inputs: Update mouse inputs using WM_MOUSEMOVE/WM_MOUSELEAVE + fallback to provide it when focused but not hovered/captured. More standard and will allow us to pass it to future input queue API.
|
||||
// 2022-01-12: Inputs: Maintain our own copy of MouseButtonsDown mask instead of using ImGui::IsAnyMouseDown() which will be obsoleted.
|
||||
// 2022-01-10: Inputs: calling new io.AddKeyEvent(), io.AddKeyModsEvent() + io.SetKeyEventNativeData() API (1.87+). Support for full ImGuiKey range.
|
||||
// 2021-12-16: Inputs: Fill VK_LCONTROL/VK_RCONTROL/VK_LSHIFT/VK_RSHIFT/VK_LMENU/VK_RMENU for completeness.
|
||||
// 2021-08-17: Calling io.AddFocusEvent() on WM_SETFOCUS/WM_KILLFOCUS messages.
|
||||
// 2021-08-02: Inputs: Fixed keyboard modifiers being reported when host window doesn't have focus.
|
||||
// 2021-07-29: Inputs: MousePos is correctly reported when the host platform window is hovered but not focused (using TrackMouseEvent() to receive WM_MOUSELEAVE events).
|
||||
// 2021-06-29: Reorganized backend to pull data from a single structure to facilitate usage with multiple-contexts (all g_XXXX access changed to bd->XXXX).
|
||||
// 2021-06-08: Fixed ImGui_ImplWin32_EnableDpiAwareness() and ImGui_ImplWin32_GetDpiScaleForMonitor() to handle Windows 8.1/10 features without a manifest (per-monitor DPI, and properly calls SetProcessDpiAwareness() on 8.1).
|
||||
// 2021-03-23: Inputs: Clearing keyboard down array when losing focus (WM_KILLFOCUS).
|
||||
// 2021-02-18: Added ImGui_ImplWin32_EnableAlphaCompositing(). Non Visual Studio users will need to link with dwmapi.lib (MinGW/gcc: use -ldwmapi).
|
||||
// 2021-02-17: Fixed ImGui_ImplWin32_EnableDpiAwareness() attempting to get SetProcessDpiAwareness from shcore.dll on Windows 8 whereas it is only supported on Windows 8.1.
|
||||
// 2021-01-25: Inputs: Dynamically loading XInput DLL.
|
||||
// 2020-12-04: Misc: Fixed setting of io.DisplaySize to invalid/uninitialized data when after hwnd has been closed.
|
||||
// 2020-03-03: Inputs: Calling AddInputCharacterUTF16() to support surrogate pairs leading to codepoint >= 0x10000 (for more complete CJK inputs)

|
||||
// 2020-01-14: Inputs: Added support for #define IMGUI_IMPL_WIN32_DISABLE_GAMEPAD/IMGUI_IMPL_WIN32_DISABLE_LINKING_XINPUT.
|
||||
// 2019-12-05: Inputs: Added support for ImGuiMouseCursor_NotAllowed mouse cursor.
|
||||
// 2019-05-11: Inputs: Don't filter value from WM_CHAR before calling AddInputCharacter().
|
||||
// 2019-01-17: Misc: Using GetForegroundWindow()+IsChild() instead of GetActiveWindow() to be compatible with windows created in a different thread or parent.
|
||||
// 2019-01-17: Inputs: Added support for mouse buttons 4 and 5 via WM_XBUTTON* messages.
|
||||
// 2019-01-15: Inputs: Added support for XInput gamepads (if ImGuiConfigFlags_NavEnableGamepad is set by user application).

||||
// 2018-06-08: Misc: Extracted imgui_impl_win32.cpp/.h away from the old combined DX9/DX10/DX11/DX12 examples.
|
||||
// 2018-03-20: Misc: Setup io.BackendFlags ImGuiBackendFlags_HasMouseCursors and ImGuiBackendFlags_HasSetMousePos flags + honor ImGuiConfigFlags_NoMouseCursorChange flag.
|
||||
// 2018-02-20: Inputs: Added support for mouse cursors (ImGui::GetMouseCursor() value and WM_SETCURSOR message handling).
|
||||
// 2018-02-06: Inputs: Added mapping for ImGuiKey_Space.
|
||||
// 2018-02-06: Inputs: Honoring the io.WantSetMousePos by repositioning the mouse (when using navigation and ImGuiConfigFlags_NavMoveMouse is set).
|
||||
// 2018-02-06: Misc: Removed call to ImGui::Shutdown() which is not available from 1.60 WIP, user needs to call CreateContext/DestroyContext themselves.
|
||||
// 2018-01-20: Inputs: Added Horizontal Mouse Wheel support.
|
||||
// 2018-01-08: Inputs: Added mapping for ImGuiKey_Insert.

## Dear ImGui: Backends
|
||||
|
||||
**The backends/ folder contains backends for popular platforms/graphics API, which you can use in
|
||||
your application or engine to easily integrate Dear ImGui.** Each backend is typically self-contained in a pair of files: imgui_impl_XXXX.cpp + imgui_impl_XXXX.h.
|
||||
|
||||
- The 'Platform' backends are in charge of: mouse/keyboard/gamepad inputs, cursor shape, timing, and windowing.<BR>
|
||||
e.g. Windows ([imgui_impl_win32.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_win32.cpp)), GLFW ([imgui_impl_glfw.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_glfw.cpp)), SDL2 ([imgui_impl_sdl2.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_sdl2.cpp)), etc.
|
||||
|
||||
- The 'Renderer' backends are in charge of: creating atlas texture, and rendering imgui draw data.<BR>
|
||||
e.g. DirectX11 ([imgui_impl_dx11.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_dx11.cpp)), OpenGL/WebGL ([imgui_impl_opengl3.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_opengl3.cpp)), Vulkan ([imgui_impl_vulkan.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_vulkan.cpp)), etc.
|
||||
|
||||
- For some high-level frameworks, a single backend usually handles both 'Platform' and 'Renderer' parts.<BR>
|
||||
e.g. Allegro 5 ([imgui_impl_allegro5.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_allegro5.cpp)). If you end up creating a custom backend for your engine, you may want to do the same.
|
||||
|
||||
An application usually combines one Platform backend + one Renderer backend + main Dear ImGui sources.
|
||||
For example, the [example_win32_directx11](https://github.com/ocornut/imgui/tree/master/examples/example_win32_directx11) application combines imgui_impl_win32.cpp + imgui_impl_dx11.cpp. There are 20+ examples in the [examples/](https://github.com/ocornut/imgui/blob/master/examples/) folder. See [EXAMPLES.MD](https://github.com/ocornut/imgui/blob/master/docs/EXAMPLES.md) for details.
|
||||
|
||||
**Once Dear ImGui is setup and running, run and refer to `ImGui::ShowDemoWindow()` in imgui_demo.cpp for usage of the end-user API.**
|
||||
|
||||
|
||||
### What are backends?
|
||||
|
||||
Dear ImGui is highly portable and only requires a few things to run and render, typically:
|
||||
|
||||
- Required: providing mouse/keyboard inputs (fed into the `ImGuiIO` structure).
|
||||
- Required: uploading the font atlas texture into graphics memory.
|
||||
- Required: rendering indexed textured triangles with a clipping rectangle.
|
||||
|
||||
Extra features are opt-in, our backends try to support as many as possible:
|
||||
|
||||
- Optional: custom texture binding support.
|
||||
- Optional: clipboard support.
|
||||
- Optional: gamepad support.
|
||||
- Optional: mouse cursor shape support.
|
||||
- Optional: IME support.
|
||||
- Optional: multi-viewports support.
|
||||
etc.
|
||||
|
||||
This is essentially what each backend is doing + obligatory portability cruft. Using default backends ensure you can get all those features including the ones that would be harder to implement on your side (e.g. multi-viewports support).
|
||||
|
||||
It is important to understand the difference between the core Dear ImGui library (files in the root folder)
|
||||
and the backends which we are describing here (backends/ folder).
|
||||
|
||||
- Some issues may only be backend or platform specific.
|
||||
- You should be able to write backends for pretty much any platform and any 3D graphics API.
|
||||
e.g. you can get creative and use software rendering or render remotely on a different machine.
|
||||
|
||||
|
||||
### Integrating a backend

|
||||
|
||||
### Backends for third-party frameworks, graphics API or other languages
|
||||
|
||||
See https://github.com/ocornut/imgui/wiki/Bindings for the full list (e.g. Adventure Game Studio, Cinder, Cocos2d-x, Game Maker Studio2, Godot, LÖVE+LUA, Magnum, Monogame, Ogre, openFrameworks, OpenSceneGraph, SFML, Sokol, Unity, Unreal Engine and many others).
|
||||
|
||||
### Recommended Backends
|
||||
|
||||
If you are not sure which backend to use, the recommended platform/frameworks for portable applications:
|
||||
|
||||
|Library |Website |Backend |Note |
|
||||
|--------|--------|--------|-----|
|
||||
| GLFW | https://github.com/glfw/glfw | imgui_impl_glfw.cpp | |
|
||||
| SDL2 | https://www.libsdl.org | imgui_impl_sdl2.cpp | |
|
||||
| Sokol | https://github.com/floooh/sokol | [util/sokol_imgui.h](https://github.com/floooh/sokol/blob/master/util/sokol_imgui.h) | Lower-level than GLFW/SDL |
|
||||
|
||||
|
||||
### Using a custom engine?
|
||||
|
||||
You will likely be tempted to start by rewrite your own backend using your own custom/high-level facilities...<BR>
|
||||
Think twice!
|
||||
|
||||
If you are new to Dear ImGui, first try using the existing backends as-is.
|
||||
You will save lots of time integrating the library.
|
||||
You can LATER decide to rewrite yourself a custom backend if you really need to.
|
||||
In most situations, custom backends have fewer features and more bugs than the standard backends we provide.
|
||||
If you want portability, you can use multiple backends and choose between them either at compile time
|
||||
or at runtime.
|
||||
|
||||
**Example A**: your engine is built over Windows + DirectX11 but you have your own high-level rendering
|
||||
system layered over DirectX11.<BR>
|
||||
Suggestion: try using imgui_impl_win32.cpp + imgui_impl_dx11.cpp first.
|
||||
Once it works, if you really need it, you can replace the imgui_impl_dx11.cpp code with a
|
||||
custom renderer using your own rendering functions, and keep using the standard Win32 code etc.
|
||||
|
||||
**Example B**: your engine runs on Windows, Mac, Linux and uses DirectX11, Metal, and Vulkan respectively.<BR>
|
||||
Suggestion: use multiple generic backends!
|
||||
Once it works, if you really need it, you can replace parts of backends with your own abstractions.
|
||||
|
||||
**Example C**: your engine runs on platforms we can't provide public backends for (e.g. PS4/PS5, Switch),
|
||||
and you have high-level systems everywhere.<BR>
|
||||
Suggestion: try using a non-portable backend first (e.g. win32 + underlying graphics API) to get
|
||||
your desktop builds working first. This will get you running faster and get your acquainted with
|
||||
how Dear ImGui works and is setup. You can then rewrite a custom backend using your own engine API...
|
||||
|
||||
Generally:
|
||||
It is unlikely you will add value to your project by creating your own backend.
|
||||
|
||||
Also:
|
||||
The [multi-viewports feature](https://github.com/ocornut/imgui/issues/1542) of the 'docking' branch allows
|
||||
Dear ImGui windows to be seamlessly detached from the main application window. This is achieved using an
|
||||
extra layer to the Platform and Renderer backends, which allows Dear ImGui to communicate platform-specific
|
||||
requests such as: "create an additional OS window", "create a render context", "get the OS position of this
|
||||
window" etc. See 'ImGuiPlatformIO' for details.
|
||||
Supporting the multi-viewports feature correctly using 100% of your own abstractions is more difficult
|
||||
than supporting single-viewport.
|
||||
If you decide to use unmodified imgui_impl_XXXX.cpp files, you can automatically benefit from
|
||||
improvements and fixes related to viewports and platform windows without extra work on your side.

## Getting Started & General Advice
|
||||
|
||||
- Article: [How To Ask Good Questions](https://bit.ly/3nwRnx1).
|
||||
- Please browse the [Wiki](https://github.com/ocornut/imgui/wiki) to find code snippets, links and other resources (e.g. [Getting Started](https://github.com/ocornut/imgui/wiki/Getting-Started), [Useful extensions](https://github.com/ocornut/imgui/wiki/Useful-Extensions)).
|
||||
- Please read [docs/FAQ.md](https://github.com/ocornut/imgui/blob/master/docs/FAQ.md).
|
||||
- Please read [docs/FONTS.md](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md) if your question relates to fonts or text.
|
||||
- Please read one of the [examples/](https://github.com/ocornut/imgui/tree/master/examples) application if your question relates to setting up Dear ImGui.
|
||||
- Please run `ImGui::ShowDemoWindow()` to explore the demo and its sources.
|
||||
- Please use the search function of your IDE to search in for comments related to your situation.
|
||||
- Please use the search function of GitHub to look for similar issues. You may [browse issues by Labels](https://github.com/ocornut/imgui/labels).
|
||||
- Please use a web search engine to look for similar issues.
|
||||
- If you get a crash or assert, use a debugger to locate the line triggering it and read the comments around.
|
||||
- Please don't be a [Help Vampire](https://slash7.com/2006/12/22/vampires/).
|
||||
|
||||
## Issues vs Discussions
|
||||
|
||||
If you:
|
||||
- Cannot BUILD or LINK examples.
|
||||
- Cannot BUILD, or LINK, or RUN Dear ImGui in your application or custom engine.
|
||||
- Cannot LOAD a font.
|
||||
|
||||
Then please [use the Discussions forums](https://github.com/ocornut/imgui/discussions) instead of opening an issue.
|
||||
|
||||
If Dear ImGui is successfully showing in your app and you have used Dear ImGui before, you can open an issue. Any form of discussions is welcome as a new issue.
|
||||
|
||||
## How to open an issue
|
||||
|
||||
You may use the Issue Tracker to submit bug reports, feature requests or suggestions. You may ask for help or advice as well. But **PLEASE CAREFULLY READ THIS WALL OF TEXT. ISSUES IGNORING THOSE GUIDELINES MAY BE CLOSED. USERS IGNORING THOSE GUIDELINES MIGHT BE BLOCKED.**
|
||||
|
||||
Please do your best to clarify your request. The amount of incomplete or ambiguous requests due to people not following those guidelines is often overwhelming. Issues created without the requested information may be closed prematurely. Exceptionally entitled, impolite, or lazy requests may lead to bans.
|
||||
|
||||
**PLEASE UNDERSTAND THAT OPEN-SOURCE SOFTWARE LIVES OR DIES BY THE AMOUNT OF ENERGY MAINTAINERS CAN SPARE. WE HAVE LOTS OF STUFF TO DO. THIS IS AN ATTENTION ECONOMY AND MANY LAZY OR MINOR ISSUES ARE HOGGING OUR ATTENTION AND DRAINING ENERGY, TAKING US AWAY FROM MORE IMPORTANT WORK.**
|
||||
|
||||
Steps:
|
||||
|
||||
- Article: [How To Ask Good Questions](https://bit.ly/3nwRnx1).
|
||||
- **PLEASE DO FILL THE REQUESTED NEW ISSUE TEMPLATE.** Including Dear ImGui version number, branch name, platform/renderer back-ends (imgui_impl_XXX files), operating system.
|
||||
- **Try to be explicit with your GOALS, your EXPECTATIONS and what you have tried**. Be mindful of [The XY Problem](http://xyproblem.info/). What you have in mind or in your code is not obvious to other people. People frequently discuss problems and suggest incorrect solutions without first clarifying their goals. When requesting a new feature, please describe the usage context (how you intend to use it, why you need it, etc.). If you tried something and it failed, show us what you tried.
|
||||
- **Attach screenshots (or GIF/video) to clarify the context**. They often convey useful information that is omitted by the description. You can drag pictures/files in the message edit box. Avoid using 3rd party image hosting services, prefer the long-term longevity of GitHub attachments (you can drag pictures into your post). On Windows, you can use [ScreenToGif](https://www.screentogif.com/) to easily capture .gif files.
|
||||
- **If you are discussing an assert or a crash, please provide a debugger callstack**. Never state "it crashes" without additional information. If you don't know how to use a debugger and retrieve a callstack, learning about it will be useful.
|
||||
- **Please make sure that your project has asserts enabled.** Calls to IM_ASSERT() are scattered in the code to help catch common issues. When an assert is triggered read the comments around it. By default IM_ASSERT() calls the standard assert() function. To verify that your asserts are enabled, add the line `IM_ASSERT(false);` in your main() function. Your application should display an error message and abort. If your application doesn't report an error, your asserts are disabled.
|
||||
- **Please provide a Minimal, Complete, and Verifiable Example ([MCVE](https://stackoverflow.com/help/mcve)) to demonstrate your problem**. An ideal submission includes a small piece of code that anyone can paste into one of the examples applications (examples/../main.cpp) or demo (imgui_demo.cpp) to understand and reproduce it. Narrowing your problem to its shortest and purest form is the easiest way to understand it. Please test your shortened code to ensure it exhibits the problem. **Often while creating the MCVE you will end up solving the problem!** Many questions that are missing a standalone verifiable example are missing the actual cause of their issue in the description, which ends up wasting everyone's time.
|
||||
- Please state if you have made substantial modifications to your copy of Dear ImGui or the back-end.
|
||||
- If you are not calling Dear ImGui directly from C++, please provide information about your Language and the wrapper/binding you are using.
|
||||
- Be mindful that messages are being sent to the mailbox of "Watching" users. Try to proofread your messages before sending them. Edits are not seen by those users unless they browse the site.
|
||||
|
||||
**Some unfortunate words of warning**
|
||||
- If you are involved in cheating schemes (e.g. DLL injection) for competitive online multiplayer games, please don't try posting here. We won't answer and you will be blocked. It doesn't matter if your question relates to said project. We've had too many of you and need to project our time and sanity.
|
||||
- Due to frequent abuse of this service from the aforementioned users, if your GitHub account is anonymous and was created five minutes ago please understand that your post will receive more scrutiny and incomplete questions will be harshly dismissed.
|
||||
|
||||
If you have been using Dear ImGui for a while or have been using C/C++ for several years or have demonstrated good behavior here, it is ok to not fulfill every item to the letter. Those are guidelines and experienced users or members of the community will know which information is useful in a given context.
|
||||
|
||||
## How to open a Pull Request
|
||||
|
||||
- **Please understand that by submitting a PR you are also submitting a request for the maintainer to review your code and then take over its maintenance.** PR should be crafted both in the interest of the end-users and also to ease the maintainer into understanding and accepting it.
|
||||
- Many PRs are useful to demonstrate a need and a possible solution but aren't adequate for merging (causing other issues, not seeing other aspects of the big picture, etc.). In doubt, don't hesitate to push a PR because that is always the first step toward finding the mergeable solution! Even if a PR stays unmerged for a long time, its presence can be useful for other users and helps toward finding a general solution.
|
||||
- **When adding a feature,** please describe the usage context (how you intend to use it, why you need it, etc.). Be mindful of [The XY Problem](http://xyproblem.info/).
|
||||
- **When fixing a warning or compilation problem,** please post the compiler log and specify the compiler version and platform you are using.
|
||||
- **Attach screenshots (or GIF/video) to clarify the context and demonstrate the feature at a glance.** You can drag pictures/files in the message edit box. Prefer the long-term longevity of GitHub attachments over 3rd party hosting (you can drag pictures into your post).
|
||||
- **Make sure your code follows the coding style already used in the codebase:** 4 spaces indentations (no tabs), `local_variable`, `FunctionName()`, `MemberName`, `// Text Comment`, `//CodeComment();`, C-style casts, etc.. We don't use modern C++ idioms and tend to use only a minimum of C++11 features. The applications under examples/ are generally less consistent because they sometimes try to mimic the coding style often adopted by a certain ecosystem (e.g. DirectX-related code tend to use the style of their sample).
|
||||
- **Make sure you create a branch dedicated to the pull request**. In Git, 1 PR is associated to 1 branch. If you keep pushing to the same branch after you submitted the PR, your new commits will appear in the PR (we can still cherry-pick individual commits).

## Dear ImGui: Examples
|
||||
|
||||
**The [examples/](https://github.com/ocornut/imgui/blob/master/examples) folder example applications (standalone, ready-to-build) for variety of
|
||||
platforms and graphics APIs.** They all use standard backends from the [backends/](https://github.com/ocornut/imgui/blob/master/backends) folder (see [BACKENDS.md](https://github.com/ocornut/imgui/blob/master/docs/BACKENDS.md)).
|
||||
|
||||
The purpose of Examples is to showcase integration with backends, let you try Dear ImGui, and guide you toward
|
||||
integrating Dear ImGui in your own application/game/engine.
|
||||
**Once Dear ImGui is setup and running, run and refer to `ImGui::ShowDemoWindow()` in imgui_demo.cpp for usage of the end-user API.**
|
||||
|
||||
You can find Windows binaries for some of those example applications at:
|
||||
http://www.dearimgui.com/binaries
|
||||
|
||||
|
||||
### Getting Started
|
||||
|
||||
Integration in a typical existing application, should take <20 lines when using standard backends.
|
||||
|
||||
```cpp
|
||||
At initialization:
|
||||
call ImGui::CreateContext()
|
||||
call ImGui_ImplXXXX_Init() for each backend.
|
||||
|
||||
At the beginning of your frame:
|
||||
call ImGui_ImplXXXX_NewFrame() for each backend.
|
||||
call ImGui::NewFrame()
|
||||
|
||||
At the end of your frame:
|
||||
call ImGui::Render()
|
||||
call ImGui_ImplXXXX_RenderDrawData() for your Renderer backend.
|
||||
|
||||
At shutdown:
|
||||
call ImGui_ImplXXXX_Shutdown() for each backend.
|
||||
call ImGui::DestroyContext()
|
||||
```
|
||||
|
||||
Example (using [backends/imgui_impl_win32.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_win32.cpp) + [backends/imgui_impl_dx11.cpp](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_dx11.cpp)):
|
||||
|
||||
```cpp
|
||||
// Create a Dear ImGui context, setup some options
|
||||
ImGui::CreateContext();
|
||||
ImGuiIO& io = ImGui::GetIO();
|
||||
io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard; // Enable some options
|
||||
|
||||
// Initialize Platform + Renderer backends (here: using imgui_impl_win32.cpp + imgui_impl_dx11.cpp)
|
||||
ImGui_ImplWin32_Init(my_hwnd);
|
||||
ImGui_ImplDX11_Init(my_d3d_device, my_d3d_device_context);
|
||||
|
||||
// Application main loop
|
||||
while (true)
|
||||
{
|
||||
// Beginning of frame: update Renderer + Platform backend, start Dear ImGui frame
|
||||
ImGui_ImplDX11_NewFrame();
|
||||
ImGui_ImplWin32_NewFrame();
|
||||
ImGui::NewFrame();
|
||||
|
||||
// Any application code here
|
||||
ImGui::Text("Hello, world!");
|
||||
|
||||
// End of frame: render Dear ImGui
|
||||
ImGui::Render();
|
||||
ImGui_ImplDX11_RenderDrawData(ImGui::GetDrawData());
|
||||
|
||||
// Swap
|
||||
g_pSwapChain->Present(1, 0);
|
||||
}
|
||||
|
||||
// Shutdown
|
||||
ImGui_ImplDX11_Shutdown();
|
||||
ImGui_ImplWin32_Shutdown();
|
||||
ImGui::DestroyContext();
|
||||
```
|
||||
|
||||
Please read 'PROGRAMMER GUIDE' in imgui.cpp for notes on how to setup Dear ImGui in your codebase.
|
||||
Please read the comments and instruction at the top of each file.
|
||||
Please read FAQ at http://www.dearimgui.com/faq
|
||||
|
||||
If you are using any of the backends provided here, you can add the backends/imgui_impl_xxxx(.cpp,.h)
|
||||
files to your project and use as-in. Each imgui_impl_xxxx.cpp file comes with its own individual
|
||||
Changelog, so if you want to update them later it will be easier to catch up with what changed.
|
||||
|
||||
|
||||

### Miscellaneous
|
||||
|
||||
**Building**
|
||||
|
||||
Unfortunately nowadays it is still tedious to create and maintain portable build files using external
|
||||
libraries (the kind we're using here to create a window and render 3D triangles) without relying on
|
||||
third party software and build systems. For most examples here we choose to provide:
|
||||
- Makefiles for Linux/OSX
|
||||
- Batch files for Visual Studio 2008+
|
||||
- A .sln project file for Visual Studio 2012+
|
||||
- Xcode project files for the Apple examples
|
||||
Please let us know if they don't work with your setup!
|
||||
You can probably just import the imgui_impl_xxx.cpp/.h files into your own codebase or compile those
|
||||
directly with a command-line compiler.
|
||||
|
||||
If you are interested in using Cmake to build and links examples, see:
|
||||
https://github.com/ocornut/imgui/pull/1713 and https://github.com/ocornut/imgui/pull/3027
|
||||
|
||||
**About mouse cursor latency**
|
||||
|
||||
Dear ImGui has no particular extra lag for most behaviors,
|
||||
e.g. the last value passed to 'io.AddMousePosEvent()' before NewFrame() will result in windows being moved
|
||||
to the right spot at the time of EndFrame()/Render(). At 60 FPS your experience should be pleasant.
|
||||
|
||||
However, consider that OS mouse cursors are typically drawn through a very specific hardware accelerated
|
||||
path and will feel smoother than the majority of contents rendered via regular graphics API (including,
|
||||
but not limited to Dear ImGui windows). Because UI rendering and interaction happens on the same plane
|
||||
as the mouse, that disconnect may be jarring to particularly sensitive users.
|
||||
You may experiment with enabling the io.MouseDrawCursor flag to request Dear ImGui to draw a mouse cursor
|
||||
using the regular graphics API, to help you visualize the difference between a "hardware" cursor and a
|
||||
regularly rendered software cursor.
|
||||
However, rendering a mouse cursor at 60 FPS will feel sluggish so you likely won't want to enable that at
|
||||
all times. It might be beneficial for the user experience to switch to a software rendered cursor _only_
|
||||
when an interactive drag is in progress.
|
||||
|
||||
Note that some setup or GPU drivers are likely to be causing extra display lag depending on their settings.
|
||||
If you feel that dragging windows feels laggy and you are not sure what the cause is: try to build a simple
|
||||
drawing a flat 2D shape directly under the mouse cursor!

# Q&A: Basics
|
||||
|
||||
### Q: Where is the documentation?
|
||||
|
||||
**This library is poorly documented at the moment and expects the user to be acquainted with C/C++.**
|
||||
- The [Wiki](https://github.com/ocornut/imgui/wiki) is a hub to many resources and links.
|
||||
- Handy [Getting Started](https://github.com/ocornut/imgui/wiki/Getting-Started) guide to integrate Dear ImGui in an existing application.
|
||||
- 20+ standalone example applications using e.g. OpenGL/DirectX are provided in the [examples/](https://github.com/ocornut/imgui/blob/master/examples/) folder to explain how to integrate Dear ImGui with your own engine/application. You can run those applications and explore them.
|
||||
- See demo code in [imgui_demo.cpp](https://github.com/ocornut/imgui/blob/master/imgui_demo.cpp) and particularly the `ImGui::ShowDemoWindow()` function. The demo covers most features of Dear ImGui, so you can read the code and see its output.
|
||||
- See documentation: [Backends](https://github.com/ocornut/imgui/blob/master/docs/BACKENDS.md), [Examples](https://github.com/ocornut/imgui/blob/master/docs/EXAMPLES.md), [Fonts](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md).
|
||||
- See documentation and comments at the top of [imgui.cpp](https://github.com/ocornut/imgui/blob/master/imgui.cpp) + general API comments in [imgui.h](https://github.com/ocornut/imgui/blob/master/imgui.h).
|
||||
- The [Glossary](https://github.com/ocornut/imgui/wiki/Glossary) page may be useful.
|
||||
- The [Issues](https://github.com/ocornut/imgui/issues) and [Discussions](https://github.com/ocornut/imgui/discussions) sections can be searched for past questions and issues.
|
||||
- Your programming IDE is your friend, find the type or function declaration to find comments associated with it.
|
||||
- The `ImGui::ShowMetricsWindow()` function exposes lots of internal information and tools. Although it is primarily designed as a debugging tool, having access to that information tends to help understands concepts.

### Q. What is this library called?
|
||||
|
||||
**This library is called Dear ImGui**. Please refer to it as Dear ImGui (not ImGui, not IMGUI).
|
||||
|
||||
(The library misleadingly started its life in 2014 as "ImGui" due to the fact that I didn't give it a proper name when I released 1.0, and had no particular expectation that it would take off. However, the term IMGUI (immediate-mode graphical user interface) was coined before and is being used in variety of other situations e.g. Unity uses it own implementation of the IMGUI paradigm. To reduce the ambiguity without affecting existing code bases, I have decided in December 2015 a fully qualified name "Dear ImGui" for this library.

|
||||
|
||||
### Q: Which version should I get?
|
||||
I occasionally tag [Releases](https://github.com/ocornut/imgui/releases) but it is generally safe and recommended to sync to master/latest. The library is fairly stable and regressions tend to be fixed fast when reported.
|
||||
|
||||
You may use the [docking](https://github.com/ocornut/imgui/tree/docking) branch which includes:
|
||||
- [Docking features](https://github.com/ocornut/imgui/issues/2109)
|
||||
- [Multi-viewport features](https://github.com/ocornut/imgui/issues/1542)
|
||||
|
||||
Many projects are using this branch and it is kept in sync with master regularly.

|

|
||||
### Q: How can I tell whether to dispatch mouse/keyboard to Dear ImGui or my application?
|
||||
|
||||
You can read the `io.WantCaptureMouse`, `io.WantCaptureKeyboard` and `io.WantTextInput` flags from the ImGuiIO structure.
|
||||
- When `io.WantCaptureMouse` is set, you need to discard/hide the mouse inputs from your underlying application.
|
||||
- When `io.WantCaptureKeyboard` is set, you need to discard/hide the keyboard inputs from your underlying application.
|
||||
- When `io.WantTextInput` is set, you can notify your OS/engine to popup an on-screen keyboard, if available (e.g. on a mobile phone, or console OS).
|
||||
|
||||
Important: you should always pass your mouse/keyboard inputs to Dear ImGui, regardless of the value `io.WantCaptureMouse`/`io.WantCaptureKeyboard`. This is because e.g. we need to detect that you clicked in the void to unfocus its own windows, and other reasons.
|
||||
|
||||
```cpp
|
||||
void MyLowLevelMouseButtonHandler(int button, bool down)
|
||||
{
|
||||
// (1) ALWAYS forward mouse data to ImGui! This is automatic with default backends. With your own backend:
|
||||
ImGuiIO& io = ImGui::GetIO();
|
||||
io.AddMouseButtonEvent(button, down);
|
||||
|
||||
// (2) ONLY forward mouse data to your underlying app/game.
|
||||
if (!io.WantCaptureMouse)
|
||||
my_game->HandleMouseData(...);
|
||||
}
|
||||
```
|
||||
|
||||
|
||||
**Note:** The `io.WantCaptureMouse` is more correct that any manual attempt to "check if the mouse is hovering a window" (don't do that!). It handles mouse dragging correctly (both dragging that started over your application or over a Dear ImGui window) and handle e.g. popup and modal windows blocking inputs.
|
||||
|
||||
**Note:** Those flags are updated by `ImGui::NewFrame()`. However it is generally more correct and easier that you poll flags from the previous frame, then submit your inputs, then call `NewFrame()`. If you attempt to do the opposite (which is generally harder) you are likely going to submit your inputs after `NewFrame()`, and therefore too late.
|
||||
|
||||
**Note:** If you are using a touch device, you may find use for an early call to `UpdateHoveredWindowAndCaptureFlags()` to correctly dispatch your initial touch. We will work on better out-of-the-box touch support in the future.
|
||||
|
||||
**Note:** Text input widget releases focus on the "KeyDown" event of the Return key, so the subsequent "KeyUp" event that your application receive will typically have `io.WantCaptureKeyboard == false`. Depending on your application logic it may or not be inconvenient to receive that KeyUp event. You might want to track which key-downs were targeted for Dear ImGui, e.g. with an array of bool, and filter out the corresponding key-ups.)

### Q: How can I enable keyboard or gamepad controls?
|
||||
- The gamepad/keyboard navigation is fairly functional and keeps being improved. The initial focus was to support game controllers, but keyboard is becoming increasingly and decently usable. Gamepad support is particularly useful to use Dear ImGui on a game console (e.g. PS4, Switch, XB1) without a mouse connected!
|
||||
- Keyboard: set `io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard` to enable.
|
||||
- Gamepad: set `io.ConfigFlags |= ImGuiConfigFlags_NavEnableGamepad` to enable (with a supporting backend).
|
||||
- See [Control Sheets for Gamepads](http://www.dearimgui.com/controls_sheets) (reference PNG/PSD for PS4, XB1, Switch gamepads).
|
||||
- See `USING GAMEPAD/KEYBOARD NAVIGATION CONTROLS` section of [imgui.cpp](https://github.com/ocornut/imgui/blob/master/imgui.cpp) for more details.

### Q: How can I use this on a machine without mouse, keyboard or screen? (input share, remote display)
|
||||
- You can share your computer mouse seamlessly with your console/tablet/phone using solutions such as [Synergy](https://symless.com/synergy)
|
||||
This is the preferred solution for developer productivity.
|
||||
In particular, the [micro-synergy-client repository](https://github.com/symless/micro-synergy-client) has simple
|
||||
and portable source code (uSynergy.c/.h) for a small embeddable client that you can use on any platform to connect
|
||||
to your host computer, based on the Synergy 1.x protocol. Make sure you download the Synergy 1 server on your computer.
|
||||
Console SDK also sometimes provide equivalent tooling or wrapper for Synergy-like protocols.
|
||||
- Game console users: consider emulating a mouse cursor with DualShock4 touch pad or a spare analog stick as a mouse-emulation fallback.
|
||||
- You may also use a third party solution such as [netImgui](https://github.com/sammyfreg/netImgui), [Remote ImGui](https://github.com/JordiRos/remoteimgui) or [imgui-ws](https://github.com/ggerganov/imgui-ws) which sends the vertices to render over the local network, allowing you to use Dear ImGui even on a screen-less machine. See [Wiki](https://github.com/ocornut/imgui/wiki) index for most details.
|
||||
- For touch inputs, you can increase the hit box of widgets (via the `style.TouchPadding` setting) to accommodate for the lack of precision of touch inputs, but it is recommended you use a mouse or gamepad to allow optimizing for screen real-estate and precision.

### Q: I integrated Dear ImGui in my engine and little squares are showing instead of text...
|
||||
Your renderer is not using the font texture correctly or it hasn't been uploaded to the GPU.
|
||||
- If this happens using the standard backends: A) have you modified the font atlas after `ImGui_ImplXXX_NewFrame()`? B) maybe the texture failed to upload, which could happens if for some reason your texture is too big. Also see [docs/FONTS.md](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md).
|
||||
- If this happens with a custom backend: make sure you have uploaded the font texture to the GPU, that all shaders are rendering states are setup properly (e.g. texture is bound). Compare your code to existing backends and use a graphics debugger such as [RenderDoc](https://renderdoc.org) to debug your rendering states.

### Q: I integrated Dear ImGui in my engine and some elements are clipping or disappearing when I move windows around...
|
||||
### Q: I integrated Dear ImGui in my engine and some elements are displaying outside their expected windows boundaries...
|
||||
You are probably mishandling the clipping rectangles in your render function.
|
||||
Each draw command needs the triangle rendered using the clipping rectangle provided in the ImDrawCmd structure (`ImDrawCmd->CllipRect`).
|
||||
Rectangles provided by Dear ImGui are defined as
|
||||
`(x1=left,y1=top,x2=right,y2=bottom)`
|
||||
and **NOT** as
|
||||
`(x1,y1,width,height)`.
|
||||
Refer to rendering backends in the [backends/](https://github.com/ocornut/imgui/tree/master/backends) folder for references of how to handle the `ClipRect` field.
|
||||
For example, the [DirectX11 backend](https://github.com/ocornut/imgui/blob/master/backends/imgui_impl_dx11.cpp) does this:
|
||||
```cpp
|
||||
// Project scissor/clipping rectangles into framebuffer space
|
||||
ImVec2 clip_off = draw_data->DisplayPos;
|
||||
ImVec2 clip_min(pcmd->ClipRect.x - clip_off.x, pcmd->ClipRect.y - clip_off.y);
|
||||
ImVec2 clip_max(pcmd->ClipRect.z - clip_off.x, pcmd->ClipRect.w - clip_off.y);
|
||||
if (clip_max.x <= clip_min.x || clip_max.y <= clip_min.y)
|
||||
continue;
|
||||
|
||||
// Apply scissor/clipping rectangle
|
||||
const D3D11_RECT r = { (LONG)clip_min.x, (LONG)clip_min.y, (LONG)clip_max.x, (LONG)clip_max.y };
|
||||
ctx->RSSetScissorRects(1, &r);
|

```

# Q&A: Usage
|
||||
|
||||
### Q: About the ID Stack system...
|
||||
### Q: Why is my widget not reacting when I click on it?
|
||||
### Q: How can I have widgets with an empty label?
|
||||
### Q: How can I have multiple widgets with the same label?
|
||||
### Q: How can I have multiple windows with the same label?
|
||||
|
||||
A primer on labels and the ID Stack...
|
||||
|
||||
Dear ImGui internally needs to uniquely identify UI elements.
|
||||
Elements that are typically not clickable (such as calls to the Text functions) don't need an ID.
|
||||
Interactive widgets (such as calls to Button buttons) need a unique ID.
|
||||
|
||||
**Unique IDs are used internally to track active widgets and occasionally associate state to widgets.<BR>
|
||||
Unique IDs are implicitly built from the hash of multiple elements that identify the "path" to the UI element.**
|
||||
|
||||
Since Dear ImGui 1.85, you can use `Demo>Tools>Stack Tool` or call `ImGui::ShowStackToolWindow()`. The tool display intermediate values leading to the creation of a unique ID, making things easier to debug and understand.
|
||||
|
||||
|
||||
|
||||
- Unique ID are often derived from a string label and at minimum scoped within their host window:
|
||||
```cpp
|
||||
Begin("MyWindow");
|
||||
Button("OK"); // Label = "OK", ID = hash of ("MyWindow", "OK")
|
||||
Button("Cancel"); // Label = "Cancel", ID = hash of ("MyWindow", "Cancel")
|
||||
End();
|
||||
```
|
||||
- Other elements such as tree nodes, etc. also pushes to the ID stack:
|
||||
```cpp
|
||||
Begin("MyWindow");
|
||||
if (TreeNode("MyTreeNode"))
|
||||
{
|
||||
Button("OK"); // Label = "OK", ID = hash of ("MyWindow", "MyTreeNode", "OK")
|
||||
TreePop();
|
||||
}
|
||||
End();
|
||||
```
|
||||
- Two items labeled "OK" in different windows or different tree locations won't collide:
|
||||
```cpp
|
||||
Begin("MyFirstWindow");
|
||||
Button("OK"); // Label = "OK", ID = hash of ("MyFirstWindow", "OK")
|
||||
End();
|
||||
Begin("MyOtherWindow");
|
||||
Button("OK"); // Label = "OK", ID = hash of ("MyOtherWindow", "OK")
|
||||
End();
|
||||
```
|
||||
|
||||
- If you have a same ID twice in the same location, you'll have a conflict:
|
||||
```cpp
|
||||
Begin("MyWindow");
|
||||
Button("OK");
|
||||
Button("OK"); // ERROR: ID collision with the first button! Interacting with either button will trigger the first one.
|
||||
Button(""); // ERROR: ID collision with Begin("MyWindow")!
|
||||
End();
|
||||
```
|
||||
Fear not! This is easy to solve and there are many ways to solve it!
|
||||
|
||||
- Solving ID conflict in a simple/local context:
|
||||
When passing a label you can optionally specify extra ID information within the string itself.
|
||||
Use "##" to pass a complement to the ID that won't be visible to the end-user.
|
||||
This helps solve the simple collision cases when you know e.g. at compilation time which items
|
||||
are going to be created:
|
||||
```cpp
|
||||
Begin("MyWindow");
|
||||
Button("Play"); // Label = "Play", ID = hash of ("MyWindow", "Play")
|
||||
Button("Play##foo1"); // Label = "Play", ID = hash of ("MyWindow", "Play##foo1") // Different from other buttons
|
||||
Button("Play##foo2"); // Label = "Play", ID = hash of ("MyWindow", "Play##foo2") // Different from other buttons
|
||||
Button("##foo"); // Label = "", ID = hash of ("MyWindow", "##foo") // Different from window
|
||||
End();
|
||||
```
|
||||
- If you want to completely hide the label, but still need an ID:
|
||||
```cpp
|
||||
Checkbox("##On", &b); // Label = "", ID = hash of (..., "##On") // No visible label, just a checkbox!
|
||||
```
|
||||
- Occasionally/rarely you might want to change a label while preserving a constant ID. This allows
|
||||
you to animate labels. For example, you may want to include varying information in a window title bar,
|
||||
but windows are uniquely identified by their ID. Use "###" to pass a label that isn't part of ID:
|
||||
```cpp
|
||||
Button("Hello###ID"); // Label = "Hello", ID = hash of (..., "###ID")
|
||||
Button("World###ID"); // Label = "World", ID = hash of (..., "###ID") // Same ID, different label
|
||||
|
||||
sprintf(buf, "My game (%f FPS)###MyGame", fps);
|
||||
Begin(buf); // Variable title, ID = hash of "MyGame"
|
||||
```
|
||||
- Solving ID conflict in a more general manner:
|
||||
Use `PushID()` / `PopID()` to create scopes and manipulate the ID stack, as to avoid ID conflicts
|
||||
within the same window. This is the most convenient way of distinguishing ID when iterating and
|
||||
creating many UI elements programmatically.
|
||||
You can push a pointer, a string, or an integer value into the ID stack.
|
||||
Remember that IDs are formed from the concatenation of _everything_ pushed into the ID stack.
|
||||
At each level of the stack, we store the seed used for items at this level of the ID stack.
|
||||
```cpp
|
||||
Begin("Window");
|
||||
for (int i = 0; i < 100; i++)
|
||||
{
|
||||
PushID(i); // Push i to the id tack
|
||||
Button("Click"); // Label = "Click", ID = hash of ("Window", i, "Click")
|
||||
PopID();
|
||||
}
|
||||
for (int i = 0; i < 100; i++)
|
||||
{
|
||||
MyObject* obj = Objects[i];
|
||||
PushID(obj);
|
||||
Button("Click"); // Label = "Click", ID = hash of ("Window", obj pointer, "Click")
|
||||
PopID();
|
||||
}
|
||||
for (int i = 0; i < 100; i++)
|
||||
{
|
||||
MyObject* obj = Objects[i];
|
||||
PushID(obj->Name);
|
||||
Button("Click"); // Label = "Click", ID = hash of ("Window", obj->Name, "Click")
|
||||
PopID();
|
||||
}
|
||||
End();
|
||||
```
|
||||
- You can stack multiple prefixes into the ID stack:
|
||||
```cpp
|
||||
Button("Click"); // Label = "Click", ID = hash of (..., "Click")
|
||||
PushID("node");
|
||||
Button("Click"); // Label = "Click", ID = hash of (..., "node", "Click")
|
||||
PushID(my_ptr);
|
||||
Button("Click"); // Label = "Click", ID = hash of (..., "node", my_ptr, "Click")
|
||||
PopID();
|
||||
PopID();
|
||||
```
|
||||
- Tree nodes implicitly create a scope for you by calling `PushID()`:
|
||||
```cpp
|
||||
Button("Click"); // Label = "Click", ID = hash of (..., "Click")
|
||||
if (TreeNode("node")) // <-- this function call will do a PushID() for you (unless instructed not to, with a special flag)
|
||||
{
|
||||
Button("Click"); // Label = "Click", ID = hash of (..., "node", "Click")
|
||||
TreePop();
|
||||
}
|
||||
```
|
||||
|
||||
When working with trees, IDs are used to preserve the open/close state of each tree node.
|
||||
Depending on your use cases you may want to use strings, indices, or pointers as ID.
|
||||
- e.g. when following a single pointer that may change over time, using a static string as ID
|
||||
will preserve your node open/closed state when the targeted object change.
|
||||
- e.g. when displaying a list of objects, using indices or pointers as ID will preserve the
|
||||
node open/closed state differently. See what makes more sense in your situation!

### Q: How can I display an image? What is ImTextureID, how does it work?
|
||||
|
||||
Short explanation:
|
||||
- Refer to [Image Loading and Displaying Examples](https://github.com/ocornut/imgui/wiki/Image-Loading-and-Displaying-Examples) on the [Wiki](https://github.com/ocornut/imgui/wiki).
|
||||
- You may use functions such as `ImGui::Image()`, `ImGui::ImageButton()` or lower-level `ImDrawList::AddImage()` to emit draw calls that will use your own textures.
|
||||
- Actual textures are identified in a way that is up to the user/engine. Those identifiers are stored and passed as ImTextureID (void*) value.
|
||||
- Loading image files from the disk and turning them into a texture is not within the scope of Dear ImGui (for a good reason).
|
||||
|
||||
**Please read documentations or tutorials on your graphics API to understand how to display textures on the screen before moving onward.**
|
||||
|
||||
Long explanation:
|
||||
- Dear ImGui's job is to create "meshes", defined in a renderer-agnostic format made of draw commands and vertices. At the end of the frame, those meshes (ImDrawList) will be displayed by your rendering function. They are made up of textured polygons and the code to render them is generally fairly short (a few dozen lines). In the examples/ folder, we provide functions for popular graphics APIs (OpenGL, DirectX, etc.).
|
||||
- Each rendering function decides on a data type to represent "textures". The concept of what is a "texture" is entirely tied to your underlying engine/graphics API.
|
||||
We carry the information to identify a "texture" in the ImTextureID type.
|
||||
ImTextureID is nothing more than a void*, aka 4/8 bytes worth of data: just enough to store one pointer or integer of your choice.
|
||||
Dear ImGui doesn't know or understand what you are storing in ImTextureID, it merely passes ImTextureID values until they reach your rendering function.
|
||||
- In the [examples/](https://github.com/ocornut/imgui/tree/master/examples) backends, for each graphics API we decided on a type that is likely to be a good representation for specifying an image from the end-user perspective. This is what the _examples_ rendering functions are using:
|
||||
```cpp
|
||||
OpenGL:
|
||||
- ImTextureID = GLuint
|
||||
- See ImGui_ImplOpenGL3_RenderDrawData() function in imgui_impl_opengl3.cpp
|
||||
```
|
||||
```cpp
|
||||
DirectX9:
|
||||
- ImTextureID = LPDIRECT3DTEXTURE9
|
||||
- See ImGui_ImplDX9_RenderDrawData() function in imgui_impl_dx9.cpp
|
||||
```
|
||||
```cpp
|
||||
DirectX11:
|
||||
- ImTextureID = ID3D11ShaderResourceView*
|
||||
- See ImGui_ImplDX11_RenderDrawData() function in imgui_impl_dx11.cpp
|
||||
```
|
||||
```cpp
|
||||
DirectX12:
|
||||
- ImTextureID = D3D12_GPU_DESCRIPTOR_HANDLE
|
||||
- See ImGui_ImplDX12_RenderDrawData() function in imgui_impl_dx12.cpp
|
||||
```
|
||||
For example, in the OpenGL example backend we store raw OpenGL texture identifier (GLuint) inside ImTextureID.
|
||||
Whereas in the DirectX11 example backend we store a pointer to ID3D11ShaderResourceView inside ImTextureID, which is a higher-level structure tying together both the texture and information about its format and how to read it.
|
||||
|
||||
- If you have a custom engine built over e.g. OpenGL, instead of passing GLuint around you may decide to use a high-level data type to carry information about the texture as well as how to display it (shaders, etc.). The decision of what to use as ImTextureID can always be made better by knowing how your codebase is designed. If your engine has high-level data types for "textures" and "material" then you may want to use them.
|
||||
If you are starting with OpenGL or DirectX or Vulkan and haven't built much of a rendering engine over them, keeping the default ImTextureID representation suggested by the example backends is probably the best choice.
|
||||
(Advanced users may also decide to keep a low-level type in ImTextureID, use ImDrawList callback and pass information to their renderer)
|
||||
|
||||
User code may do:
|
||||
```cpp
|
||||
// Cast our texture type to ImTextureID / void*
|
||||
MyTexture* texture = g_CoffeeTableTexture;
|
||||
ImGui::Image((void*)texture, ImVec2(texture->Width, texture->Height));
|
||||
```
|
||||
The renderer function called after ImGui::Render() will receive that same value that the user code passed:
|
||||
```cpp
|
||||
// Cast ImTextureID / void* stored in the draw command as our texture type
|
||||
MyTexture* texture = (MyTexture*)pcmd->GetTexID();
|
||||
MyEngineBindTexture2D(texture);
|
||||
```
|
||||
Once you understand this design, you will understand that loading image files and turning them into displayable textures is not within the scope of Dear ImGui.
|
||||
This is by design and is a good thing because it means your code has full control over your data types and how you display them.
|
||||
If you want to display an image file (e.g. PNG file) on the screen, please refer to documentation and tutorials for the graphics API you are using.
|
||||
|
||||
Refer to [Image Loading and Displaying Examples](https://github.com/ocornut/imgui/wiki/Image-Loading-and-Displaying-Examples) on the [Wiki](https://github.com/ocornut/imgui/wiki) to find simplified examples for loading textures with OpenGL, DirectX9 and DirectX11.
|
||||
|
||||
C/C++ tip: a void* is pointer-sized storage. You may safely store any pointer or integer into it by casting your value to ImTextureID / void*, and vice-versa.
|
||||
Because both end-points (user code and rendering function) are under your control, you know exactly what is stored inside the ImTextureID / void*.
|
||||
Here are some examples:
|
||||
```cpp
|
||||
GLuint my_tex = XXX;
|
||||
void* my_void_ptr;
|
||||
my_void_ptr = (void*)(intptr_t)my_tex; // cast a GLuint into a void* (we don't take its address! we literally store the value inside the pointer)
|
||||
my_tex = (GLuint)(intptr_t)my_void_ptr; // cast a void* into a GLuint
|
||||
|
||||
ID3D11ShaderResourceView* my_dx11_srv = XXX;
|
||||
void* my_void_ptr;
|
||||
my_void_ptr = (void*)my_dx11_srv; // cast a ID3D11ShaderResourceView* into an opaque void*
|
||||
my_dx11_srv = (ID3D11ShaderResourceView*)my_void_ptr; // cast a void* into a ID3D11ShaderResourceView*
|
||||
```
|
||||
Finally, you may call `ImGui::ShowMetricsWindow()` to explore/visualize/understand how the ImDrawList are generated.

### Q: How can I use maths operators with ImVec2?
|
||||
|
||||
We do not export maths operators by default in imgui.h in order to not conflict with the use of your own maths types and maths operators. As a convenience, you may use `#defne IMGUI_DEFINE_MATH_OPERATORS` + `#include "imgui.h"` to access our basic maths operators.

|

|

### Q: How can I use my own maths types instead of ImVec2/ImVec4?
|
||||
|
||||
You can setup your [imconfig.h](https://github.com/ocornut/imgui/blob/master/imconfig.h) file with `IM_VEC2_CLASS_EXTRA`/`IM_VEC4_CLASS_EXTRA` macros to add implicit type conversions to our own maths types.
|
||||
This way you will be able to use your own types everywhere, e.g. passing `MyVector2` or `glm::vec2` to ImGui functions instead of `ImVec2`.
|
||||
|

|
||||
|
||||
### Q: How can I interact with standard C++ types (such as std::string and std::vector)?
|
||||
- Being highly portable (backends/bindings for several languages, frameworks, programming styles, obscure or older platforms/compilers), and aiming for compatibility & performance suitable for every modern real-time game engine, Dear ImGui does not use any of std C++ types. We use raw types (e.g. char* instead of std::string) because they adapt to more use cases.
|
||||
- To use ImGui::InputText() with a std::string or any resizable string class, see [misc/cpp/imgui_stdlib.h](https://github.com/ocornut/imgui/blob/master/misc/cpp/imgui_stdlib.h).
|
||||
- To use combo boxes and list boxes with `std::vector` or any other data structure: the `BeginCombo()/EndCombo()` API
|
||||
lets you iterate and submit items yourself, so does the `ListBoxHeader()/ListBoxFooter()` API.
|
||||
Prefer using them over the old and awkward `Combo()/ListBox()` api.
|
||||
- Generally for most high-level types you should be able to access the underlying data type.
|
||||
You may write your own one-liner wrappers to facilitate user code (tip: add new functions in ImGui:: namespace from your code).
|
||||
- Dear ImGui applications often need to make intensive use of strings. It is expected that many of the strings you will pass
|
||||
to the API are raw literals (free in C/C++) or allocated in a manner that won't incur a large cost on your application.
|
||||
Please bear in mind that using `std::string` on applications with a large amount of UI may incur unsatisfactory performances.
|
||||
Modern implementations of `std::string` often include small-string optimization (which is often a local buffer) but those
|
||||
are not configurable and not the same across implementations.
|
||||
- If you are finding your UI traversal cost to be too large, make sure your string usage is not leading to an excessive amount
|
||||
of heap allocations. Consider using literals, statically sized buffers, and your own helper functions. A common pattern
|
||||
is that you will need to build lots of strings on the fly, and their maximum length can be easily scoped ahead.
|
||||
One possible implementation of a helper to facilitate printf-style building of strings: https://github.com/ocornut/Str
|
||||
This is a small helper where you can instance strings with configurable local buffers length. Many game engines will
|
||||
provide similar or better string helpers.

### Q: How can I display custom shapes? (using low-level ImDrawList API)
|
||||
|
||||
- You can use the low-level `ImDrawList` api to render shapes within a window.
|
||||
```cpp
|
||||
ImGui::Begin("My shapes");
|
||||
|
||||
ImDrawList* draw_list = ImGui::GetWindowDrawList();
|
||||
|
||||
// Get the current ImGui cursor position
|
||||
ImVec2 p = ImGui::GetCursorScreenPos();
|
||||
|
||||
// Draw a red circle
|
||||
draw_list->AddCircleFilled(ImVec2(p.x + 50, p.y + 50), 30.0f, IM_COL32(255, 0, 0, 255));
|
||||
|
||||
// Draw a 3 pixel thick yellow line
|
||||
draw_list->AddLine(ImVec2(p.x, p.y), ImVec2(p.x + 100.0f, p.y + 100.0f), IM_COL32(255, 255, 0, 255), 3.0f);
|
||||
|
||||
// Advance the ImGui cursor to claim space in the window (otherwise the window will appear small and needs to be resized)
|
||||
ImGui::Dummy(ImVec2(200, 200));
|
||||
|
||||
ImGui::End();
|
||||
```
|
||||
|
||||
|
||||
- Refer to "Demo > Examples > Custom Rendering" in the demo window and read the code of `ShowExampleAppCustomRendering()` in `imgui_demo.cpp` from more examples.
|
||||
- To generate colors: you can use the macro `IM_COL32(255,255,255,255)` to generate them at compile time, or use `ImGui::GetColorU32(IM_COL32(255,255,255,255))` or `ImGui::GetColorU32(ImVec4(1.0f,1.0f,1.0f,1.0f))` to generate a color that is multiplied by the current value of `style.Alpha`.
|
||||
- Math operators: if you have setup `IM_VEC2_CLASS_EXTRA` in `imconfig.h` to bind your own math types, you can use your own math types and their natural operators instead of ImVec2. ImVec2 by default doesn't export any math operators in the public API. You may use `#define IMGUI_DEFINE_MATH_OPERATORS` `#include "imgui.h"` to use our math operators, but instead prefer using your own math library and set it up in `imconfig.h`.
|
||||
- You can use `ImGui::GetBackgroundDrawList()` or `ImGui::GetForegroundDrawList()` to access draw lists which will be displayed behind and over every other Dear ImGui window (one bg/fg drawlist per viewport). This is very convenient if you need to quickly display something on the screen that is not associated with a Dear ImGui window.
|
||||
- You can also create your own empty window and draw inside it. Call Begin() with the NoBackground | NoDecoration | NoSavedSettings | NoInputs flags (The `ImGuiWindowFlags_NoDecoration` flag itself is a shortcut for NoTitleBar | NoResize | NoScrollbar | NoCollapse). Then you can retrieve the ImDrawList* via `GetWindowDrawList()` and draw to it in any way you like.
|
||||
- You can create your own ImDrawList instance. You'll need to initialize them with `ImGui::GetDrawListSharedData()`, or create your own instancing `ImDrawListSharedData`, and then call your renderer function with your own ImDrawList or ImDrawData data.
|
||||
- Looking for fun? The [ImDrawList coding party 2020](https://github.com/ocornut/imgui/issues/3606) thread is full of "don't do this at home" extreme uses of the ImDrawList API.

# Q&A: Fonts, Text
|
||||
|
||||
### Q: How should I handle DPI in my application?
|
||||
|
||||
The short answer is: obtain the desired DPI scale, load your fonts resized with that scale (always round down fonts size to the nearest integer), and scale your Style structure accordingly using `style.ScaleAllSizes()`.
|
||||
|
||||
Your application may want to detect DPI change and reload the fonts and reset style between frames.
|
||||
|
||||
Your ui code should avoid using hardcoded constants for size and positioning. Prefer to express values as multiple of reference values such as `ImGui::GetFontSize()` or `ImGui::GetFrameHeight()`. So e.g. instead of seeing a hardcoded height of 500 for a given item/window, you may want to use `30*ImGui::GetFontSize()` instead.
|
||||
|
||||
Down the line Dear ImGui will provide a variety of standardized reference values to facilitate using this.
|
||||
|
||||
Applications in the `examples/` folder are not DPI aware partly because they are unable to load a custom font from the file-system (may change that in the future).
|
||||
|
||||
The reason DPI is not auto-magically solved in stock examples is that we don't yet have a satisfying solution for the "multi-dpi" problem (using the `docking` branch: when multiple viewport windows are over multiple monitors using different DPI scales). The current way to handle this on the application side is:
|
||||
- Create and maintain one font atlas per active DPI scale (e.g. by iterating `platform_io.Monitors[]` before `NewFrame()`).
|
||||
- Hook `platform_io.OnChangedViewport()` to detect when a `Begin()` call makes a Dear ImGui window change monitor (and therefore DPI).
|
||||
- In the hook: swap atlas, swap style with correctly sized one, and remap the current font from one atlas to the other (you may need to maintain a remapping table of your fonts at varying DPI scales).
|
||||
|
||||
This approach is relatively easy and functional but comes with two issues:
|
||||
- It's not possibly to reliably size or position a window ahead of `Begin()` without knowing on which monitor it'll land.
|
||||
- Style override may be lost during the `Begin()` call crossing monitor boundaries. You may need to do some custom scaling mumbo-jumbo if you want your `OnChangedViewport()` handler to preserve style overrides.
|
||||
|
||||
Please note that if you are not using multi-viewports with multi-monitors using different DPI scales, you can ignore that and use the simpler technique recommended at the top.
|
||||
|
||||
On Windows, in addition to scaling the font size (make sure to round to an integer) and using `style.ScaleAllSizes()`, you will need to inform Windows that your application is DPI aware. If this is not done, Windows will scale the application window and the UI text will be blurry. Potential solutions to indicate DPI awareness on Windows are:
|
||||
|
||||
- For SDL: the flag `SDL_WINDOW_ALLOW_HIGHDPI` needs to be passed to `SDL_CreateWindow()``.
|
||||
- For GLFW: this is done automatically.
|
||||
- For other Windows projects with other backends, or wrapper projects:
|
||||
- We provide a `ImGui_ImplWin32_EnableDpiAwareness()` helper method in the Win32 backend.
|
||||
- Use an [application manifest file](https://learn.microsoft.com/en-us/windows/win32/hidpi/setting-the-default-dpi-awareness-for-a-process) to set the `<dpiAware>` property.
|
||||
|
||||
### Q: How can I load a different font than the default?
|
||||
Use the font atlas to load the TTF/OTF file you want:
|
||||
|
||||
```cpp
|
||||
ImGuiIO& io = ImGui::GetIO();
|
||||
io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels);
|
||||
io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
|
||||
```
|
||||
|
||||
Default is ProggyClean.ttf, monospace, rendered at size 13, embedded in dear imgui's source code.
|
||||
|
||||
(Tip: monospace fonts are convenient because they allow to facilitate horizontal alignment directly at the string level.)
|
||||
|
||||
(Read the [docs/FONTS.md](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md) file for more details about font loading.)
|
||||
|
||||
New programmers: remember that in C/C++ and most programming languages if you want to use a
|
||||
backslash \ within a string literal, you need to write it double backslash "\\":
|
||||
|
||||
```cpp
|
||||
io.Fonts->AddFontFromFileTTF("MyFolder\MyFont.ttf", size); // WRONG (you are escaping the M here!)
|
||||
io.Fonts->AddFontFromFileTTF("MyFolder\\MyFont.ttf", size); // CORRECT (Windows only)
|
||||
io.Fonts->AddFontFromFileTTF("MyFolder/MyFont.ttf", size); // ALSO CORRECT
|
||||
```

|
||||
### Q: How can I easily use icons in my application?
|
||||
The most convenient and practical way is to merge an icon font such as FontAwesome inside your
|
||||
main font. Then you can refer to icons within your strings.
|
||||
You may want to see `ImFontConfig::GlyphMinAdvanceX` to make your icon look monospace to facilitate alignment.
|
||||
(Read the [docs/FONTS.md](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md) file for more details about icons font loading.)
|
||||
With some extra effort, you may use colorful icons by registering custom rectangle space inside the font atlas,
|
||||
and copying your own graphics data into it. See docs/FONTS.md about using the AddCustomRectFontGlyph API.

|

|
||||
### Q: How can I load multiple fonts?
|
||||
Use the font atlas to pack them into a single texture:
|
||||
(Read the [docs/FONTS.md](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md) file and the code in ImFontAtlas for more details.)
|
||||
|
||||
```cpp
|
||||
ImGuiIO& io = ImGui::GetIO();
|
||||
ImFont* font0 = io.Fonts->AddFontDefault();
|
||||
ImFont* font1 = io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels);
|
||||
ImFont* font2 = io.Fonts->AddFontFromFileTTF("myfontfile2.ttf", size_in_pixels);
|
||||
io.Fonts->GetTexDataAsRGBA32() or GetTexDataAsAlpha8()
|
||||
// the first loaded font gets used by default
|
||||
// use ImGui::PushFont()/ImGui::PopFont() to change the font at runtime
|
||||
|
||||
// Options
|
||||
ImFontConfig config;
|
||||
config.OversampleH = 2;
|
||||
config.OversampleV = 1;
|
||||
config.GlyphOffset.y -= 1.0f; // Move everything by 1 pixel up
|
||||
config.GlyphExtraSpacing.x = 1.0f; // Increase spacing between characters
|
||||
io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_pixels, &config);
|
||||
|
||||
// Combine multiple fonts into one (e.g. for icon fonts)
|
||||
static ImWchar ranges[] = { 0xf000, 0xf3ff, 0 };
|
||||
ImFontConfig config;
|
||||
config.MergeMode = true;
|
||||
io.Fonts->AddFontDefault();
|
||||
io.Fonts->AddFontFromFileTTF("fontawesome-webfont.ttf", 16.0f, &config, ranges); // Merge icon font
|
||||
io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_pixels, nullptr, &config, io.Fonts->GetGlyphRangesJapanese()); // Merge japanese glyphs
|
||||
```

|
||||
|
||||
### Q: How can I display and input non-Latin characters such as Chinese, Japanese, Korean, Cyrillic?
|
||||
When loading a font, pass custom Unicode ranges to specify the glyphs to load.
|
||||
|
||||
```cpp
|
||||
// Add default Japanese ranges
|
||||
io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, nullptr, io.Fonts->GetGlyphRangesJapanese());
|
||||
|
||||
// Or create your own custom ranges (e.g. for a game you can feed your entire game script and only build the characters the game need)
|
||||
ImVector<ImWchar> ranges;
|
||||
ImFontGlyphRangesBuilder builder;
|
||||
builder.AddText("Hello world"); // Add a string (here "Hello world" contains 7 unique characters)
|
||||
builder.AddChar(0x7262); // Add a specific character
|
||||
builder.AddRanges(io.Fonts->GetGlyphRangesJapanese()); // Add one of the default ranges
|
||||
builder.BuildRanges(&ranges); // Build the final result (ordered ranges with all the unique characters submitted)
|
||||
io.Fonts->AddFontFromFileTTF("myfontfile.ttf", 16.0f, nullptr, ranges.Data);
|
||||
```
|
||||
|
||||
All your strings need to use UTF-8 encoding.
|
||||
You need to tell your compiler to use UTF-8, or in C++11 you can encode a string literal in UTF-8 by using the u8"hello" syntax.
|
||||
Specifying literal in your source code using a local code page (such as CP-923 for Japanese or CP-1251 for Cyrillic) will NOT work!
|
||||
See [About UTF-8 Encoding](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md#about-utf-8-encoding) section
|
||||
of [FONTS.md](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md) for details about UTF-8 Encoding.
|
||||
|
||||
Text input: it is up to your application to pass the right character code by calling `io.AddInputCharacter()`.
|
||||
The applications in examples/ are doing that.
|
||||
Windows: you can use the WM_CHAR or WM_UNICHAR or WM_IME_CHAR message (depending if your app is built using Unicode or MultiByte mode).
|
||||
You may also use `MultiByteToWideChar()` or `ToUnicode()` to retrieve Unicode codepoints from MultiByte characters or keyboard state.
|
||||
Windows: if your language is relying on an Input Method Editor (IME), you can write your HWND to ImGui::GetMainViewport()->PlatformHandleRaw
|
||||
for the default implementation of io.SetPlatformImeDataFn() to set your Microsoft IME position correctly.

### Q: Can you create elaborate/serious tools with Dear ImGui?
|
||||
|
||||
Yes. People have written game editors, data browsers, debuggers, profilers, and all sorts of non-trivial tools with the library. In my experience, the simplicity of the API is very empowering. Your UI runs close to your live data. Make the tools always-on and everybody in the team will be inclined to create new tools (as opposed to more "offline" UI toolkits where only a fraction of your team effectively creates tools). The list of sponsors below is also an indicator that serious game teams have been using the library.
|
||||
|
||||
Dear ImGui is very programmer centric and the immediate-mode GUI paradigm might require you to readjust some habits before you can realize its full potential. Dear ImGui is about making things that are simple, efficient, and powerful.
|
||||
|
||||
Dear ImGui is built to be efficient and scalable toward the needs for AAA-quality applications running all day. The IMGUI paradigm offers different opportunities for optimization than the more typical RMGUI paradigm.

|

### Q: Can you reskin the look of Dear ImGui?
|
||||
|
||||
Somewhat. You can alter the look of the interface to some degree: changing colors, sizes, padding, rounding, and fonts. However, as Dear ImGui is designed and optimized to create debug tools, the amount of skinning you can apply is limited. There is only so much you can stray away from the default look and feel of the interface. Dear ImGui is NOT designed to create a user interface for games, although with ingenious use of the low-level API you can do it.
|
||||
|
||||
A reasonably skinned application may look like (screenshot from [#2529](https://github.com/ocornut/imgui/issues/2529#issuecomment-524281119)):

|

|
||||
### Q: Why using C++ (as opposed to C)?
|
||||
|
||||
Dear ImGui takes advantage of a few C++ language features for convenience but nothing anywhere Boost insanity/quagmire. Dear ImGui doesn't use any C++ header file. Dear ImGui uses a very small subset of C++11 features. In particular, function overloading and default parameters are used to make the API easier to use and code terser. Doing so I believe the API is sitting on a sweet spot and giving up on those features would make the API more cumbersome. Other features such as namespace, constructors, and templates (in the case of the ImVector<> class) are also relied on as a convenience.
|
||||
|
||||
There is an auto-generated [c-api for Dear ImGui (cimgui)](https://github.com/cimgui/cimgui) by Sonoro1234 and Stephan Dilly. It is designed for creating bindings to other languages. If possible, I would suggest using your target language functionalities to try replicating the function overloading and default parameters used in C++ else the API may be harder to use. Also see [Bindings](https://github.com/ocornut/imgui/wiki/Bindings) for various third-party bindings.

|
||||
|
||||
### Q: How can I help?
|
||||
- Businesses: please reach out to `contact AT dearimgui.com` if you work in a place using Dear ImGui! We can discuss ways for your company to fund development via invoiced technical support, maintenance, or sponsoring contacts. This is among the most useful thing you can do for Dear ImGui. With increased funding, we can hire more people to work on this project.
|
||||
- Individuals: you can support continued maintenance and development via PayPal donations. See [README](https://github.com/ocornut/imgui/blob/master/docs/README.md).
|
||||
- If you are experienced with Dear ImGui and C++, look at [GitHub Issues](https://github.com/ocornut/imgui/issues), [GitHub Discussions](https://github.com/ocornut/imgui/discussions), the [Wiki](https://github.com/ocornut/imgui/wiki), read [docs/TODO.txt](https://github.com/ocornut/imgui/blob/master/docs/TODO.txt), and see how you want to help and can help!
|
||||
- Disclose your usage of Dear ImGui via a dev blog post, a tweet, a screenshot, a mention somewhere, etc.
|
||||
You may post screenshots or links in the [gallery threads](https://github.com/ocornut/imgui/issues/6478). Visuals are ideal as they inspire other programmers. Disclosing your use of Dear ImGui helps the library grow credibility, and helps other teams and programmers with taking decisions.
|

## Dear ImGui: Using Fonts
|
||||
|
||||
The code in imgui.cpp embeds a copy of 'ProggyClean.ttf' (by Tristan Grimmer),
|
||||
a 13 pixels high, pixel-perfect font used by default. We embed it in the source code so you can use Dear ImGui without any file system access. ProggyClean does not scale smoothly, therefore it is recommended that you load your own file when using Dear ImGui in an application aiming to look nice and wanting to support multiple resolutions.
|
||||
|
||||
You may also load external .TTF/.OTF files.
|
||||
In the [misc/fonts/](https://github.com/ocornut/imgui/tree/master/misc/fonts) folder you can find a few suggested fonts, provided as a convenience.
|
||||

---------------------------------------
|
||||
|
||||
## Readme First
|
||||
|
||||
**A vast majority of font and text related issues encountered comes from 3 things:**
|
||||
- Invalid filename due to use of `\` or unexpected working directory. See [About Filenames](#about-filenames). AddFontXXX functions should assert if the filename is incorrect.
|
||||
- Invalid UTF-8 encoding of your non-ASCII strings. See [About UTF-8 Encoding](#about-utf-8-encoding). Use the encoding viewer to confirm yours is correct.
|
||||
- You need to load a font with explicit glyph ranges if you want to use non-ASCII characters. See [Fonts Loading Instructions](#fonts-loading-instructions). Use Metrics/Debugger->Fonts to confirm loaded fonts and loaded glyph ranges.
|
||||
|
||||
The third point is a current constraint of Dear ImGui (which we will lift in the future): when loading a font you need to specify which characters glyphs to load.
|
||||
All loaded fonts glyphs are rendered into a single texture atlas ahead of time. Calling either of `io.Fonts->GetTexDataAsAlpha8()`, `io.Fonts->GetTexDataAsRGBA32()` or `io.Fonts->Build()` will build the atlas. This is generally called by the Renderer backend, e.g. `ImGui_ImplDX11_NewFrame()` calls it.
|
||||
|
||||
**If you use custom glyphs ranges, make sure the array is persistent** and available during the calls to `GetTexDataAsAlpha8()/GetTexDataAsRGBA32()/Build()`.
|
||||
|
||||
##### [Return to Index](#index)
|
||||
|
||||
## About Filenames
|
||||
|
||||
**Please note that many new C/C++ users have issues loading their files _because the filename they provide is wrong_ due to incorrect assumption of what is the current directory.**
|
||||
|
||||
Two things to watch for:
|
||||
|
||||
(1) In C/C++ and most programming languages if you want to use a backslash `\` within a string literal, you need to write it double backslash `\\`. At it happens, Windows uses backslashes as a path separator, so be mindful.
|
||||
```cpp
|
||||
io.Fonts->AddFontFromFileTTF("MyFiles\MyImage01.jpg", ...); // This is INCORRECT!!
|
||||
io.Fonts->AddFontFromFileTTF("MyFiles\\MyImage01.jpg", ...); // This is CORRECT
|
||||
```
|
||||
In some situations, you may also use `/` path separator under Windows.
|
||||
|
||||
(2) Make sure your IDE/debugger settings starts your executable from the right working (current) directory. In Visual Studio you can change your working directory in project `Properties > General > Debugging > Working Directory`. People assume that their execution will start from the root folder of the project, where by default it often starts from the folder where object or executable files are stored.
|
||||
```cpp
|
||||
io.Fonts->AddFontFromFileTTF("MyImage01.jpg", ...); // Relative filename depends on your Working Directory when running your program!
|
||||
io.Fonts->AddFontFromFileTTF("../MyImage01.jpg", ...); // Load from the parent folder of your Working Directory
|
||||
```

||||

## About UTF-8 Encoding
|
||||
|
||||
**For non-ASCII characters display, a common user issue is not passing correctly UTF-8 encoded strings.**
|
||||
|
||||
(1) We provide a function `ImGui::DebugTextEncoding(const char* text)` which you can call to verify the content of your UTF-8 strings.
|
||||
This is a convenient way to confirm that your encoding is correct.
|
||||
|
||||
```cpp
|
||||
ImGui::SeparatorText("CORRECT");
|
||||
ImGui::DebugTextEncoding(u8"こんにちは");
|
||||
|
||||
ImGui::SeparatorText("INCORRECT");
|
||||
ImGui::DebugTextEncoding("こんにちは");
|
||||
```
|
||||
|
||||
|
||||
You can also find this tool under `Metrics/Debuggers->Tools->UTF-8 Encoding viewer` if you want to paste from clipboard, but this won't validate the UTF-8 encoding done by your compiler.
|
||||
|
||||
(2) To encode in UTF-8:
|
||||
|
||||
There are also compiler-specific ways to enforce UTF-8 encoding by default:
|
||||
|
||||
- Visual Studio compiler: `/utf-8` command-line flag.
|
||||
- Visual Studio compiler: `#pragma execution_character_set("utf-8")` inside your code.
|
||||
- Since May 2023 we have changed the Visual Studio projects of all our examples to use `/utf-8` ([see commit](https://github.com/ocornut/imgui/commit/513af1efc9080857bbd10000d98f98f2a0c96803)).
|
||||
|
||||
Or, since C++11, you can use the `u8"my text"` syntax to encode literal strings as UTF-8. e.g.:
|
||||
```cpp
|
||||
ImGui::Text(u8"hello");
|
||||
ImGui::Text(u8"こんにちは"); // this will always be encoded as UTF-8
|
||||
ImGui::Text("こんにちは"); // the encoding of this is depending on compiler settings/flags and may be incorrect.
|
||||
```
|
||||
|
||||
Since C++20, because the C++ committee hate its users, they decided to change the `u8""` syntax to not return `const char*` but a new type `const char_t*` which doesn't cast to `const char*`.
|
||||
Because of type usage of `u8""` in C++20 is a little more tedious:
|
||||
```cpp
|
||||
ImGui::Text((const char*)u8"こんにちは");
|
||||
```
|
||||
We suggest using a macro in your codebase:
|
||||
```cpp
|
||||
#define U8(_S) (const char*)u8##_S
|
||||
ImGui::Text(U8("こんにちは"));
|
||||
```

|

## Debug Tools
|
||||
|
||||
#### Metrics/Debugger->Fonts
|
||||
You can use the `Metrics/Debugger` window (available in `Demo>Tools`) to browse your fonts and understand what's going on if you have an issue. You can also reach it in `Demo->Tools->Style Editor->Fonts`. The same information are also available in the Style Editor under Fonts.
|
||||
|
||||
|
||||
|
||||
#### UTF-8 Encoding Viewer**
|
||||
You can use the `UTF-8 Encoding viewer` in `Metrics/Debugger` to verify the content of your UTF-8 strings. From C/C++ code, you can call `ImGui::DebugTextEncoding("my string");` function to verify that your UTF-8 encoding is correct.
|

## Fonts Loading Instructions
|
||||
|
||||
**Load default font:**
|
||||
```cpp
|
||||
ImGuiIO& io = ImGui::GetIO();
|
||||
io.Fonts->AddFontDefault();
|
||||
```
|
||||
|
||||
**Load .TTF/.OTF file with:**
|
||||
```cpp
|
||||
ImGuiIO& io = ImGui::GetIO();
|
||||
io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels);
|
||||
```
|
||||
If you get an assert stating "Could not load font file!", your font filename is likely incorrect. Read "[About filenames](#about-filenames)" carefully.
|
||||
|
||||
**Load multiple fonts:**
|
||||
```cpp
|
||||
// Init
|
||||
ImGuiIO& io = ImGui::GetIO();
|
||||
ImFont* font1 = io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels);
|
||||
ImFont* font2 = io.Fonts->AddFontFromFileTTF("anotherfont.otf", size_pixels);
|
||||
```
|
||||
```cpp
|
||||
// In application loop: select font at runtime
|
||||
ImGui::Text("Hello"); // use the default font (which is the first loaded font)
|
||||
ImGui::PushFont(font2);
|
||||
ImGui::Text("Hello with another font");
|
||||
ImGui::PopFont();
|
||||
```
|
||||
|
||||
**For advanced options create a ImFontConfig structure and pass it to the AddFont() function (it will be copied internally):**
|
||||
```cpp
|
||||
ImFontConfig config;
|
||||
config.OversampleH = 2;
|
||||
config.OversampleV = 1;
|
||||
config.GlyphExtraSpacing.x = 1.0f;
|
||||
ImFont* font = io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, &config);
|
||||
```
|
||||
|
||||
**Combine multiple fonts into one:**
|
||||
```cpp
|
||||
// Load a first font
|
||||
ImFont* font = io.Fonts->AddFontDefault();
|
||||
|
||||
// Add character ranges and merge into the previous font
|
||||
// The ranges array is not copied by the AddFont* functions and is used lazily
|
||||
// so ensure it is available at the time of building or calling GetTexDataAsRGBA32().
|
||||
static const ImWchar icons_ranges[] = { 0xf000, 0xf3ff, 0 }; // Will not be copied by AddFont* so keep in scope.
|
||||
ImFontConfig config;
|
||||
config.MergeMode = true;
|
||||
io.Fonts->AddFontFromFileTTF("DroidSans.ttf", 18.0f, &config, io.Fonts->GetGlyphRangesJapanese()); // Merge into first font
|
||||
io.Fonts->AddFontFromFileTTF("fontawesome-webfont.ttf", 18.0f, &config, icons_ranges); // Merge into first font
|
||||
io.Fonts->Build();
|
||||
```
|
||||
|
||||
**Add a fourth parameter to bake specific font ranges only:**
|
||||
|
||||
```cpp
|
||||
// Basic Latin, Extended Latin
|
||||
io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, nullptr, io.Fonts->GetGlyphRangesDefault());
|
||||
|
||||
// Default + Selection of 2500 Ideographs used by Simplified Chinese
|
||||
io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, nullptr, io.Fonts->GetGlyphRangesChineseSimplifiedCommon());
|
||||
|
||||
// Default + Hiragana, Katakana, Half-Width, Selection of 1946 Ideographs
|
||||
io.Fonts->AddFontFromFileTTF("font.ttf", size_pixels, nullptr, io.Fonts->GetGlyphRangesJapanese());
|
||||
```
|
||||
See [Using Custom Glyph Ranges](#using-custom-glyph-ranges) section to create your own ranges.
|
||||
|
||||
|
||||
**Example loading and using a Japanese font:**
|
||||
|
||||
```cpp
|
||||
ImGuiIO& io = ImGui::GetIO();
|
||||
io.Fonts->AddFontFromFileTTF("NotoSansCJKjp-Medium.otf", 20.0f, nullptr, io.Fonts->GetGlyphRangesJapanese());
|
||||
```
|
||||
```cpp
|
||||
ImGui::Text(u8"こんにちは！テスト %d", 123);
|
||||
if (ImGui::Button(u8"ロード"))
|
||||
{
|
||||
// do stuff
|
||||
}
|
||||
ImGui::InputText("string", buf, IM_ARRAYSIZE(buf));
|
||||
ImGui::SliderFloat("float", &f, 0.0f, 1.0f);
|
||||
```
|
||||
|
||||
|
||||
<br>_(settings: Dark style (left), Light style (right) / Font: NotoSansCJKjp-Medium, 20px / Rounding: 5)_
|
||||
|
||||
**Font Atlas too large?**
|
||||
|
||||
- If you have very large number of glyphs or multiple fonts, the texture may become too big for your graphics API. The typical result of failing to upload a texture is if every glyph appears as a white rectangle.
|
||||
- Mind the fact that some graphics drivers have texture size limitation. If you are building a PC application, mind the fact that your users may use hardware with lower limitations than yours.
|
||||
|
||||
Some solutions:
|
||||
|
||||
1. Reduce glyphs ranges by calculating them from source localization data.
|
||||
You can use the `ImFontGlyphRangesBuilder` for this purpose and rebuilding your atlas between frames when new characters are needed. This will be the biggest win!
|
||||
2. You may reduce oversampling, e.g. `font_config.OversampleH = 2`, this will largely reduce your texture size.
|
||||
Note that while OversampleH = 2 looks visibly very close to 3 in most situations, with OversampleH = 1 the quality drop will be noticeable.
|
||||
3. Set `io.Fonts.TexDesiredWidth` to specify a texture width to minimize texture height (see comment in `ImFontAtlas::Build()` function).
|
||||
4. Set `io.Fonts.Flags |= ImFontAtlasFlags_NoPowerOfTwoHeight;` to disable rounding the texture height to the next power of two.
|
||||
5. Read about oversampling [here](https://github.com/nothings/stb/blob/master/tests/oversample).
|
||||
6. To support the extended range of unicode beyond 0xFFFF (e.g. emoticons, dingbats, symbols, shapes, ancient languages, etc...) add `#define IMGUI_USE_WCHAR32`in your `imconfig.h`.

## Using Icon Fonts
|
||||
|
||||
Using an icon font (such as [FontAwesome](http://fontawesome.io) or [OpenFontIcons](https://github.com/traverseda/OpenFontIcons)) is an easy and practical way to use icons in your Dear ImGui application.
|
||||
A common pattern is to merge the icon font within your main font, so you can embed icons directly from your strings without having to change fonts back and forth.
|
||||
|
||||
To refer to the icon UTF-8 codepoints from your C++ code, you may use those headers files created by Juliette Foucaut: https://github.com/juliettef/IconFontCppHeaders.
|
||||
|
||||
So you can use `ICON_FA_SEARCH` as a string that will render as a "Search" icon.
|
||||
|
||||
Example Setup:
|
||||
```cpp
|
||||
// Merge icons into default tool font
|
||||
#include "IconsFontAwesome.h"
|
||||
ImGuiIO& io = ImGui::GetIO();
|
||||
io.Fonts->AddFontDefault();
|
||||
|
||||
ImFontConfig config;
|
||||
config.MergeMode = true;
|
||||
config.GlyphMinAdvanceX = 13.0f; // Use if you want to make the icon monospaced
|
||||
static const ImWchar icon_ranges[] = { ICON_MIN_FA, ICON_MAX_FA, 0 };
|
||||
io.Fonts->AddFontFromFileTTF("fonts/fontawesome-webfont.ttf", 13.0f, &config, icon_ranges);
|
||||
```
|
||||
Example Usage:
|
||||
```cpp
|
||||
// Usage, e.g.
|
||||
ImGui::Text("%s among %d items", ICON_FA_SEARCH, count);
|
||||
ImGui::Button(ICON_FA_SEARCH " Search");
|
||||
// C string _literals_ can be concatenated at compilation time, e.g. "hello" " world"
|
||||
// ICON_FA_SEARCH is defined as a string literal so this is the same as "A" "B" becoming "AB"
|
||||
```
|
||||
See Links below for other icons fonts and related tools.
|
||||
|
||||
Here's an application using icons ("Avoyd", https://www.avoyd.com):

## Using FreeType Rasterizer (imgui_freetype)
|
||||
|
||||
- Dear ImGui uses imstb\_truetype.h to rasterize fonts (with optional oversampling). This technique and its implementation are not ideal for fonts rendered at small sizes, which may appear a little blurry or hard to read.
|
||||
- There is an implementation of the ImFontAtlas builder using FreeType that you can use in the [misc/freetype/](https://github.com/ocornut/imgui/tree/master/misc/freetype) folder.
|
||||
- FreeType supports auto-hinting which tends to improve the readability of small fonts.
|
||||
- Read documentation in the [misc/freetype/](https://github.com/ocornut/imgui/tree/master/misc/freetype) folder.
|
||||
- Correct sRGB space blending will have an important effect on your font rendering quality.
|
||||
|
||||
##### [Return to Index](#index)
|
||||
|
||||
## Using Colorful Glyphs/Emojis
|
||||
|
||||
- Rendering of colored emojis is only supported by imgui_freetype with FreeType 2.10+.
|
||||
- You will need to load fonts with the `ImGuiFreeTypeBuilderFlags_LoadColor` flag.
|
||||
- Emojis are frequently encoded in upper Unicode layers (character codes >0x10000) and will need dear imgui compiled with `IMGUI_USE_WCHAR32`.
|
||||
- Not all types of color fonts are supported by FreeType at the moment.
|
||||
- Stateful Unicode features such as skin tone modifiers are not supported by the text renderer.
|
||||
|
||||
|
||||
|
||||
```cpp
|
||||
io.Fonts->AddFontFromFileTTF("../../../imgui_dev/data/fonts/NotoSans-Regular.ttf", 16.0f);
|
||||
static ImWchar ranges[] = { 0x1, 0x1FFFF, 0 };
|
||||
static ImFontConfig cfg;
|
||||
cfg.OversampleH = cfg.OversampleV = 1;
|
||||
cfg.MergeMode = true;
|
||||
cfg.FontBuilderFlags |= ImGuiFreeTypeBuilderFlags_LoadColor;
|
||||
io.Fonts->AddFontFromFileTTF("C:\\Windows\\Fonts\\seguiemj.ttf", 16.0f, &cfg, ranges);
|
||||
```

|
||||
|
||||
## Using Custom Glyph Ranges
|
||||
|
||||
You can use the `ImFontGlyphRangesBuilder` helper to create glyph ranges based on text input. For example: for a game where your script is known, if you can feed your entire script to it and only build the characters the game needs.
|
||||
```cpp
|
||||
ImVector<ImWchar> ranges;
|
||||
ImFontGlyphRangesBuilder builder;
|
||||
builder.AddText("Hello world"); // Add a string (here "Hello world" contains 7 unique characters)
|
||||
builder.AddChar(0x7262); // Add a specific character
|
||||
builder.AddRanges(io.Fonts->GetGlyphRangesJapanese()); // Add one of the default ranges
|
||||
builder.BuildRanges(&ranges); // Build the final result (ordered ranges with all the unique characters submitted)
|
||||
|
||||
io.Fonts->AddFontFromFileTTF("myfontfile.ttf", size_in_pixels, nullptr, ranges.Data);
|
||||
io.Fonts->Build(); // Build the atlas while 'ranges' is still in scope and not deleted.
|
||||
```
|
||||

|
||||
|
||||
## Using Custom Colorful Icons
|
||||
|
||||
As an alternative to rendering colorful glyphs using imgui_freetype with `ImGuiFreeTypeBuilderFlags_LoadColor`, you may allocate your own space in the texture atlas and write yourself into it. **(This is a BETA api, use if you are familiar with dear imgui and with your rendering backend)**
|
||||
|
||||
- You can use the `ImFontAtlas::AddCustomRect()` and `ImFontAtlas::AddCustomRectFontGlyph()` api to register rectangles that will be packed into the font atlas texture. Register them before building the atlas, then call Build()`.
|
||||
- You can then use `ImFontAtlas::GetCustomRectByIndex(int)` to query the position/size of your rectangle within the texture, and blit/copy any graphics data of your choice into those rectangles.
|
||||
- This API is beta because it is likely to change in order to support multi-dpi (multiple viewports on multiple monitors with varying DPI scale).
|
||||
|
||||
#### Pseudo-code:
|
||||
```cpp
|
||||
// Add font, then register two custom 13x13 rectangles mapped to glyph 'a' and 'b' of this font
|
||||
ImFont* font = io.Fonts->AddFontDefault();
|
||||
int rect_ids[2];
|
||||
rect_ids[0] = io.Fonts->AddCustomRectFontGlyph(font, 'a', 13, 13, 13+1);
|
||||
rect_ids[1] = io.Fonts->AddCustomRectFontGlyph(font, 'b', 13, 13, 13+1);
|
||||
|
||||
// Build atlas
|
||||
io.Fonts->Build();
|
||||
|
||||
// Retrieve texture in RGBA format
|
||||
unsigned char* tex_pixels = nullptr;
|
||||
int tex_width, tex_height;
|
||||
io.Fonts->GetTexDataAsRGBA32(&tex_pixels, &tex_width, &tex_height);
|
||||
|
||||
for (int rect_n = 0; rect_n < IM_ARRAYSIZE(rect_ids); rect_n++)
|
||||
{
|
||||
int rect_id = rect_ids[rect_n];
|
||||
if (const ImFontAtlasCustomRect* rect = io.Fonts->GetCustomRectByIndex(rect_id))
|
||||
{
|
||||
// Fill the custom rectangle with red pixels (in reality you would draw/copy your bitmap data here!)
|
||||
for (int y = 0; y < rect->Height; y++)
|
||||
{
|
||||
ImU32* p = (ImU32*)tex_pixels + (rect->Y + y) * tex_width + (rect->X);
|
||||
for (int x = rect->Width; x > 0; x--)
|
||||
*p++ = IM_COL32(255, 0, 0, 255);
|
||||
}
|
||||
}
|
||||
}

||||

## Using Font Data Embedded In Source Code
|
||||
|
||||
- Compile and use [binary_to_compressed_c.cpp](https://github.com/ocornut/imgui/blob/master/misc/fonts/binary_to_compressed_c.cpp) to create a compressed C style array that you can embed in source code.
|
||||
- See the documentation in [binary_to_compressed_c.cpp](https://github.com/ocornut/imgui/blob/master/misc/fonts/binary_to_compressed_c.cpp) for instructions on how to use the tool.
|
||||
- You may find a precompiled version binary_to_compressed_c.exe for Windows inside the demo binaries package (see [README](https://github.com/ocornut/imgui/blob/master/docs/README.md)).
|
||||
- The tool can optionally output Base85 encoding to reduce the size of _source code_ but the read-only arrays in the actual binary will be about 20% bigger.
|
||||
|
||||
Then load the font with:
|
||||
```cpp
|
||||
ImFont* font = io.Fonts->AddFontFromMemoryCompressedTTF(compressed_data, compressed_data_size, size_pixels, ...);
|
||||
```
|
||||
or
|
||||
```cpp
|
||||
ImFont* font = io.Fonts->AddFontFromMemoryCompressedBase85TTF(compressed_data_base85, size_pixels, ...);
|
||||
```

|
||||
|
||||
### The Pitch
|
||||
|
||||
Dear ImGui is a **bloat-free graphical user interface library for C++**. It outputs optimized vertex buffers that you can render anytime in your 3D-pipeline-enabled application. It is fast, portable, renderer agnostic, and self-contained (no external dependencies).
|
||||
|
||||
Dear ImGui is designed to **enable fast iterations** and to **empower programmers** to create **content creation tools and visualization / debug tools** (as opposed to UI for the average end-user). It favors simplicity and productivity toward this goal and lacks certain features commonly found in more high-level libraries.
|
||||
|
||||
Dear ImGui is particularly suited to integration in game engines (for tooling), real-time 3D applications, fullscreen applications, embedded applications, or any applications on console platforms where operating system features are non-standard.
|
||||
|
||||
- Minimize state synchronization.
|
||||
- Minimize state storage on user side.
|
||||
- Minimize setup and maintenance.
|
||||
- Easy to use to create dynamic UI which are the reflection of a dynamic data set.
|
||||
- Easy to use to create code-driven and data-driven tools.
|
||||
- Easy to use to create ad hoc short-lived tools and long-lived, more elaborate tools.
|
||||
- Easy to hack and improve.
|
||||
- Portable, minimize dependencies, run on target (consoles, phones, etc.).
|
||||
- Efficient runtime and memory consumption.
|
||||
- Battle-tested, used by [many major actors in the game industry](https://github.com/ocornut/imgui/wiki/Software-using-dear-imgui).
|
||||
|
||||
### Usage
|
||||
|
||||
**The core of Dear ImGui is self-contained within a few platform-agnostic files** which you can easily compile in your application/engine. They are all the files in the root folder of the repository (imgui*.cpp, imgui*.h). **No specific build process is required**. You can add the .cpp files into your existing project. See [Getting Started](https://github.com/ocornut/imgui/wiki/Getting-Started).
|
||||
|
||||
**Backends for a variety of graphics API and rendering platforms** are provided in the [backends/](https://github.com/ocornut/imgui/tree/master/backends) folder, along with example applications in the [examples/](https://github.com/ocornut/imgui/tree/master/examples) folder. See the [Integration](#integration) section of this document for details. You may also create your own backend. Anywhere where you can render textured triangles, you can render Dear ImGui.
|
||||
|
||||
After Dear ImGui is set up in your application, you can use it from \_anywhere\_ in your program loop:
|
||||
```cpp
|
||||
ImGui::Text("Hello, world %d", 123);
|
||||
if (ImGui::Button("Save"))
|
||||
MySaveFunction();
|
||||
ImGui::InputText("string", buf, IM_ARRAYSIZE(buf));
|
||||
ImGui::SliderFloat("float", &f, 0.0f, 1.0f);
|
||||
```
|
||||
|
||||
|
||||
|
||||
```cpp
|
||||
// Create a window called "My First Tool", with a menu bar.
|
||||
ImGui::Begin("My First Tool", &my_tool_active, ImGuiWindowFlags_MenuBar);
|
||||
if (ImGui::BeginMenuBar())
|
||||
{
|
||||
if (ImGui::BeginMenu("File"))
|
||||
{
|
||||
if (ImGui::MenuItem("Open..", "Ctrl+O")) { /* Do stuff */ }
|
||||
if (ImGui::MenuItem("Save", "Ctrl+S")) { /* Do stuff */ }
|
||||
if (ImGui::MenuItem("Close", "Ctrl+W")) { my_tool_active = false; }
|
||||
ImGui::EndMenu();
|
||||
}
|
||||
ImGui::EndMenuBar();
|
||||
}
|
||||
|
||||
// Edit a color stored as 4 floats
|
||||
ImGui::ColorEdit4("Color", my_color);
|
||||
|
||||
// Generate samples and plot them
|
||||
float samples[100];
|
||||
for (int n = 0; n < 100; n++)
|
||||
samples[n] = sinf(n * 0.2f + ImGui::GetTime() * 1.5f);
|
||||
ImGui::PlotLines("Samples", samples, 100);
|
||||
|
||||
// Display contents in a scrolling region
|
||||
ImGui::TextColored(ImVec4(1,1,0,1), "Important Stuff");
|
||||
ImGui::BeginChild("Scrolling");
|
||||
for (int n = 0; n < 50; n++)
|
||||
ImGui::Text("%04d: Some text", n);
|
||||
ImGui::EndChild();
|
||||
ImGui::End();
|
||||
```
|
||||
|
||||
|
||||
Dear ImGui allows you to **create elaborate tools** as well as very short-lived ones. On the extreme side of short-livedness: using the Edit&Continue (hot code reload) feature of modern compilers you can add a few widgets to tweak variables while your application is running, and remove the code a minute later! Dear ImGui is not just for tweaking values. You can use it to trace a running algorithm by just emitting text commands. You can use it along with your own reflection data to browse your dataset live. You can use it to expose the internals of a subsystem in your engine, to create a logger, an inspection tool, a profiler, a debugger, an entire game-making editor/framework, etc.
|
||||
|
||||
### How it works
|
||||
|
||||
The IMGUI paradigm through its API tries to minimize superfluous state duplication, state synchronization, and state retention from the user's point of view. It is less error-prone (less code and fewer bugs) than traditional retained-mode interfaces, and lends itself to creating dynamic user interfaces. Check out the Wiki's [About the IMGUI paradigm](https://github.com/ocornut/imgui/wiki#about-the-imgui-paradigm) section for more details.
|
||||
|
||||
Dear ImGui outputs vertex buffers and command lists that you can easily render in your application. The number of draw calls and state changes required to render them is fairly small. Because Dear ImGui doesn't know or touch graphics state directly, you can call its functions anywhere in your code (e.g. in the middle of a running algorithm, or in the middle of your own rendering process). Refer to the sample applications in the examples/ folder for instructions on how to integrate Dear ImGui with your existing codebase.
|
||||
|
||||
_A common misunderstanding is to mistake immediate mode GUI for immediate mode rendering, which usually implies hammering your driver/GPU with a bunch of inefficient draw calls and state changes as the GUI functions are called. This is NOT what Dear ImGui does. Dear ImGui outputs vertex buffers and a small list of draw calls batches. It never touches your GPU directly. The draw call batches are decently optimal and you can render them later, in your app or even remotely._
|
||||
|
||||
### Releases & Changelogs
|
||||
|
||||
See [Releases](https://github.com/ocornut/imgui/releases) page for decorated Changelogs.
|
||||
Reading the changelogs is a good way to keep up to date with the things Dear ImGui has to offer, and maybe will give you ideas of some features that you've been ignoring until now!
|
||||
|
||||
### Demo
|
||||
|
||||
Calling the `ImGui::ShowDemoWindow()` function will create a demo window showcasing a variety of features and examples. The code is always available for reference in `imgui_demo.cpp`. [Here's how the demo looks](https://raw.githubusercontent.com/wiki/ocornut/imgui/web/v167/v167-misc.png).
|
||||
|
||||
You should be able to build the examples from sources. If you don't, let us know! If you want to have a quick look at some Dear ImGui features, you can download Windows binaries of the demo app here:
|
||||
- [imgui-demo-binaries-20230704.zip](https://www.dearimgui.com/binaries/imgui-demo-binaries-20230704.zip) (Windows, 1.89.7, built 2023/07/04, master) or [older binaries](https://www.dearimgui.com/binaries).
|
||||
|
||||
The demo applications are not DPI aware so expect some blurriness on a 4K screen. For DPI awareness in your application, you can load/reload your font at a different scale and scale your style with `style.ScaleAllSizes()` (see [FAQ](https://www.dearimgui.com/faq)).
|
||||
|
||||
### Integration
|
||||
|
||||
On most platforms and when using C++, **you should be able to use a combination of the [imgui_impl_xxxx](https://github.com/ocornut/imgui/tree/master/backends) backends without modification** (e.g. `imgui_impl_win32.cpp` + `imgui_impl_dx11.cpp`). If your engine supports multiple platforms, consider using more imgui_impl_xxxx files instead of rewriting them: this will be less work for you, and you can get Dear ImGui running immediately. You can _later_ decide to rewrite a custom backend using your custom engine functions if you wish so.
|
||||
|
||||
See [Getting Started](https://github.com/ocornut/imgui/wiki/Getting-Started). Integrating Dear ImGui within your custom engine is a matter of 1) wiring mouse/keyboard/gamepad inputs 2) uploading a texture to your GPU/render engine 3) providing a render function that can bind textures and render textured triangles, which is essentially what Backends are doing. The [examples/](https://github.com/ocornut/imgui/tree/master/examples) folder is populated with applications doing just that: setting up a window and using backends. If you follow [Getting Started](https://github.com/ocornut/imgui/wiki/Getting-Started) it should in theory takes you less than an hour to integrate Dear ImGui. **Make sure to spend time reading the [FAQ](https://www.dearimgui.com/faq), comments, and the examples applications!**

**Which version should I get?**
|
||||
|
||||
We occasionally tag [Releases](https://github.com/ocornut/imgui/releases) (with nice releases notes) but it is generally safe and recommended to sync to latest `master` or `docking` branch. The library is fairly stable and regressions tend to be fixed fast when reported. Advanced users may want to use the `docking` branch with [Multi-Viewport](https://github.com/ocornut/imgui/issues/1542) and [Docking](https://github.com/ocornut/imgui/issues/2109) features. This branch is kept in sync with master regularly.

Omar: "I first discovered the IMGUI paradigm at [Q-Games](https://www.q-games.com) where Atman Binstock had dropped his own simple implementation in the codebase, which I spent quite some time improving and thinking about. It turned out that Atman was exposed to the concept directly by working with Casey. When I moved to Media Molecule I rewrote a new library trying to overcome the flaws and limitations of the first one I've worked with. It became this library and since then I have spent an unreasonable amount of time iterating and improving it."

ISSUES & TODO LIST
|
||||
|
||||
Issue numbers (#) refer to GitHub issues listed at https://github.com/ocornut/imgui/issues/XXXX
|
||||
THIS LIST IS NOT WELL MAINTAINED. MOST OF THE WORK HAPPENS ON GITHUB NOWADAYS.
|
||||
The list below consist mostly of ideas noted down before they are requested/discussed by users (at which point they usually exist on the github issue tracker).
|
||||
It's mostly a bunch of personal notes, probably incomplete. Feel free to query if you have any questions.
|
||||
|
||||
- doc: add a proper documentation system (maybe relying on automation? #435)
|
||||
- doc: checklist app to verify backends/integration of imgui (test inputs, rendering, callback, etc.).
|
||||
- doc/tips: tips of the day: website? applet in imgui_club?
|
||||
- doc/wiki: work on the wiki https://github.com/ocornut/imgui/wiki
|
||||
|
||||
- window: preserve/restore relative focus ordering (persistent or not), and e.g. of multiple reappearing windows (#2304) -> also see docking reference to same #.
|
||||
- window: calling SetNextWindowSize() every frame with <= 0 doesn't do anything, may be useful to allow (particularly when used for a single axis). (#690)
|
||||
- window: add a way for very transient windows (non-saved, temporary overlay over hundreds of objects) to "clean" up from the global window list. perhaps a lightweight explicit cleanup pass.
|
||||
- window: auto-fit feedback loop when user relies on any dynamic layout (window width multiplier, column) appears weird to end-user. clarify.
|
||||
- window: begin with *p_open == false could return false.
|
||||
- window: get size/pos helpers given names (see discussion in #249)
|
||||
- window: when window is very small, prioritize resize button over close button.
|
||||
- window: double-clicking on title bar to minimize isn't consistent interaction, perhaps move to single-click on left-most collapse icon?
|
||||
- window: expose contents size. (#1045)
|
||||
- window: using SetWindowPos() inside Begin() and moving the window with the mouse reacts a very ugly glitch. We should just defer the SetWindowPos() call.
|
||||
- window: GetWindowSize() returns (0,0) when not calculated? (#1045)
|
||||
- window: investigate better auto-positioning for new windows.
|
||||
- window: top most window flag? more z-order contrl? (#2574)
|
||||
- window/size: manually triggered auto-fit (double-click on grip) shouldn't resize window down to viewport size?
|
||||
- window/size: how to allow to e.g. auto-size vertically to fit contents, but be horizontally resizable? Assuming SetNextWindowSize() is modified to treat -1.0f on each axis as "keep as-is" (would be good but might break erroneous code): Problem is UpdateWindowManualResize() and lots of code treat (window->AutoFitFramesX > 0 || window->AutoFitFramesY > 0) together.
|
||||
- window/opt: freeze window flag: if not focused/hovered, return false, render with previous ImDrawList. and/or reduce refresh rate. -> this may require enforcing that it is illegal to submit contents if Begin returns false.
|
||||
- window/child: background options for child windows, border option (disable rounding).
|
||||
- window/child: allow resizing of child windows (possibly given min/max for each axis?.)
|
||||
- window/child: allow SetNextWindowContentSize() to work on child windows.
|
||||
- window/clipping: some form of clipping when DisplaySize (or corresponding viewport) is zero.
|
||||
- window/tabbing: add a way to signify that a window or docked window requires attention (e.g. blinking title bar, trying to click behind a modal).
|
||||
- window/id_stack: add e.g. window->GetIDFromPath() with support for leading / and ../ (#1390, #331) -> model from test engine.
|
||||
! scrolling: exposing horizontal scrolling with Shift+Wheel even when scrollbar is disabled expose lots of issues (#2424, #1463)
|
||||
- scrolling: while holding down a scrollbar, try to keep the same contents visible (at least while not moving mouse)
|
||||
- scrolling: allow immediately effective change of scroll after Begin() if we haven't appended items yet.
|
||||
- scrolling: forward mouse wheel scrolling to parent window when at the edge of scrolling limits? (useful for listbox,tables?)
|
||||
- scrolling/style: shadows on scrollable areas to denote that there is more contents (see e.g. DaVinci Resolve ui)
|
||||
|
||||
- drawdata: make it easy to deep-copy (or swap?) a full ImDrawData so user can easily save that data if they use threaded rendering. (e.g. #2646)
|
||||
! drawlist: add CalcTextSize() func to facilitate consistent code from user pov (currently need to use ImGui or ImFont alternatives!)
|
||||
- drawlist: maintaining bounding box per command would allow to merge draw command when clipping isn't relied on (typical non-scrolling window or non-overflowing column would merge with previous command). (WIP branch)
|
||||
- drawlist: make it easier to toggle AA per primitive, so we can use e.g. non-AA fill + AA borders more naturally
|
||||
- drawlist: non-AA strokes have gaps between points (#593, #288), glitch especially on RenderCheckmark() and ColorPicker4().
|
||||
- drawlist: callback: add an extra void* in ImDrawCallback to allow passing render-local data to the callback (would break API).
|
||||
- drawlist: AddRect vs AddLine position confusing (#2441)
|
||||
- drawlist/opt: store rounded corners in texture to use 1 quad per corner (filled and wireframe) to lower the cost of rounding. (#1962)
|
||||
- drawlist/opt: AddRect() axis aligned pixel aligned (no-aa) could use 8 triangles instead of 16 and no normal calculation.
|
||||
- drawlist/opt: thick AA line could be doable in same number of triangles as 1.0 AA line by storing gradient+full color in atlas.
|
||||
|
||||
- items: IsItemHovered() info stored in a stack? so that 'if TreeNode() { Text; TreePop; } if IsHovered' return the hover state of the TreeNode?
|
||||
|
||||
- widgets: display mode: widget-label, label-widget (aligned on column or using fixed size), label-newline-tab-widget etc. (#395)
|
||||
- widgets: clean up widgets internal toward exposing everything and stabilizing imgui_internals.h.
|
||||
- widgets: add always-allow-overlap mode. This should perhaps be the default? one problem is that highlight after mouse-wheel scrolling gets deferred, makes scrolling more flickery.
|
||||
- widgets: start exposing PushItemFlag() and ImGuiItemFlags
|
||||
- widgets: alignment options in style (e.g. center Selectable, Right-Align within Button, etc.) #1260
|
||||
- widgets: activate by identifier (trigger button, focus given id)
|
||||
- widgets: custom glyph/shapes replacements for stock sapes. (also #6090 #2431 #2235 #6517)
|
||||
- widgets: coloredit: keep reporting as active when picker is on?
|
||||
- widgets: group/scalarn functions: expose more per-component information. e.g. store NextItemData.ComponentIdx set by scalarn function, groups can expose them back somehow.
|
||||
- selectable: using (size.x == 0.0f) and (SelectableTextAlign.x > 0.0f) followed by SameLine() is currently not supported.
|
||||
- selectable: generic BeginSelectable()/EndSelectable() mechanism. (work out alongside range-select branch)
|
||||
- selectable: a way to visualize partial/mixed selection (e.g. parent tree node has children with mixed selection)
|
||||
|
||||
- input text: clean up the mess caused by converting UTF-8 <> wchar. the code is rather inefficient right now and super fragile. (WIP branch)
|
||||
- input text: preserve scrolling when unfocused?
|
||||
- input text: reorganize event handling, allow CharFilter to modify buffers, allow multiple events? (#541)
|
||||
- input text: expose CursorPos in char filter event (#816)
|
||||
- input text: try usage idiom of using InputText with data only exposed through get/set accessors, without extraneous copy/alloc. (#3009)
|
||||
- input text: access public fields via a non-callback API e.g. InputTextGetState("xxx") that may return nullptr if not active (available in internals)
|
||||
- input text: flag to disable live update of the user buffer (also applies to float/int text input) (#701)
|
||||
- input text: hover tooltip could show unclamped text
|
||||
- input text: support for INSERT key to toggle overwrite mode. currently disabled because stb_textedit behavior is unsatisfactory on multi-line. (#2863)
|
||||
- input text: option to Tab after an Enter validation.
|
||||
- input text: add ImGuiInputTextFlags_EnterToApply? (off #218)
|
||||
- input text: easier ways to update buffer (from source char*) while owned. preserve some sort of cursor position for multi-line text.
|
||||
- input text: add discard flag (e.g. ImGuiInputTextFlags_DiscardActiveBuffer) or make it easier to clear active focus for text replacement during edition (#725)
|
||||
- input text: display bug when clicking a drag/slider after an input text in a different window has all-selected text (order dependent). actually a very old bug but no one appears to have noticed it.
|
||||
- input text: allow centering/positioning text so that ctrl+clicking Drag or Slider keeps the textual value at the same pixel position.
|
||||
- input text: decorrelate display layout from inputs with custom template - e.g. what's the easiest way to implement a nice IP/Mac address input editor?
|
||||
- input text: global callback system so user can plug in an expression evaluator easily. (#1691)
|
||||
- input text: force scroll to end or scroll to a given line/contents (so user can implement a log or a search feature)
|
||||
- input text: a way to preview completion (e.g. disabled text completing from the cursor)
|
||||
- input text: a side bar that could e.g. preview where errors are. probably left to the user to draw but we'd need to give them the info there.
|
||||
- input text: a way for the user to provide syntax coloring.
|
||||
- input text: Shift+TAB with ImGuiInputTextFlags_AllowTabInput could eat preceding blanks, up to tab_count.
|
||||
- input text multi-line: don't directly call AddText() which does an unnecessary vertex reserve for character count prior to clipping. and/or more line-based clipping to AddText(). and/or reorganize TextUnformatted/RenderText for more efficiency for large text (e.g TextUnformatted could clip and log separately, etc).
|
||||
- input text multi-line: support for copy/cut without selection (copy/cut current line?)
|
||||
- input text multi-line: line numbers? status bar? (follow up on #200)
|
||||
- input text multi-line: behave better when user changes input buffer while editing is active (even though it is illegal behavior). namely, the change of buffer can create a scrollbar glitch (#725)
|
||||
- input text multi-line: better horizontal scrolling support (#383, #1224)
|
||||
- input text multi-line: single call to AddText() should be coarse clipped on InputTextEx() end.
|
||||
- input number: optional range min/max for Input*() functions
|
||||
- input number: holding [-]/[+] buttons could increase the step speed non-linearly (or user-controlled)
|
||||
- input number: use mouse wheel to step up/down
|
||||
|
||||
- layout: helper or a way to express ImGui::SameLine(ImGui::GetCursorStartPos().x + ImGui::CalcItemWidth() + ImGui::GetStyle().ItemInnerSpacing.x); in a simpler manner.
|
||||
- layout, font: horizontal tab support, A) text mode: forward only tabs (e.g. every 4 characters/N pixels from pos x1), B) manual mode: explicit tab stops acting as mini columns, no clipping (for menu items, many kind of uses, also vaguely relate to #267, #395)
|
||||
- layout: horizontal layout helper (#97)
|
||||
- layout: horizontal flow until no space left (#404)
|
||||
- layout: more generic alignment state (left/right/centered) for single items?
|
||||
- layout: clean up the InputFloatN/SliderFloatN/ColorEdit4 layout code. item width should include frame padding.
|
||||
- layout: vertical alignment of mixed height items (e.g. buttons) within a same line (#1284)
|
||||
- layout: null layout mode were items are not rendered but user can query GetItemRectMin()/Max/Size.
|
||||
- layout: (R&D) local multi-pass layout mode.
|
||||
- layout: (R&D) bind authored layout data (created by an off-line tool), items fetch their pos/size at submission, self-optimize data structures to stable linear access.
|
||||
|
||||
- tables: see https://github.com/ocornut/imgui/issues/2957#issuecomment-569726095
|
||||
|
||||
- group: BeginGroup() needs a border option. (~#1496)
|
||||
- group: IsItemHovered() after EndGroup() covers whole AABB rather than the intersection of individual items. Is that desirable?
|
||||
- group: merge deactivation/activation within same group (fwd WasEdited flag). (#2550)
|
||||
|
||||
!- color: the color conversion helpers/types are a mess and needs sorting out.
|
||||
- color: (api breaking) ImGui::ColorConvertXXX functions should be loose ImColorConvertXX to match imgui_internals.h
|
||||
|
||||
- plot: full featured plot/graph api w/ scrolling, zooming etc. --> ImPlot
|
||||
- (plot: deleted all other todo lines on 2023-06-28)
|
||||
|
||||
- clipper: ability to disable the clipping through a simple flag/bool.
|
||||
- clipper: ability to run without knowing full count in advance.
|
||||
- clipper: horizontal clipping support. (#2580)
|
||||
|
||||
- separator: expose flags (#759)
|
||||
- separator: take indent into consideration (optional)
|
||||
- separator: width, thickness, centering (#1643)
|
||||
- splitter: formalize the splitter idiom into an official api (we want to handle n-way split) (#319)
|
||||
|
||||
- docking: merge docking branch (#2109)
|
||||
|
||||
- tabs: "there is currently a problem because TabItem() will try to submit their own tooltip after 0.50 second, and this will have the effect of making your tooltip flicker once." -> tooltip priority work (WIP branch)
|
||||
- tabs: make EndTabBar fail if users doesn't respect BeginTabBar return value, for consistency/future-proofing.
|
||||
- tabs: persistent order/focus in BeginTabBar() api (#261, #351)
|
||||
- tabs: explicit api (even if internal) to cleanly manipulate tab order.
|
||||
|
||||
- image/image button: misalignment on padded/bordered button?
|
||||
- image/image button: parameters are confusing, image() has tint_col,border_col whereas imagebutton() has bg_col/tint_col. Even thou they are different parameters ordering could be more consistent. can we fix that?
|
||||
- slider: allow using the [-]/[+] buttons used by InputFloat()/InputInt()
|
||||
- slider: add dragging-based widgets to edit values with mouse (on 2 axises), saving screen real-estate.
|
||||
- slider: tint background based on value (e.g. v_min -> v_max, or use 0.0f either side of the sign)
|
||||
- slider: relative dragging? + precision dragging
|
||||
- slider: step option (#1183)
|
||||
- slider: style: fill % of the bar instead of positioning a drag.
|
||||
- knob: rotating knob widget (#942)
|
||||
- drag float: support for reversed drags (min > max) (removed is_locked, also see fdc526e)
|
||||
- drag float: up/down axis
|
||||
- drag float: power != 0.0f with current value being outside the range keeps the value stuck.
|
||||
- drag float: added leeway on edge (e.g. a few invisible steps past the clamp limits)
|
||||
|
||||
- combo: use clipper.
|
||||
- combo: a way/helper to customize the combo preview (#1658) -> experimental BeginComboPreview()
|
||||
- combo/listbox: keyboard control. need InputText-like non-active focus + key handling. considering keyboard for custom listbox (pr #203)
|
||||
- listbox: multiple selection (WIP range-select branch)
|
||||
- listbox: unselect option (#1208)
|
||||
- listbox: make it easier/more natural to implement range-select (need some sort of info/ref about the last clicked/focused item that user can translate to an index?) (WIP range-select branch)
|
||||
- listbox: user may want to initial scroll to focus on the one selected value?
|
||||
- listbox: disable capturing mouse wheel if the listbox has no scrolling. (#1681)
|
||||
- listbox: scrolling should track modified selection.
|
||||
- listbox: future api should allow to enable horizontal scrolling (#2510)
|
||||
|
||||
!- popups/menus: clarify usage of popups id, how MenuItem/Selectable closing parent popups affects the ID, etc. this is quite fishy needs improvement! (#331, #402)
|
||||
- modals: make modal title bar blink when trying to click outside the modal
|
||||
- modals: technically speaking, we could make Begin() with ImGuiWindowFlags_Modal work without involving popup. May help untangle a few things, as modals are more like regular windows than popups.
|
||||
- popups: if the popup functions took explicit ImGuiID it would allow the user to manage the scope of those ID. (#331)
|
||||
- popups: clicking outside (to close popup) and holding shouldn't drag window below.
|
||||
- popups: add variant using global identifier similar to Begin/End (#402)
|
||||
- popups: border options. richer api like BeginChild() perhaps? (#197)
|
||||
- popups/modals: although it is sometimes convenient that popups/modals lifetime is owned by imgui, we could also a bool-owned-by-user api as long as Begin() return value testing is enforced.
|
||||
|
||||
- tooltip: drag and drop with tooltip near monitor edges lose/changes its last direction instead of locking one. The drag and drop tooltip should always follow without changing direction.
|
||||
- tooltip: allow to set the width of a tooltip to allow TextWrapped() etc. while keeping the height automatic.
|
||||
- tooltip: drag tooltip hovering over source widget with IsItemHovered/SetTooltip flickers (WIP branch)
|
||||
|
||||
- status-bar: add a per-window status bar helper similar to what menu-bar does. generalize concept of layer0 rect in window (can make _MenuBar window flag obsolete too).
|
||||
- shortcuts: local-style shortcut api, e.g. parse "&Save"
|
||||
- shortcuts,menus: global-style shortcut api e.g. "Save (CTRL+S)" -> explicit flag for recursing into closed menu
|
||||
- shortcuts: programmatically access shortcuts "Focus("&Save"))
|
||||
- menus: menu-bar: main menu-bar could affect clamping of windows position (~ akin to modifying DisplayMin)
|
||||
- menus: hovering from menu to menu on a menu-bar has 1 frame without any menu, which is a little annoying. ideally either 0 either longer.
|
||||
- menus: would be nice if the Selectable() supported horizontal alignment (must be given the equivalent of WorkRect.Max.x matching the position of the shortcut column)
|
||||
|
||||
- tree node: add treenode/treepush int variants? not there because (void*) cast from int warns on some platforms/settings?
|
||||
- tree node: try to apply scrolling at time of TreePop() if node was just opened and end of node is past scrolling limits?
|
||||
- tree node / selectable render mismatch which is visible if you use them both next to each other (e.g. cf. property viewer)
|
||||
- tree node: tweak color scheme to distinguish headers from selected tree node (#581)
|
||||
- tree node: leaf/non-leaf highlight mismatch.
|
||||
- tree node: flag to disable formatting and/or detect "%s"
|
||||
- tree node/opt: could avoid formatting when clipped (flag assuming we don't care about width/height, assume single line height? format only %s/%c to be able to count height?)
|
||||
|
||||
- settings: write more decent code to allow saving/loading new fields: columns, selected tree nodes?
|
||||
- settings: api for per-tool simple persistent data (bool,int,float,columns sizes,etc.) in .ini file (#437)
|
||||
- settings/persistence: helpers to make TreeNodeBehavior persist (even during dev!) - may need to store some semantic and/or data type in ImGuiStoragePair
|
||||
|
||||
- style: better default styles. (#707)
|
||||
- style: PushStyleVar: allow direct access to individual float X/Y elements.
|
||||
- style: add a highlighted text color (for headers, etc.)
|
||||
- style: border types: out-screen, in-screen, etc. (#447)
|
||||
- style: add window shadow (fading away from the window. Paint-style calculation of vertices alpha after drawlist would be easier)
|
||||
- style: a concept of "compact style" that the end-user can easily rely on (e.g. PushStyleCompact()?) that maps to other settings? avoid implementing duplicate helpers such as SmallCheckbox(), etc.
|
||||
- style: try to make PushStyleVar() more robust to incorrect parameters (to be more friendly to edit & continues situation).
|
||||
- style: global scale setting.
|
||||
- style: FramePadding could be different for up vs down (#584)
|
||||
- style: WindowPadding needs to be EVEN as the 0.5 multiplier used on this value probably have a subtle effect on clip rectangle
|
||||
- style: have a more global HSV setter (e.g. alter hue on all elements). consider replacing active/hovered by offset in HSV space? (#438, #707, #1223)
|
||||
- style: gradients fill (#1223) ~ 2 bg colors for each fill? tricky with rounded shapes and using textures for corners.
|
||||
- style editor: color child window height expressed in multiple of line height.
|
||||
|
||||
- log: improve logging of ArrowButton, ListBox, TabItem
|
||||
- log: carry on indent / tree depth when opening a child window
|
||||
- log: enabling log ends up pushing and growing vertices buffers because we don't distinguish layout vs render clipping
|
||||
- log: have more control over the log scope (e.g. stop logging when leaving current tree node scope)
|
||||
- log: be able to log anything (e.g. right-click on a window/tree-node, shows context menu? log into tty/file/clipboard)
|
||||
- log: let user copy any window content to clipboard easily (CTRL+C on windows? while moving it? context menu?). code is commented because it fails with multiple Begin/End pairs.
|
||||
- log: obsolete LogButtons().... (was: LogButtons() options for specifying depth and/or hiding depth slider)
|
||||
|
||||
- filters: set a current filter that certains items (e.g. tree node) can automatically query to hide themselves
|
||||
- filters: handle wild-cards (with implicit leading/trailing *), reg-exprs
|
||||
- filters: fuzzy matches (may use code at blog.forrestthewoods.com/4cffeed33fdb)
|
||||
|
||||
- drag and drop: focus drag target window on hold (even without open)
|
||||
- drag and drop: releasing a drop shows the "..." tooltip for one frame - since e13e598 (#1725)
|
||||
- drag and drop: drag source on a group object (would need e.g. an invisible button covering group in EndGroup) https://twitter.com/paniq/status/1121446364909535233
|
||||
- drag and drop: have some way to know when a drag begin from BeginDragDropSource() pov. (see 2018/01/11 post in #143)
|
||||
- drag and drop: allow preview tooltip to be submitted from a different place than the drag source. (#1725)
|
||||
- drag and drop: make it easier and provide a demo to have tooltip both are source and target site, with a more detailed one on target site (tooltip ordering problem)
|
||||
- drag and drop: demo with reordering nodes (in a list, or a tree node). (#143)
|
||||
- drag and drop: test integrating with os drag and drop (make it easy to do a naive WM_DROPFILE integration)
|
||||
- drag and drop: allow for multiple payload types. (#143)
|
||||
- drag and drop: make payload optional? payload promise? (see 2018/01/11 post in #143)
|
||||
- drag and drop: (#143) "both an in-process pointer and a promise to generate a serialized version, for whether the drag ends inside or outside the same process"
|
||||
- drag and drop: feedback when hovering a region blocked by modal (mouse cursor "NO"?)
|
||||
|
||||
- markup: simple markup language for color change? (#902, #3130)
|
||||
|
||||
- text: selectable text (for copy) as a generic feature (ItemFlags?)
|
||||
- text: proper alignment options in imgui_internal.h
|
||||
- text: provided a framed text helper, e.g. https://pastebin.com/1Laxy8bT
|
||||
- text: refactor TextUnformatted (or underlying function) to more explicitly request if we need width measurement or not
|
||||
- text/layout/tabs: \t pulling position from base pos + step, or offset array (e.g. could be used in text edit, menus for simple icon+text alignment, etc.)
|
||||
- text link/url button: underlined. should api expose an ID or use text contents as ID? which colors enum to use?
|
||||
- text/wrapped: should be a more first-class citizen, e.g. wrapped text within a Selectable with known width.
|
||||
- text/wrapped: custom separator for text wrapping. (#3002)
|
||||
- text/wrapped: figure out better way to use TextWrapped() in an always auto-resize context (tooltip, etc.) (#249)
|
||||
|
||||
- font: arbitrary line spacing. (#2945)
|
||||
- font: MergeMode: flags to select overwriting or not (this is now very easy with refactored ImFontAtlasBuildWithStbTruetype)
|
||||
- font: free the Alpha buffer if user only requested RGBA.
|
||||
!- font: better CalcTextSizeA() API, at least for simple use cases. current one is horrible (perhaps have simple vs extended versions).
|
||||
- font: for the purpose of RenderTextEllipsis(), it might be useful that CalcTextSizeA() can ignore the trailing padding?
|
||||
- font: a CalcTextHeight() helper could run faster than CalcTextSize().y
|
||||
- font: enforce monospace through ImFontConfig (for icons?) + create dual ImFont output from same input, reusing rasterized data but with different glyphs/AdvanceX
|
||||
- font: finish CustomRectRegister() to allow mapping Unicode codepoint to custom texture data
|
||||
- font: remove ID from CustomRect registration, it seems unnecessary!
|
||||
- font: make it easier to submit own bitmap font (same texture, another texture?). (#2127, #2575)
|
||||
- font: PushFontSize API (#1018)
|
||||
- font: MemoryTTF taking ownership confusing/not obvious, maybe default should be opposite?
|
||||
- font: storing MinAdvanceX per font would allow us to skip calculating line width (under a threshold of character count) in loops looking for block width
|
||||
- font/demo: add tools to show glyphs used by a text blob, display U16 value, list missing glyphs.
|
||||
- font/demo: demonstrate use of ImFontGlyphRangesBuilder.
|
||||
- font/atlas: add a missing Glyphs.reserve()
|
||||
- font/atlas: incremental updates
|
||||
- font/atlas: dynamic font atlas to avoid baking huge ranges into bitmap and make scaling easier.
|
||||
- font/draw: vertical and/or rotated text renderer (#705) - vertical is easier clipping wise
|
||||
- font/draw: need to be able to specify wrap start position.
|
||||
- font/draw: better reserve policy for large horizontal block of text (shouldn't reserve for all clipped lines). also see #3349.
|
||||
- font/draw: fix for drawing 16k+ visible characters in same call.
|
||||
- font/draw: underline, squiggle line rendering helpers.
|
||||
- font: optimization: for monospace font (like the default one) we can trim IndexXAdvance as long as trailing value is == FallbackXAdvance (need to make sure TAB is still correct), would save on cache line.
|
||||
- font: add support for kerning, probably optional. A) perhaps default to (32..128)^2 matrix ~ 9K entries = 36KB, then hash for non-ascii?. B) or sparse lookup into per-char list?
|
||||
- font: add a simpler CalcTextSizeA() api? current one ok but not welcome if user needs to call it directly (without going through ImGui::CalcTextSize)
|
||||
- font: fix AddRemapChar() to work before atlas has been built.
|
||||
- font: (api breaking) remove "TTF" from symbol names. also because it now supports OTF.
|
||||
- font/opt: Considering storing standalone AdvanceX table as 16-bit fixed point integer?
|
||||
- font/opt: Glyph currently 40 bytes (2+9*4). Consider storing UV as 16-bits integer? (->32 bytes). X0/Y0/X1/Y1 as 16 fixed-point integers? Or X0/Y0 as float and X1/Y1 as fixed8_8?
|
||||
|
||||
- nav: visual feedback on button press.
|
||||
- nav: some features such as PageUp/Down/Home/End should probably work without ImGuiConfigFlags_NavEnableKeyboard? (where do we draw the line? how about CTRL+Tab)
|
||||
! nav: never clear NavId on some setup (e.g. gamepad centric)
|
||||
- nav: there's currently no way to completely clear focus with the keyboard. depending on patterns used by the application to dispatch inputs, it may be desirable.
|
||||
- nav: Home/End behavior when navigable item is not fully visible at the edge of scrolling? should be backtrack to keep item into view?
|
||||
- nav: NavScrollToBringItemIntoView() with item bigger than view should focus top-right? Repro: using Nav in "About Window"
|
||||
- nav: wrap around logic to allow e.g. grid based layout (pressing NavRight on the right-most element would go to the next row, etc.). see internal's NavMoveRequestTryWrapping().
|
||||
- nav: patterns to make it possible for arrows key to update selection (see JustMovedTo in range_select branch)
|
||||
- nav: restore/find nearest NavId when current one disappear (e.g. pressed a button that disappear, or perhaps auto restoring when current button change name)
|
||||
- nav: SetItemDefaultFocus() level of priority, so widget like Selectable when inside a popup could claim a low-priority default focus on the first selected iem
|
||||
- nav: NavFlattened: init requests don't work properly on flattened siblings.
|
||||
- nav: NavFlattened: pageup/pagedown/home/end don't work properly on flattened siblings.
|
||||
- nav: NavFlattened: ESC on a flattened child should select something.
|
||||
- nav: NavFlattened: broken: in typical usage scenario, the items of a fully clipped child are currently not considered to enter into a NavFlattened child.
|
||||
- nav: NavFlattened: cannot access menu-bar of a flattened child window with Alt/menu key (not a very common use case..).
|
||||
- nav: simulate right-click or context activation? (SHIFT+F10, keyboard Menu key?)
|
||||
- nav/popup: esc/enter default behavior for popups, e.g. be able to mark an "ok" or "cancel" button that would get triggered by those keys, default validation button, etc.
|
||||
- nav/treenode: left within a tree node block as a fallback (ImGuiTreeNodeFlags_NavLeftJumpsBackHere by default?)
|
||||
- nav/menus: pressing left-right on a vertically clipped menu bar tends to jump to the collapse/close buttons.
|
||||
- nav/menus: allow pressing Menu to leave a sub-menu.
|
||||
- nav/menus: a way to access the main menu bar with Alt? (currently needs CTRL+TAB) or last focused window menu bar?
|
||||
- nav/menus: when using the main menu bar, even though we restore focus after, the underlying window loses its title bar highlight during menu manipulation. could we prevent it?
|
||||
- nav/menus: main menu bar currently cannot restore a nullptr focus. Could save NavWindow at the time of being focused, similarly to what popup do?
|
||||
- nav/menus: Alt,Up could open the first menu (e.g. "File") currently it tends to nav into the window/collapse menu. Do do that we would need custom transition?
|
||||
- nav/windowing: when CTRL+Tab/windowing is active, the HoveredWindow detection doesn't take account of the window display re-ordering.
|
||||
- nav/windowing: Resizing window will currently fail with certain types of resizing constraints/callback applied
|
||||
- focus: preserve ActiveId/focus stack state, e.g. when opening a menu and close it, previously selected InputText() focus gets restored (#622)
|
||||
|
||||
- inputs: support track pad style scrolling & slider edit.
|
||||
- inputs/io: backspace and arrows in the context of a text input could use system repeat rate.
|
||||
- inputs/io: clarify/standardize/expose repeat rate and repeat delays (#1808)
|
||||
- inputs/scrolling: support for smooth scrolling (#2462, #2569)
|
||||
|
||||
- misc: idle: expose "woken up" boolean (set by inputs) and/or animation time (for cursor blink) for backend to be able stop refreshing easily.
|
||||
- misc: idle: if cursor blink if the _only_ visible animation, core imgui could rewrite vertex alpha to avoid CPU pass on ImGui:: calls.
|
||||
- misc: idle: if cursor blink if the _only_ visible animation, could even expose a dirty rectangle that optionally can be leverage by some app to render in a smaller viewport, getting rid of much pixel shading cost.
|
||||
- misc: no way to run a root-most GetID() with ImGui:: api since there's always a Debug window in the stack. (mentioned in #2960)
|
||||
- misc: make the ImGuiCond values linear (non-power-of-two). internal storage for ImGuiWindow can use integers to combine into flags (Why?)
|
||||
- misc: PushItemFlag(): add a flag to disable keyboard capture when used with mouse? (#1682)
|
||||
- misc: use more size_t in public api?
|
||||
- misc: possible compile-time support for string view/range instead of char* would e.g. facilitate usage with Rust (#683, #3038, WIP string_view branch)
|
||||
- misc: possible compile-time support for wchar_t instead of char*?
|
||||
|
||||
- demo: demonstrate using PushStyleVar() in more details.
|
||||
- demo: add vertical separator demo
|
||||
- demo: add virtual scrolling example?
|
||||
- demo: demonstrate Plot offset
|
||||
- demo: window size constraint: square demo is broken when resizing from edges (#1975), would need to rework the callback system to solve this
|
||||
|
||||
- examples: window minimize, maximize (#583)
|
||||
- examples: provide a zero frame-rate/idle example.
|
||||
- examples: dx11/dx12: try to use new swapchain blit models (#2970)
|
||||
- backends: report it better when not able to create texture?
|
||||
- backends: glfw: could go idle when minimized? if (glfwGetWindowAttrib(window, GLFW_ICONIFIED)) { glfwWaitEvents(); continue; } // issue: DeltaTime will be super high on resume, perhaps provide a way to let impl know (#440)

- backends: opengl: rename imgui_impl_opengl2 to impl_opengl_legacy and imgui_impl_opengl3 to imgui_impl_opengl? (#1900)
|
||||
- backends: opengl: could use a single vertex buffer and glBufferSubData for uploads?
|
||||
- backends: opengl: explicitly disable GL_STENCIL_TEST in bindings.
|
||||
- backends: vulkan: viewport: support for synchronized swapping of multiple swap chains.
|
||||
- backends: bgfx: https://gist.github.com/RichardGale/6e2b74bc42b3005e08397236e4be0fd0
|
||||
- backends: emscriptem: with refactored examples, we could provide a direct imgui_impl_emscripten platform layer (see eg. https://github.com/floooh/sokol-samples/blob/master/html5/imgui-emsc.cc#L42)
|
||||
|
||||
- bindings: ways to use clang ast dump to generate bindings or helpers for bindings? (e.g. clang++ -Xclang -ast-dump=json imgui.h) (WIP project "dear-bindings" still private)
|
||||
|
||||
- optimization: replace vsnprintf with stb_printf? using IMGUI_USE_STB_SPRINTF. (#1038 + needed for string_view)
|
||||
- optimization: add clipping for multi-component widgets (SliderFloatX, ColorEditX, etc.). one problem is that nav branch can't easily clip parent group when there is a move request.
|
||||
- optimization: add a flag to disable most of rendering, for the case where the user expect to skip it (#335)
|
||||
- optimization: fully covered window (covered by another with non-translucent bg + WindowRounding worth of padding) may want to clip rendering.
|
||||
- optimization: use another hash function than crc32, e.g. FNV1a
|
||||
- optimization: turn some the various stack vectors into statically-sized arrays

# Configuration
|
||||
|
||||
Dear ImGui outputs 16-bit vertex indices by default.
|
||||
Allegro doesn't support them natively, so we have two solutions: convert the indices manually in imgui_impl_allegro5.cpp, or compile dear imgui with 32-bit indices.
|
||||
You can either modify imconfig.h that comes with Dear ImGui (easier), or set a C++ preprocessor option IMGUI_USER_CONFIG to find to a filename.
|
||||
We are providing `imconfig_allegro5.h` that enables 32-bit indices.
|
||||
Note that the backend supports _BOTH_ 16-bit and 32-bit indices, but 32-bit indices will be slightly faster as they won't require a manual conversion.
|
||||

# How to Build
|
||||
|
||||
### On Ubuntu 14.04+ and macOS
|
||||
|
||||
```bash
|
||||
g++ -DIMGUI_USER_CONFIG=\"examples/example_allegro5/imconfig_allegro5.h\" -I .. -I ../.. -I ../../backends main.cpp ../../backends/imgui_impl_allegro5.cpp ../../imgui*.cpp -lallegro -lallegro_main -lallegro_primitives -o allegro5_example
|
||||
```
|
||||
|
||||
On macOS, install Allegro with homebrew: `brew install allegro`.
|
||||
|
||||
### On Windows with Visual Studio's CLI
|
||||
|
||||
You may install Allegro using vcpkg:
|
||||
```
|
||||
git clone https://github.com/Microsoft/vcpkg
|
||||
cd vcpkg
|
||||
bootstrap-vcpkg.bat
|
||||
vcpkg install allegro5 --triplet=x86-windows ; for win32
|
||||
vcpkg install allegro5 --triplet=x64-windows ; for win64
|
||||
vcpkg integrate install ; register include / libs in Visual Studio
|
||||
```
|
||||
|
||||
Build:
|
||||
```
|
||||
set ALLEGRODIR=path_to_your_allegro5_folder
|
||||
cl /Zi /MD /utf-8 /I %ALLEGRODIR%\include /DIMGUI_USER_CONFIG=\"examples/example_allegro5/imconfig_allegro5.h\" /I .. /I ..\.. /I ..\..\backends main.cpp ..\..\backends\imgui_impl_allegro5.cpp ..\..\imgui*.cpp /link /LIBPATH:%ALLEGRODIR%\lib allegro-5.0.10-monolith-md.lib user32.lib

# iOS / OSX Metal example
|
||||
|
||||
## Introduction
|
||||
|
||||
This example shows how to integrate Dear ImGui with Metal. It is based on the "cross-platform" game template provided with Xcode as of Xcode 9.
|
||||
|
||||
Consider basing your work off the example_glfw_metal/ or example_sdl2_metal/ examples. They are better supported and will be portable unlike this one.

## How to Build
|
||||
|
||||
- You need to install Emscripten from https://emscripten.org/docs/getting_started/downloads.html, and have the environment variables set, as described in https://emscripten.org/docs/getting_started/downloads.html#installation-instructions
|
||||
|
||||
- Depending on your configuration, in Windows you may need to run `emsdk/emsdk_env.bat` in your console to access the Emscripten command-line tools.
|
||||
|
||||
- You may also refer to our [Continuous Integration setup](https://github.com/ocornut/imgui/tree/master/.github/workflows) for Emscripten setup.
|
||||
|
||||
- Then build using `make` while in the `example_emscripten_wgpu/` directory.
|
||||
|
||||
- Requires recent Emscripten as WGPU is still a work-in-progress API.
|
||||
|
||||
## How to Run
|
||||
|
||||
To run on a local machine:
|
||||
- Make sure your browse supports WGPU and it is enabled. WGPU is still WIP not enabled by default in most browser.
|
||||
- `make serve` will use Python3 to spawn a local webserver, you can then browse http://localhost:8000 to access your build.
|
||||
- Otherwise, generally you will need a local webserver:
|
||||
- Quoting [https://emscripten.org/docs/getting_started](https://emscripten.org/docs/getting_started/Tutorial.html#generating-html):<br>
|
||||
_"Unfortunately several browsers (including Chrome, Safari, and Internet Explorer) do not support file:// [XHR](https://emscripten.org/docs/site/glossary.html#term-xhr) requests, and can’t load extra files needed by the HTML (like a .wasm file, or packaged file data as mentioned lower down). For these browsers you’ll need to serve the files using a [local webserver](https://emscripten.org/docs/getting_started/FAQ.html#faq-local-webserver) and then open http://localhost:8000/hello.html."_
|
||||
- Emscripten SDK has a handy `emrun` command: `emrun web/example_emscripten_opengl3.html --browser firefox` which will spawn a temporary local webserver (in Firefox). See https://emscripten.org/docs/compiling/Running-html-files-with-emrun.html for details.
|
||||
- You may use Python 3 builtin webserver: `python -m http.server -d web` (this is what `make serve` uses).
|
||||
- You may use Python 2 builtin webserver: `cd web && python -m SimpleHTTPServer`.
|
||||
- If you are accessing the files over a network, certain browsers, such as Firefox, will restrict Gamepad API access to secure contexts only (e.g. https only).
