Narrowing your problem to its shortest and purest form is the easiest way to understand it, explain it and fix it. Please test your shortened code to ensure it exhibits the problem. Often while creating the MCVE you will solve 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."

// 2023-12-19: Emscripten: Added ImGui_ImplGlfw_InstallEmscriptenCanvasResizeCallback() to register canvas selector and auto-resize GLFW window.
// 2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys.
// 2023-07-18: Inputs: Revert ignoring mouse data on GLFW_CURSOR_DISABLED as it can be used differently. User may set ImGuiConfigFLags_NoMouse if desired. (#5625, #6609)
// 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)

// (minor and older changes stripped away, please see git history for details)
// 2024-04-15: Inputs: Re-enable calling SDL_StartTextInput()/SDL_StopTextInput() as SDL3 no longer enables it by default and should play nicer with IME.
// 2024-02-13: Inputs: Fixed gamepad support. Handle gamepad disconnection. Added ImGui_ImplSDL3_SetGamepadMode().
// 2023-11-13: Updated for recent SDL3 API changes.
// 2023-10-05: Inputs: Added support for extra ImGuiKey values: F13 to F24 function keys, app back/forward keys.
// 2023-05-04: Fixed build on Emscripten/iOS/Android. (#6391)
// 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)

// CHANGELOG
// (minor and older changes stripped away, please see git history for details)
// 2024-04-19: Vulkan: Added convenience support for Volk via IMGUI_IMPL_VULKAN_USE_VOLK define (you can also use IMGUI_IMPL_VULKAN_NO_PROTOTYPES + wrap Volk via ImGui_ImplVulkan_LoadFunctions().)
// 2024-02-14: *BREAKING CHANGE*: Moved RenderPass parameter from ImGui_ImplVulkan_Init() function to ImGui_ImplVulkan_InitInfo structure. Not required when using dynamic rendering.
// 2024-02-12: *BREAKING CHANGE*: Dynamic rendering now require filling PipelineRenderingCreateInfo structure.
// 2024-01-19: Vulkan: Fixed vkAcquireNextImageKHR() validation errors in VulkanSDK 1.3.275 by allocating one extra semaphore than in-flight frames. (#7236)
// 2024-01-11: Vulkan: Fixed vkMapMemory() calls unnecessarily using full buffer size (#3957). Fixed MinAllocationSize handing (#7189).
// 2024-01-03: Vulkan: Added MinAllocationSize field in ImGui_ImplVulkan_InitInfo to workaround zealous "best practice" validation layer. (#7189, #4238)
// 2024-01-03: Vulkan: Stopped creating command pools with VK_COMMAND_POOL_CREATE_RESET_COMMAND_BUFFER_BIT as we don't reset them.
// 2023-11-29: Vulkan: Fixed mismatching allocator passed to vkCreateCommandPool() vs vkDestroyCommandPool(). (#7075)
// 2023-11-10: *BREAKING CHANGE*: Removed parameter from ImGui_ImplVulkan_CreateFontsTexture(): backend now creates its own command-buffer to upload fonts.
// *BREAKING CHANGE*: Removed ImGui_ImplVulkan_DestroyFontUploadObjects() which is now unnecessary as we create and destroy those objects in the backend.
// ImGui_ImplVulkan_CreateFontsTexture() is automatically called by NewFrame() the first time.
// You can call ImGui_ImplVulkan_CreateFontsTexture() again to recreate the font atlas texture.
// Added ImGui_ImplVulkan_DestroyFontsTexture() but you probably never need to call this.
// 2023-07-04: Vulkan: Added optional support for VK_KHR_dynamic_rendering. User needs to set init_info->UseDynamicRendering = true and init_info->ColorAttachmentFormat.
// 2023-01-02: Vulkan: Fixed sampler passed to ImGui_ImplVulkan_AddTexture() not being honored + removed a bunch of duplicate code.
// 2022-10-11: Using 'nullptr' instead of 'NULL' as per our switch to C++11.
// 2022-10-04: Vulkan: Added experimental ImGui_ImplVulkan_RemoveTexture() for api symmetry. (#914, #5738).
// 2022-10-04: Vulkan: Added experimental ImGui_ImplVulkan_RemoveTexture() for api symetry. (#914, #5738).
// 2022-01-20: Vulkan: Added support for ImTextureID as VkDescriptorSet. User need to call ImGui_ImplVulkan_AddTexture(). Building for 32-bit targets requires '#define ImTextureID ImU64'. (#914).
// 2021-10-15: Vulkan: Call vkCmdSetScissor() at the end of render a full-viewport to reduce likehood of issues with people using VK_DYNAMIC_STATE_SCISSOR in their app without calling vkCmdSetScissor() explicitly every frame.
// 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).

// 2024-01-22: Added configurable PipelineMultisampleState struct. (#7240)
// 2024-01-22: (Breaking) ImGui_ImplWGPU_Init() now takes a ImGui_ImplWGPU_InitInfo structure instead of variety of parameters, allowing for easier further changes.
// 2024-01-22: Fixed pipeline layout leak. (#7245)
// 2024-01-17: Explicitly fill all of WGPUDepthStencilState since standard removed defaults.
// 2023-07-13: Use WGPUShaderModuleWGSLDescriptor's code instead of source. use WGPUMipmapFilterMode_Linear instead of WGPUFilterMode_Linear. (#6602)
// 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).

WHEN TO UPDATE?
- Keeping your copy of Dear ImGui updated regularly is recommended.
- It is generally safe and recommended to sync to the latest commit in 'master' or 'docking'
branches. The library is fairly stable and regressions tends to be fixed fast when reported.
- It is generally safe to sync to the latest commit in master or docking branches
The library is fairly stable and regressions tends to be fixed fast when reported.
HOW TO UPDATE?
- Update submodule or copy/overwrite every file.
- About imconfig.h:
- You may modify your copy of imconfig.h, in this case don't overwrite it.
- or you may locally branch to modify imconfig.h and merge/rebase latest.
- or you may '#define IMGUI_USER_CONFIG "my_config_file.h"' globally from your build system to
specify a custom path for your imconfig.h file and instead not have to modify the default one.
- Overwrite every file except imconfig.h (if you have modified it).
- You may also locally branch to modify imconfig.h and merge latest into your branch.
- Read the `Breaking Changes` section (in imgui.cpp or here in the Changelog).
- If you have a problem with a missing function/symbols, search for its name in the code, there will likely be a comment about it.
- If you are copying this repository in your codebase, please leave the demo and documentations files in there, they will be useful.
- If you are dropping this repository in your codebase, please leave the demo and text files in there, they will be useful.
- You may diff your previous Changelog with the one you just copied and read that diff.
- You may enable `IMGUI_DISABLE_OBSOLETE_FUNCTIONS` in imconfig.h to forcefully disable legacy names and symbols.
Doing it every once in a while is a good way to make sure you are not using obsolete symbols. Dear ImGui is in active development,
and API updates have been a little more frequent lately. They are documented below and in imgui.cpp and should not affect all users.
- Please report any issue!

VERSION 1.90.7 (Released 2024-05-27)
-----------------------------------------------------------------------
Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.7
Breaking changes:
- Inputs: on macOS X, Cmd and Ctrl keys are now automatically swapped by io.AddKeyEvent(),
as this naturally align with how macOS X uses those keys. (#2343, #4084, #5923, #456)
- Effectively it means that e.g. ImGuiMod_Ctrl | ImGuiKey_C is a valid idiomatic shortcut
for both Windows and Mac style users.
- It shouldn't really affect your code unless you had explicit/custom shortcut swapping in
place for macOS X apps in your input logic.
- Removed ImGuiMod_Shortcut which was previously dynamically remapping to Ctrl or Cmd/Super.
It is now unnecessary to specific cross-platform idiomatic shortcuts.
Kept symbols redirecting ImGuiMod_Shortcut to ImGuiMod_Ctrl (will obsolete).
- Commented out obsolete symbols renamed in 1.88 (May 2022):
CaptureKeyboardFromApp() -> SetNextFrameWantCaptureKeyboard()
CaptureMouseFromApp() -> SetNextFrameWantCaptureMouse()
- Backends: SDL_Renderer2/SDL_Renderer3: ImGui_ImplSDLRenderer2_RenderDrawData() and
ImGui_ImplSDLRenderer3_RenderDrawData() now takes a SDL_Renderer* parameter. This was previously
overlooked from the API but it will allow eventual support for multi-viewports.
Other changes:
- Windows: BeginChild(): fixed visibility of fully clipped child windows and tables to Test Engine.
- Windows: BeginChild(): fixed auto-fit calculation when using either (not both) ResizeX/ResizeY
and double-clicking on a border. Calculation incorrectly didn't always account for scrollbar as
it assumed the other axis would also be auto-fit. (#1710)
- Inputs: added shortcut and routing system in public API. (#456, #2637) [BETA]
- The general idea is that several callers may register interest in a shortcut, and only one owner gets it.
- in Parent: call Shortcut(Ctrl+S) // When Parent is focused, Parent gets the shortcut.
- in Child1: call Shortcut(Ctrl+S) // When Child1 is focused, Child1 gets the shortcut (Child1 overrides Parent shortcuts)
- in Child2: no call // When Child2 is focused, Parent gets the shortcut.
The whole system is order independent, so if Child1 makes its calls before Parent, results will be identical.
This is an important property as it facilitate working with foreign code or larger codebase.
- Added Shortcut() function:
e.g. Using ImGui::Shortcut(ImGuiMod_Ctrl | ImGuiKey_C); with default policy:
- checks that CTRL+C is pressed,
- and that current window is in focus stack,
- and that no other requests for CTRL+C have been made from higher priority locations
(e.g. deeper in the window/item stack).
- Added SetNextItemShortcut() to set a shortcut to locally or remotely press or activate
an item (depending on specified routing policy: using ImGuiInputFlags_RouteGlobal the item
shortcut may be executed even if its window is not in focus stack).
Items like buttons are not fully activated, in the sense that they get pressed but another
active item, e.g. InputText() won't be deactivated.
- Added routing policies for Shortcut(), SetNextItemShortcut(): (#456, #2637)
- ImGuiInputFlags_RouteFocused: focus stack route (default)
- ImGuiInputFlags_RouteActive: only route to active item
- ImGuiInputFlags_RouteGlobal: route globally, unless a focus route claim shame shortcut.
- ImGuiInputFlags_RouteAlways: no routing submission, no routing check.
- Added other shortcut/routing options: (#456, #2637)
- ImGuiInputFlags_Repeat: for use by Shortcut() and by upcoming rework of various
input functions (which are still internal for now).
- ImGuiInputFlags_Tooltip: for SetNextItemShortcut() to show a tooltip when hovering item.
- ImGuiInputFlags_RouteOverFocused: global route takes priority over focus route.
- ImGuiInputFlags_RouteOverActive: global route takes priority over active item.
- ImGuiInputFlags_RouteUnlessBgFocused: global route disabled if no imgui window focused.
- ImGuiInputFlags_RouteFromRootWindow: route evaluated from the point of view of root window rather than current window.
- Inputs: (OSX) Fixes variety of code which inconsistently required using Ctrl instead of Cmd.
- e.g. Drags/Sliders now use Cmd+Click to input a value. (#4084)
- Some shortcuts still uses Ctrl on Mac: e.g. Ctrl+Tab to switch windows. (#4828)
- Inputs: (OSX) Ctrl+Left Click alias as a Right click. (#2343) [@haldean, @ocornut]
- Inputs: Fixed ImGui::GetKeyName(ImGuiKey_None) from returning "N/A" or "None" depending
on value of IMGUI_DISABLE_OBSOLETE_KEYIO. It always returns "None".
- Nav: fixed holding Ctrl or gamepad L1 from not slowing down keyboard/gamepad tweak speed.
Broken during a refactor refactor for 1.89. Holding Shift/R1 to speed up wasn't broken.
- Tables: fixed cell background of fully clipped row overlapping with header. (#7575, #7041) [@prabuinet]
- Demo: Added "Inputs & Focus -> Shortcuts" section. (#456, #2637)
- Demo: Documents: Added shortcuts and renaming tabs/documents. (#7233)
- Examples: Win32+DX9,DX10,DX11,DX12: rework main loop to handle minimization and screen
locking without burning resources by running unthrottled code. (#2496, #3907, #6308, #7615)
- Backends: all backends + demo now call IMGUI_CHECKVERSION() to verify ABI compatibility between caller
code and compiled version of Dear ImGui. If you get an assert it most likely mean you have a build issue,
read comments near the assert. (#7568)
- Backends: Win32: undo an assert introduced in 1.90.6 which didn't allow WndProc
handler to be called before backend initialization. Because of how ::CreateWindow()
calls in WndProc this is facilitating. (#6275) [@MennoVink]
- Backends, Examples: SDL3: updates for latest SDL3 API changes. (#7580) [@kuvaus, @ocornut]
Breaking changes IF you were using imgui_internal.h versions of Shortcut() or owner-aware
versions of IsKeyPressed(), IsKeyChordPressed(), IsMouseClicked() prior to this version:
- Inputs (Internals): Renamed ImGuiKeyOwner_None to ImGuiKeyOwner_NoOwner, to make use more
explicit and reduce confusion with the fact it is a non-zero value and cannot be a default.
- Inputs (Internals): Renamed symbols global routes:
Renamed ImGuiInputFlags_RouteGlobalLow -> ImGuiInputFlags_RouteGlobal (this is the suggested global route)
Renamed ImGuiInputFlags_RouteGlobal -> ImGuiInputFlags_RouteGlobal | ImGuiInputFlags_RouteOverFocused
Renamed ImGuiInputFlags_RouteGlobalHigh -> ImGuiInputFlags_RouteGlobal | ImGuiInputFlags_RouteOverFocused | ImGuiInputFlags_RouteOverActive
- Inputs (Internals): Shortcut(), SetShortcutRouting(): swapped last two parameters order
in function signatures:
Before: Shortcut(ImGuiKeyChord key_chord, ImGuiID owner_id = 0, ImGuiInputFlags flags = 0);
After: Shortcut(ImGuiKeyChord key_chord, ImGuiInputFlags flags = 0, ImGuiID owner_id = 0);
- Inputs (Internals): owner-aware versions of IsKeyPressed(), IsKeyChordPressed(), IsMouseClicked():
swapped last two parameters order in function signatures:
Before: IsKeyPressed(ImGuiKey key, ImGuiID owner_id, ImGuiInputFlags flags = 0);
After: IsKeyPressed(ImGuiKey key, ImGuiInputFlags flags, ImGuiID owner_id = 0);
Before: IsMouseClicked(ImGuiMouseButton button, ImGuiID owner_id, ImGuiInputFlags flags = 0);
After: IsMouseClicked(ImGuiMouseButton button, ImGuiInputFlags flags, ImGuiID owner_id = 0);
- For several reasons those changes makes sense. They were all made before making some of
those API public. Only past users of imgui_internal.h with the extra parameters will be affected.
Added asserts for valid flags in various functions to detect _some_ misuses, BUT NOT ALL.
-----------------------------------------------------------------------
VERSION 1.90.6 (Released 2024-05-08)
-----------------------------------------------------------------------
Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.6
Breaking changes:
- TreeNode: Fixed a layout inconsistency when using a empty/hidden label followed
by a SameLine() call. (#7505, #282)
Before: TreeNode("##Hidden"); SameLine(); Text("Hello");
// This was actually incorrect! BUT appeared to look ok with the default style
// where ItemSpacing.x == FramePadding.x * 2 (it didn't look aligned otherwise).
After: TreeNode("##Hidden"); SameLine(0, 0); Text("Hello");
// This is correct for all values in style.
With the fix, IF you were successfully using TreeNode("")+SameLine(); you will now
have extra spacing between your TreeNode and the following item. You'll need to change
the SameLine() call to SameLine(0,0) to remove this extraneous spacing.
This seemed like the more sensible fix that's not making things less consistent.
(Note: when using this idiom you are likely to also use ImGuiTreeNodeFlags_SpanAvailWidth).
Other changes:
- Windows: Changed default ClipRect to extend to windows' left and right borders,
instead of adding arbitrary WindowPadding.x * 0.5f space on left and right.
That ClipRect half-padding was arbitrary/confusing and inconsistent with Y axis.
It also made it harder to draw items covering whole window without pushing an
extended ClipRect. Some items near windows left and right edge that used to be clipped
may be partly more visible. (#3312, #7540, #3756, #6170, #6365)
- Windows: Fixed subsequent Begin() append calls from setting last item information
for title bar, making it impossible to use IsItemHovered() on a Begin()-to-append,
and causing issue bypassing hover detection on collapsed windows. (#7506, #823)
- Fonts: Fixed font ascent and descent calculation when a font hits exact integer values.
It is possible that some prior manual use of ImFontConfig::GlyphOffset may become
duplicate with this fix. (#7399, #7404) [@GamingMinds-DanielC]
- TreeNode: Added ImGuiTreeNodeFlags_SpanTextWidth to make hitbox and highlight only
cover the label. (#6937) [@dimateos]
- Tables: Angled headers: fixed multi-line label display when angle is flipped. (#6917)
- Tables: Angled headers: added style.TableAngledHeadersTextAlign and corresponding
ImGuiStyleVar_TableAngledHeadersTextAlign variable. Default to horizontal center. (#6917)
[@thedmd, @ocornut]
- ProgressBar: Added support for indeterminate progress bar by passing an animated
negative fraction, e.g. ProgressBar(-1.0f * GetTime()). (#5316, #5370, #1901)[@gan74]
- Text, DrawList: Improved handling of long single-line wrapped text. Faster and
mitigate issues with reading vertex indexing limits with 16-bit indices. (#7496, #5720)
- Backends: OpenGL3: Detect ES3 contexts on desktop based on version string,
to e.g. avoid calling glPolygonMode() on them. (#7447) [@afraidofdark, @ocornut]
- Backends: OpenGL3: Update loader for Linux to support EGL/GLVND. (#7562) [@ShadowNinja, @vanfanel]
- Backends: Vulkan: Added convenience support for Volk via IMGUI_IMPL_VULKAN_USE_VOLK define.
(you could always use IMGUI_IMPL_VULKAN_NO_PROTOTYPES + ImGui_ImplVulkan_LoadFunctions() as well).
(#6582, #4854) [@adalsteinnh, @kennyalive, @ocornut]
- Backends: SDL3: Fixed text inputs. Re-enable calling SDL_StartTextInput()/SDL_StopTextInput()
as SDL3 no longer enables it by default. (#7452, #6306, #6071, #1953) [@Green-Sky]
- Examples: GLFW+Vulkan, SDL+Vulkan: Added optional support for Volk. (#6582, #4854)
- Examples: GLFW+WebGPU: Added support for WebGPU-native/Dawn (#7435, #7132) [@eliasdaler, @Zelif]
- Examples: GLFW+WebGPU: Renamed example_emscripten_wgpu/ to example_glfw_wgpu/. (#7435, #7132)
-----------------------------------------------------------------------
VERSION 1.90.5 (Released 2024-04-11)
-----------------------------------------------------------------------
Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.5
Breaking changes:
- More formally obsoleted GetKeyIndex() when IMGUI_DISABLE_OBSOLETE_FUNCTIONS is set.
It has been unnecessary and a no-op since 1.87 (it returns the same value as passed
when used with a 1.87+ backend using io.AddKeyEvent() function). (#4921)
- IsKeyPressed(GetKeyIndex(ImGuiKey_XXX)) --> IsKeyPressed(ImGuiKey_XXX)
- ImDrawList: Merged the radius_x/radius_y parameters in AddEllipse(), AddEllipseFilled()
and PathEllipticalArcTo() into a single ImVec2 parameter. Exceptionally, because those
functions were added recently in 1.90, we are not adding inline redirection functions.
The transition is easy and should affect few users. (#2743, #7417) [@cfillion]
Other changes:
- Windows: Scrollbar visibility decision uses current size when both size and contents
size are submitted by API. (#7252)
- Windows: Double-click to collapse may be disabled via key-ownership mechanism. (#7369)
- Windows: BeginChild(): Extend outer resize borders to the edges when there are no corner
grips. Essentially affects resizable child windows. (#7440, #1710) [@cfillion]
- Windows: BeginChild(): Resizing logic for child windows evaluates whether per-axis clamping
should be applied based on parent scrollbars, not child scrollbars. (#7440, #1710) [@cfillion]
Adjust those resizing limits to match window padding rather than inner clipping rectangle.
- Tables: Fixed auto-width columns when using synced-instances of same table, width of
one instance would bleed into next one instead of sharing their widths. (#7218)
- Tables: Angled headers: fixed border hit box extending beyond when used within
non-scrollable tables. (#7416) [@cfillion]
- Tables: Angled headers: fixed borders not moving back up after TableAngleHeadersRow()
stops being called. (#7416) [@cfillion]
- Tables: Angled headers: rounding header size to nearest integers, fixes some issues
when using clipper.
- Menus, Popups: Fixed an issue where sibling menu popups re-opening in successive
frames would erroneously close the window. While it is technically a popup issue
it would generally manifest when fast moving the mouse bottom to top in a sub-menu.
(#7325, #7287, #7063)
- ProgressBar: Fixed passing fraction==NaN from leading to a crash. (#7451)
- ListBox: Fixed text-baseline offset when using SameLine()+Text() after a labeled ListBox().
- Drags, Sliders, Inputs: Fixed io.PlatformLocaleDecimalPoint decimal point localization
feature not working regression from 1.90.1. (#7389, #6719, #2278) [@GamingMinds-DanielC]
- Style: Added ImGuiStyleVar_TabBorderSize, ImGuiStyleVar_TableAngledHeadersAngle for
consistency. (#7411) [@cfillion]
- DrawList: Added AddConcavePolyFilled(), PathFillConcave() concave filling. (#760) [@thedmd]
Note that only simple polygons (no self-intersections, no holes) are supported.
- DrawList: Allow AddText() to accept null ranges. (#3615, 7391)
- Docs: added more wiki links to headers of imgui.h/imgui.cpp to facilitate discovery
of interesting resources, because github doesn't allow Wiki to be crawled by search engines.
- This is the main wiki: https://github.com/ocornut/imgui/wiki
- This is the crawlable version: https://github-wiki-see.page/m/ocornut/imgui/wiki
Adding a link to the crawlable version, even though it is not intended for humans,
to increase its search rank.

VERSION 1.90.4 (Released 2024-02-22)
-----------------------------------------------------------------------
Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.4
Other changes:
- Nav: Fixed SetKeyboardFocusHere() or programmatic tabbing API from not working on
windows with the ImGuiWindowFlags_NoNavInputs flag (regression in 1.90.2, which
among other things broke imgui_memory_editor).
- Menus, Popups: Fixed an issue where hovering a parent-menu upward would
erroneously close the window. (#7325, #7287, #7063)
- Popups: Fixed resizable popup minimum size being too small. Standardized minimum
size logic. (#7329).
- Modals: Temporary changes of ImGuiCol_ModalWindowDimBg are properly handled by
BeginPopupModal(). (#7340)
- Tables: Angled headers: fixed support for multi-line labels. (#6917)
- Tables: Angled headers: various fixes to accurately handle CellPadding changes. (#6917)
- Tables: Angled headers: properly registers horizontal component of angled headers
for auto-resizing of columns. (#6917)
- Tables: Angled headers: fixed TableAngledHeadersRow() incorrect background fill
drawn too low, particularly visible with tables that have no scrolling. (#6917)
- ProgressBar: Fixed a minor tessellation issue when rendering rounded progress bars,
where in some situations the rounded section wouldn't follow regular tessellation rules.
- Debug Tools: Item Picker: Promoted ImGui::DebugStartItemPicker() to public API. (#2673)
- Debug Tools: Item Picker: Menu entry visible in Demo->Tools but greyed out unless
io.ConfigDebugIsDebuggerPresent is set. (#2673)
- Misc: Added optional alpha multiplier parameter to GetColorU32(ImU32) variant.
- Demo: Custom Rendering: better demonstrate PathArcTo(), PathBezierQuadraticCurveTo(),
PathBezierCubicCurveTo(), PathStroke(), PathFillConvex() functions.
-----------------------------------------------------------------------
VERSION 1.90.3 (Released 2024-02-14)
-----------------------------------------------------------------------
Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.3
Breaking changes:
- Backends: SDL2: Removed obsolete ImGui_ImplSDL2_NewFrame(SDL_Window*) signature which
was obsoleted in 1.84. Calling ImGui_ImplSDL2_NewFrame() is fine.
- Backends: Vulkan: Moved RenderPass parameter from ImGui_ImplVulkan_Init() function to
ImGui_ImplVulkan_InitInfo structure. Not required when using dynamic rendering. (#7308) [@shawnhatori]
- Backends: Vulkan: Using dynamic rendering now require filling the PipelineRenderingCreateInfo
structure in ImGui_ImplVulkan_InitInfo, allowing to configure color/depth/stencil formats.
Removed ColorAttachmentFormat field previously provided for dynamic rendering.
(#7166, #6855, #5446, #5037) [@shawnhatori]
Other changes:
- Menus, Popups: Fixed menus and popups with ChildWindow flag erroneously not displaying
a scrollbar when contents is over parent viewport size. (#7287, #7063) [@ZingBallyhoo]
- Backends: SDL2, SDL3: Handle gamepad disconnection + fixed increasing gamepad reference
counter continuously. Added support for multiple simultaneous gamepads.
Added ImGui_ImplSDL2_SetGamepadMode()) function to select whether to automatically pick
first available gamepad, all gamepads, or specific gamepads.
(#3884, #6559, #6890, #7180) [@ocornut, @lethal-guitar, @wn2000, @bog-dan-ro]
- Backends: SDL3: Fixed gamepad handling. (#7180) [@bog-dan-ro]
- Backends: SDLRenderer3: query newly added SDL_RenderViewportSet() to not restore
a wrong viewport if none was initially set.
- Backends: DirectX9: Using RGBA format when allowed by the driver to avoid CPU side
conversion. (#6575) [@Demonese]
- Internals: Fixed ImFileOpen not working before context is created, preventing creation
of a font atlas before main context creation. (#7314, #7315) [@PathogenDavid, @ocornut]
-----------------------------------------------------------------------
VERSION 1.90.2 (Released 2024-02-09)
-----------------------------------------------------------------------
Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.2
Breaking changes:
- Commented out ImGuiIO::ImeWindowHandle obsoleted in 1.87 in favor of writing
to 'void* ImGuiViewport::PlatformHandleRaw'.
- Backends: WebGPU: ImGui_ImplWGPU_Init() now takes a ImGui_ImplWGPU_InitInfo structure
instead of variety of parameters, allowing for easier further changes. (#7240)
Other changes:
- Nav: keyboard/gamepad activation mark widgets as held to give better visual feedback.
- Nav: tweak to logic marking navigated item as hovered when using keyboard, allowing
the hover highlight to stay even while another item is activated.
- Nav: Fixed SetKeyboardFocusHere() not working when current nav focus is in different scope,
regression from 1.90.1 related to code scoping Tab presses to local scope. (#7226) [@bratpilz]
- Nav: Fixed pressing Escape while in a child window with _NavFlattened flag. (#7237)
- Nav: Improve handling of Alt key to toggle menu so that key ownership may be claimed on
individual left/right alt key without interfering with the other.
- Nav, Menus: Fixed click on a BeginMenu() followed by right-arrow from making the child menu
reopen and flicker (using ImGuiPopupFlags_NoReopen).
- Nav: ImGuiWindowFlags_NoNavInputs is tested during scoring so NavFlattened windows can use it.
- Popups: OpenPopup(): added ImGuiPopupFlags_NoReopen flag to specifically not close and reopen
a popup when it is already open. (#1497, #1533)
(Note that this differs from specific handling we already have in place for the case of calling
OpenPopup() repeatedly every frame: we already didn't reopen in that specific situation, otherwise
the effect would be very disastrous in term of confusion, as reopening would steal focus).
- Popups: Slight change to popup closing logic (e.g. after focusing another window) which skipped
over popups that are also child windows.
- Combo: Fixed not reusing windows optimally when used inside a popup stack.
- Debug Tools: Metrics: Fixed debug break in SetShortcutRouting() not handling ImGuiMod_Shortcut redirect.
- Debug Tools: Metrics: Improved Monitors and Viewports minimap display. Highlight on hover.
- Debug Tools: Debug Log: Added "Input Routing" logging.
- Debug Tools: Added "nop" to IM_DEBUG_BREAK macro on GCC to work around GDB bug (#7266) [@Peter0x44]
- Backends: Vulkan: Fixed vkAcquireNextImageKHR() validation errors in VulkanSDK 1.3.275 by
allocating one extra semaphore than in-flight frames. (#7236) [@mklefrancois]
- Backends: Vulkan: Fixed vkMapMemory() calls unnecessarily using full buffer size. (#3957)
- Backends: Vulkan: Fixed handling of ImGui_ImplVulkan_InitInfo::MinAllocationSize field. (#7189, #4238)
- Backends: WebGPU: Added ImGui_ImplWGPU_InitInfo::PipelineMultisampleState. (#7240)
- Backends: WebGPU: Filling all WGPUDepthStencilState fields explicitly as a recent Dawn
update stopped setting default values. (#7232) [@GrigoryGraborenko]
- Backends: WebGPU: Fixed pipeline layout leak. (#7245) [@rajveermalviya]
- Backends: OpenGL3: Backup and restore GL_PIXEL_UNPACK_BUFFER. (#7253)
- Internals: Many improvements related to yet unpublicized shortcut routing and input ownership systems.
- Internals: InputText: Added internal helpers to force reload of user-buf when active. (#2890) [@kudaba, @ocornut]
Often requested in some form (#6962, #5219, #3290, #4627, #5054, #3878, #2881, #1506, #1216, #968),

VERSION 1.90.1 (Released 2024-01-10)
-----------------------------------------------------------------------
Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90.1
Breaking changes:
- imgui_freetype: commented out ImGuiFreeType::BuildFontAtlas() obsoleted in 1.81.
Prefer using #define IMGUI_ENABLE_FREETYPE or see commented code for manual calls.
- Removed CalcListClipping() marked obsolete in 1.86. (#3841)
Prefer using ImGuiListClipper which can return non-contiguous ranges.
- Internals, Columns: commented out legacy ImGuiColumnsFlags_XXX symbols redirecting
to ImGuiOldColumnsFlags_XXX, obsoleted from imgui_internal.h in 1.80.
- Commented out obsolete ImGuiKey_KeyPadEnter redirection to ImGuiKey_KeypadEnter. (#2625, #7143)
Other changes:
- Windows:
- BeginChild(): Fixed auto-resizing erroneously limiting size to host viewport
minus padding. There are no limit to a child width/height. (#7063) [@Devyre]
- BeginChild(): Resize borders rendered even when ImGuiWindowFlags_NoBackground
is specified. (#1710, #7194)
- Fixed some auto-resizing path using style.WindowMinSize.x (instead of x/y)
for both axises since 1.90. (#7106) [@n0bodysec]
- Scrolling: internal scrolling value is rounded instead of truncated, as a way to reduce
speed asymmetry when (incorrectly) attempting to scroll by non-integer amount. (#6677)
- Navigation (Keyboard/gamepad):
- Nav, IO: SetNextFrameWantCaptureKeyboard(false) calls are not overridden back to true when
navigation is enabled. SetNextFrameWantCaptureKeyboard() is always higher priority. (#6997)
- Nav: Activation can also be performed with Keypad Enter. (#5606)
- Drag and Drop:
- Fixed drop target highlight on items temporarily pushing a widened clip rect
(namely Selectables and Treenodes using SpanAllColumn flag) so the highlight properly covers
all columns. (#7049, #4281, #3272)
- InputText:
- InputTextMultiline: Fixed Tab character input not repeating (1.89.4 regression).
- InputTextMultiline: Tabbing through a multi-line text editor which allows Tab character inputs
(using the ImGuiInputTextFlags_AllowTabInput flag) doesn't automatically activate it, in order
to allow passing through multiple widgets easily. (#3092, #5759, #787)
- Drags, Sliders, Inputs:
- DragScalarN, SliderScalarN, InputScalarN: Fixed incorrect pushes into ItemWidth
stack when number of components is 1. [#7095] [@Nahor]
- Drags, Sliders, Inputs: removed all attempts to filter non-numerical characters during text
editing. Invalid inputs not applied to value, visibly reverted after validation. (#6810, #7096)
- Drags, Sliders, Inputs: removal of filter means that "nan" and "inf" values may be input. (#7096)
- DragScalarN, SliderScalarN, InputScalarN, PushMultiItemsWidths: improve multi-components
width computation to better distribute the error. (#7120, #7121) [@Nahor]
- Menus:
- Tweaked hover slack logic, adding an extra timeout to avoid situations where a slow vertical
movements toward another parent BeginMenu() can keep the wrong child menu open. (#6671, #6926)
- Color Editors:
- ColorEdit: Layout tweaks for very small sizes. (#7120, #7121)
- ColorPicker: Fixed saturation/value cursor radius not scaling properly.
- Tabs: Added ImGuiTabItemFlags_NoAssumedClosure to enable app to react on closure attempt,
without having to draw an unsaved document marker (ImGuiTabItemFlags_UnsavedDocument sets
_NoAssumedClosure automatically). (#7084)
- Debug Tools:
- Added io.ConfigDebugIsDebuggerPresent option. When enabled, this adds buttons in various
locations of Metrics/Debugger to manually request a debugger break:
- Request a debug break in a Begin() call.
- Request a debug break in a ItemAdd() call via debug log and hovering 0xXXXXXX identifiers.
- Request a debug break in a BeginTable() call.
- Request a debug break in a SetShortcutRouting()/Shortcut() call. [Internal]
- Metrics: Reorganize Tools menu.
- Added DebugFlashStyleColor() to identify a style color. Added to Style Editor.
- Debug Log: Hide its own clipper log to reduce noise in the output. (#5855)
- Debug Log: Clicking any filter with SHIFT held enables it for 2 frames only,
making it easier when dealing with spammy logs. (#5855)
- Settings: Fixed an issue marking settings as dirty when merely clicking on a border or resize
grip without moving it.
- Misc: Added IMGUI_USER_H_FILENAME to change the path included when using
IMGUI_INCLUDE_IMGUI_USER_H. (#7039) [@bryceberger]
- Misc: Rework debug display of texture id in Metrics window to avoid compile-error when
ImTextureID is defined to be larger than 64-bits. (#7090)
- Misc: Added extra courtesy ==/!= operators when IMGUI_DEFINE_MATH_OPERATORS is defined.
- Misc: Fixed text functions fast-path for handling "%s" and "%.*s" to handle null pointers gracefully,
like most printf implementations. (#7016, #3466, #6846) [@codefrog2002]
- Misc: Renamed some defines in imstb_textedit.h to avoid conflicts when using unity/jumbo builds
on a codebase where another copy of the library is used.
- Misc: During shutdown, check that io.BackendPlatformUserData and io.BackendRendererUserData are NULL
in order to catch cases where backend was not shut down. (#7175)
- Misc: Reworked Issue Template to a shinier and better form. (#5927) [@Panquesito7, @PathogenDavid, @ocornut]
- Backends:
- GLFW, Emscripten: Added ImGui_ImplGlfw_InstallEmscriptenCanvasResizeCallback() to
register canvas selector and auto-resize GLFW window. (#6751) [@Traveller23, @ypujante]
- GLFW: Fixed Windows specific hooks to use Unicode version of WndProc even when
compiling in MBCS mode. (#7174) [@kimidaisuki22]
- OpenGL3: Update GL3W based imgui_impl_opengl3_loader.h to load libGL.so variants in
case of missing symlink. Fix 1.90 regression for some distros. (#6983)
- Vulkan: Fixed mismatching allocator passed to vkCreateCommandPool() vs
vkDestroyCommandPool(). (#7075) [@FoonTheRaccoon]
- Vulkan: Added MinAllocationSize field in ImGui_ImplVulkan_InitInfo to workaround zealous
"best practice" validation layer. (#7189, #4238) [@philae-ael]
- Vulkan: Stopped creating command pools with VK_COMMAND_POOL_CREATE_RESET_COMMAND_BUFFER_BIT
as we don't reset them.
- WebGPU: Fixed wgpuRenderPassEncoderSetScissorRect() crash when rendering modal window's
dimming layer, which has an unclipped value in ImDrawCmd::ClipRect. (#7191) [@aparis69]
- Examples:
- Examples: GLFW+Emscripten: Fixed examples not consistently resizing according to host canvas.
(#6751) [@Traveller23, @ypujante]
- Examples: SDL3: Minor fixes following recent SDL3 in-progress development.
-----------------------------------------------------------------------
VERSION 1.90.0 (Released 2023-11-15)
-----------------------------------------------------------------------
Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.90
Breaking changes:
- BeginChild(): Upgraded 'bool border = false' parameter to 'ImGuiChildFlags flags = 0'.
Added ImGuiChildFlags_Border value. As with our prior "bool-to-flags" API updates,
the ImGuiChildFlags_Border value is guaranteed to be == true forever to ensure a
smoother transition, meaning all existing calls will still work.
If you want to neatly transition your call sites:
Before: BeginChild("Name", size, true)
After: BeginChild("Name", size, ImGuiChildFlags_Border)
Before: BeginChild("Name", size, false)
After: BeginChild("Name", size) or BeginChild("Name", 0) or BeginChild("Name", size, ImGuiChildFlags_None)
Existing code will still work as 'ImGuiChildFlags_Border == true', but you are encouraged to update call sites.
- BeginChild(): Added child-flag ImGuiChildFlags_AlwaysUseWindowPadding as a replacement for
the window-flag ImGuiWindowFlags_AlwaysUseWindowPadding: the feature only ever made sense
for use with BeginChild() anyhow, passing it to Begin() had no effect. Now that we accept
child-flags we are moving it there. (#462)
Before: BeginChild("Name", size, 0, ImGuiWindowFlags_AlwaysUseWindowPadding);
After: BeginChild("Name", size, ImGuiChildFlags_AlwaysUseWindowPadding, 0);
Kept inline redirection enum (will obsolete later) so existing code will work.
- BeginChildFrame()/EndChildFrame(): removed functions in favor of using BeginChild() with
the ImGuiChildFlags_FrameStyle flag. Kept inline redirection function (will obsolete).
Those functions were merely PushStyle/PopStyle helpers and custom versions are easy to create.
(The removal isn't so much motivated by needing to add the feature in BeginChild(), but by the
necessity to avoid BeginChildFrame() signature mismatching BeginChild() signature and features.)
- Debug Tools: Renamed ShowStackToolWindow() ("Stack Tool") to ShowIDStackToolWindow() ("ID Stack Tool"),
as earlier name was misleading. Kept inline redirection function. (#4631)
- IO: Removed io.MetricsActiveAllocations introduced in 1.63, was displayed in Metrics and unlikely to
be accessed by end-user. Value still visible in the UI and easily to recompute from a delta.
- Defining IMGUI_DISABLE_OBSOLETE_FUNCTIONS now automatically defines IMGUI_DISABLE_OBSOLETE_KEYIO. (#4921)
- Removed IM_OFFSETOF() macro in favor of using offsetof() available in C++11. Kept redirection define. (#4537)
- ListBox, Combo: Changed signature of "name getter" callback in old one-liner ListBox()/Combo() apis.
Before:
getter type: bool (*getter)(void* user_data, int idx, const char** out_text)
function: bool Combo(const char* label, int* current_item, bool (*getter)(void* user_data, int idx, const char** out_text), ...);
function: bool ListBox(const char* label, int* current_item, bool (*getting)(void* user_data, int idx, const char** out_text), ...);
After:
getter type: const char* (*getter)(void* user_data, int idx)
function: bool Combo(const char* label, int* current_item, const char* (*getter)(void* user_data, int idx), ...);
function: bool ListBox(const char* label, int* current_item, const char* (*getter)(void* user_data, int idx), ...);
Old type was unnecessarily complex and harder to wrap in e.g. a lambda. Kept inline redirection function (will obsolete).
- Commented out obsolete redirecting enums/functions that were marked obsolete two years ago:
- GetWindowContentRegionWidth() -> use GetWindowContentRegionMax().x - GetWindowContentRegionMin().x.
Consider that generally 'GetContentRegionAvail().x' is often more correct and more useful.
- ImDrawCornerFlags_XXX -> use ImDrawFlags_RoundCornersXXX names.
Read 1.82 changelog for details + grep commented names in sources.
- Commented out runtime support for hardcoded ~0 or 0x01..0x0F rounding flags values for
AddRect()/AddRectFilled()/PathRect()/AddImageRounded(). -> Use ImDrawFlags_RoundCornersXXX flags.
Read 1.82 changelog for details.
- Backends: Vulkan: Removed parameter from ImGui_ImplVulkan_CreateFontsTexture(): backend now creates its own
command-buffer to upload fonts. Removed ImGui_ImplVulkan_DestroyFontUploadObjects() which is now unnecessary.
No need to call ImGui_ImplVulkan_CreateFontsTexture() as it is done automatically in ImGui_ImplVulkan_NewFrame().
You can call ImGui_ImplVulkan_CreateFontsTexture() manually if you need to reload the font atlas texture.
(#6943, #6715, #6327, #3743, #4618)
Other changes:
- Windows:
- BeginChild(): Added ImGuiChildFlags_ResizeX and ImGuiChildFlags_ResizeY to allow resizing
child windows from the bottom/right border (toward layout direction). Resized child windows
settings are saved and persistent in .ini file. (#1710)
- BeginChild(): Added ImGuiChildFlags_Border as a replacement for 'bool border = true' parameter.
- BeginChild(): Added ImGuiChildFlags_AutoResizeX and ImGuiChildFlags_AutoResizeY to auto-resize
on one axis, while generally providing a size on the other axis. (#1666, #1395, #1496, #1710)
e.g. BeginChild("name", {-FLT_MIN, 0.0f}, ImGuiChildFlags_AutoResizeY);
- Size is only reevaluated if the child window is within visible boundaries or just appearing.
This allows coarse clipping to be performed and auto-resizing childs to return false when
hidden because of being scrolled out.
- Combining this with also specifying ImGuiChildFlags_AlwaysAutoResize disables
this optimization, meaning child contents will never be clipped (not recommended).
- Please be considerate that child are full windows and carry significant overhead:
combining auto-resizing for both axises to create a non-scrolling child to merely draw
a border would be better more optimally using BeginGroup(). (see #1496)
(until we come up with new helpers for framed groups and work-rect adjustments).
- BeginChild(): made it possible to use SetNextWindowSizeConstraints() rectangle, often
useful when ImGuiChildFlags_AutoResizeX or ImGuiChildFlags_AutoResizeY. (#1666, #1395, #1496)
Custom constraint callback are not supported with child window.
- BeginChild(): Added ImGuiChildFlags_FrameStyle as a replacement for BeginChildFrame(),
use it to make child window use FrameBg, FrameRounding, FrameBorderSize, FramePadding
instead of ChildBg, ChildRounding, ChildBorderSize, WindowPadding.
- Popups: clarified meaning of 'p_open != NULL' in BeginPopupModal() + set back user value
to false when popup is closed in ways other than clicking the close button. (#6900)
- Double-clicking lower-left resize grip auto-resize (like lower-right one).
- Double-clicking bottom or right window border auto-resize on a singles axis.
- Use relative mouse movement for border resize when the border geometry has moved
(e.g. resizing a child window triggering parent scroll) in order to avoid resizing
feedback loops. Unless manually mouse-wheeling while border resizing. (#1710)
- Separators:
- Altered end-points to use more standard boundaries. (#205, #4787, #1643)
Left position is always current cursor X position, right position is always work-rect
rightmost edge. It effectively means that:
- A separator in the root of a window will end up a little more distant from edges
than previously (essentially following WindowPadding instead of clipping edges).
- A separator inside a table cell end up a little distance from edges instead of
touching them (essentially following CellPadding instead of clipping edges).
- Matches tree indentation (was not the case before).
- Matches SeparatorText(). (#1643)
- Makes things correct inside groups without specific/hard-coded handling. (#205)
- Support legacy behavior when used inside old Columns(), as we favored that idiom back then,
only different is left position follows indentation level, to match calling a Separator()
inside or outside Columns().
- Tooltips:
- Made using SetItemTooltip()/IsItemHovered(ImGuiHoveredFlags_ForTooltip) defaults to
activate tooltips on disabled items. This is done by adding ImGuiHoveredFlags_AllowWhenDisabled
to the default value of style.HoverFlagsForTooltipMouse/HoverFlagsForTooltipNav. (#1485)
- Made is possible to combine ImGuiHoveredFlags_ForTooltip with a ImGuiHoveredFlags_DelayXXX
override. (#1485)
- Drag and Drop:
- Reworked drop target highlight: reduce rectangle to its visible portion, and then expand
slightly. A full rectangle is always visible and it may protrude slightly. (#4281, #3272)
- Fixed submitting a tooltip from drop target location when using AcceptDragDropPayload()
with ImGuiDragDropFlags_AcceptNoPreviewTooltip and submitting a tooltip manually.
- Tables:
- Added angled headers support. You need to set ImGuiTableColumnFlags_AngledHeader on selected
columns and call TableAngledHeadersRow(). Added style.TableAngledHeadersAngle style option. (#6917)
- Added ImGuiTableFlags_HighlightHoveredColumn flag, currently highlighting column header.
- Fixed an edge-case when no columns are visible + table scrollbar is visible + user
code is always testing return value of TableSetColumnIndex() to coarse clip. With an active
clipper it would have asserted. Without a clipper, the scrollbar range would be wrong.
- Request user to submit contents when outer host-window is requesting auto-resize,
so a scrolling table can contribute to initial window size. (#6510)
- Fixed subtle drawing overlap between borders in some situations.
- Fixed bottom-most and right-most outer border offset by one. (#6765, #3752) [@v-ein]
- Fixed top-most and left-most outer border overlapping inner clip-rect when scrolling. (#6765)
- Fixed top-most outer border being drawn with both TableBorderLight and TableBorderStrong
in some situations, causing the earlier to be visible underneath when alpha is not 1.0f.
- Fixed right-clicking right-most section (past right-most column) from highlighting a column.
- Fixed an issue with ScrollX enabled where an extraneous draw command would be created.
- Menus:
- Menus: Fixed a bug where activating an item in a child-menu and dragging mouse over the
parent-menu would erroneously close the child-menu. (Regression from 1.88). (#6869)
- MenuBar: Fixed an issue where layouting an item in the menu-bar would erroneously
register contents size in a way that would affect the scrolling layer.
Was most often noticeable when using an horizontal scrollbar. (#6789)
- InputText:
- InputTextMultiline: Fixed a crash pressing Down on last empty line of a multi-line buffer.
(regression from 1.89.2, only happened in some states). (#6783, #6000)
- InputTextMultiline: Fixed Tabbing cycle leading to a situation where Enter key wouldn't
be accepted by the widget when navigation highlight is visible. (#6802, #3092, #5759, #787)
- Nav: Tabbing always enable nav highlight when ImGuiConfigFlags_NavEnableKeyboard is set.
Previously was inconsistent and only enabled when stepping through a non-input item.
(#6802, #3092, #5759, #787)
- TreeNode: Added ImGuiTreeNodeFlags_SpanAllColumns for use in tables. (#3151, #3565, #2451, #2438)
- TabBar: Fixed position of unsaved document marker (ImGuiTabItemFlags_UnsavedDocument) which was
accidentally offset in 1.89.9. (#6862) [@alektron]
- ColorPicker4(): Fixed ImGuiColorEditFlags_NoTooltip not being forwarded to individual DragFloat3
sub-widgets which have a visible color preview when ImGuiColorEditFlags_NoSidePreview is also set. (#6957)
- BeginGroup(): Fixed a bug pushing line lower extent too far down when called after a call
to SameLine() followed by manual cursor manipulation.
- BeginCombo(): Added ImGuiComboFlags_WidthFitPreview flag. (#6881) [@mpv-enjoyer]
- BeginListBox(): Fixed not consuming SetNextWindowXXX() data when returning false.
- Fonts:
- Argument 'float size_pixels' passed to AddFontXXX() functions is now rounded to lowest integer.
This is because our layout/font system currently doesn't fully support non-integer sizes. Until
it does, this has been a common pitfall leading to more or less subtle issues. (#3164, #3309, #6800)
- Better assert during load when passing truncated font data or wrong data size. (#6822)
- Ensure calling AddFontXXX function doesn't invalidates ImFont's ConfigData pointers
prior to building again. (#6825)
- Added ImFontConfig::RasterizerDensity field to increase texture size of rendered glyphs
without altering other metrics. Among other things, this makes it easier to have zooming code
swapping between 2 fonts (e.g. a 100% and a 400% fonts) depending on current scale. (#6925) [@thedmd]
Important: if you increase this it is expected that you would render the font with a scale of
similar value or magnitude. Merely increasing this without increasing scale may lower quality.
- imgui_freetype: Added support for RasterizerDensity. (#6925) [@thedmd]
- imgui_freetype: Fixed a warning and leak in IMGUI_ENABLE_FREETYPE_LUNASVG support. (#6842, #6591)
- Inputs: Added IsKeyChordPressed() helper function e.g. IsKeyChordPressed(ImGuiMod_Ctrl | ImGuiKey_S).
(note that ImGuiMod_Shortcut may be used as an alias for Cmd on OSX and Ctrl on other systems).
- Misc: Most text functions also treat "%.*s" (along with "%s") specially to bypass formatting. (#3466, #6846)
- IO: Add extra keys to ImGuiKey enum: ImGuiKey_F13 to ImGuiKey_F24. (#6891, #4921)
- IO: Add extra keys to ImGuiKey enum: ImGuiKey_AppBack, ImGuiKey_AppForward. (#4921)
- IO: Setting io.WantSetMousePos ignores incoming MousePos events. (#6837, #228) [@bertaye]
- Debug Tools: Metrics: Added log of recent alloc/free calls.
- Debug Tools: Metrics: Added "Show groups rectangles" in tools.
- ImDrawList: Added AddEllipse(), AddEllipseFilled(), PathEllipticalArcTo(). (#2743) [@Doohl]
- ImVector: Added find_index() helper.
- Demo: Added "Drag and Drop -> Tooltip at target location" demo.
- Demo: Added "Layout -> Child Windows -> Manual-resize" demo. (#1710)
- Demo: Added "Layout -> Child Windows -> Auto-resize with constraints" demo. (#1666, #1395, #1496, #1710)
- Demo: Partly fixed "Examples -> Constrained-resizing window" custom constrains demo. (#6210) [@cfillion]
- Backends: Vulkan: Removed parameter from ImGui_ImplVulkan_CreateFontsTexture(): backend now creates its own
command-buffer to upload fonts. Removed ImGui_ImplVulkan_DestroyFontUploadObjects() which is now unnecessary.
No need to call ImGui_ImplVulkan_CreateFontsTexture() as it is done automatically in ImGui_ImplVulkan_NewFrame().
You can call ImGui_ImplVulkan_CreateFontsTexture() manually if you need to reload font atlas texture.
Fixed leaks, and added ImGui_ImplVulkan_DestroyFontsTexture() (probably no need to call this directly).

VERSION 1.89.9 (Released 2023-09-04)
-----------------------------------------------------------------------
Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.89.9
Breaking changes:
- Clipper: Renamed IncludeRangeByIndices(), also called ForceDisplayRangeByIndices()
before 1.89.6, to IncludeItemsByIndex(). Kept inline redirection function. (#6424, #3841)
Other changes:
- Tables: Made it possible to use SameLine(0,0) after TableNextColumn() or
TableSetColumnIndex() in order to reuse line pos/height from previous cell. (#3740)
- Tables: Made it possible to change style.CellPadding.y between rows. (#3740)
- Nav, TreeNode: Pressing Left with ImGuiTreeNodeFlags_NavLeftJumpsBackHere now goes
through proper navigation logic: honor scrolling and selection. (#1079, #1131)
- Sliders: Fixed an integer overflow and div-by-zero in SliderInt() when
v_max=INT_MAX (#6675, #6679) [@jbarthelmes]
- Windows: Layout of Close/Collapse buttons uses style.ItemInnerSpacing.x between items,
stopped incorrectly using FramePadding in a way where hit-boxes could overlap when
setting large values. (#6749)
- TabBar, Style: added style.TabBarBorderSize and associated ImGuiStyleVar_TabBarBorderSize.
Tweaked rendering of that separator to allow thicker values. (#6820, #4859, #5022, #5239)
- InputFloat, SliderFloat, DragFloat: always turn both '.' and ',' into the current decimal
point character when using Decimal/Scientific character filter. (#6719, #2278) [@adamsepp]
- ColorEdit, ColorPicker: Manipulating options popup don't mark item as edited. (#6722)
(Note that they may still be marked as Active/Hovered.)
- Clipper: Added IncludeItemByIndex() helper to include a single item. (#6424, #3841)
- Clipper: Fixed a bug if attempt to force-include a range which matches an already
included range, clipper would end earlier. (#3841)
- ImDrawData: Fixed an issue where TotalVtxCount/TotalIdxCount does not match the sum
of individual ImDrawList's buffer sizes when a dimming/modal background is rendered. (#6716)
- ImDrawList: Automatically calling ChannelsMerge() if not done after a split.
- ImDrawList: Fixed OOB access in _CalcCircleAutoSegmentCount when passing excessively
large radius to AddCircle(). (#6657, #5317) [@EggsyCRO, @jdpatdiscord]
- IO: Exposed io.PlatformLocaleDecimalPoint to configure decimal point ('.' or ',') for
languages needing it. Should ideally be set to the value of '*localeconv()->decimal_point'
but our backends don't do it yet. (#6719, #2278)
- IO: Fixed io.AddMousePosEvent() and io.AddMouseButtonEvent() writing MouseSource to
wrong union section. Was semantically incorrect and accidentally had no side-effects
with default compiler alignment settings. (#6727) [@RickHuang2001]
- Misc: Made multiple calls to Render() during the same frame early out faster.
- Debug Tools: Metrics: Fixed "Drawlists" section and per-viewport equivalent
appearing empty (regression in 1.89.8).
- Demo: Reorganized "Examples" menu.
- Demo: Tables: Demonstrate using SameLine() between cells. (#3740)
- Demo: Tables: Demonstrate altering CellPadding.y between rows. (#3740)
- Demo: Custom Rendering: Demonstrate out-of-order rendering using ImDrawListSplitter.
- Backends: SDL2,SDL3: added ImGui_ImplSDL2_InitForOther()/ImGui_ImplSDL3_InitForOther()
for consistency (matching GLFW backend) and as most initialization paths don't actually
need to care about rendering backend.

framebuffer format. (#6640, #6748) [@smileorigin]
-----------------------------------------------------------------------
VERSION 1.89.8 (Released 2023-08-01)
-----------------------------------------------------------------------
Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.89.8
Breaking changes:
- IO: Obsoleted io.ClearInputCharacters() (added in 1.47) as it now ambiguous
and often incorrect/misleading considering the existence of a higher-level
input queue. This is automatically cleared by io.ClearInputsKeys(). (#4921)
- ImDrawData: CmdLists[] array is now owned, changed from 'ImDrawList**' to
'ImVector<ImDrawList*>'. Majority of users shouldn't be affected, but you
cannot compare to NULL nor reassign manually anymore.
Instead use AddDrawList(). Allocation count are identical. (#6406, #4879, #1878)
Other changes:
- Fonts: ImFontConfig::OversampleH now defaults to 2 instead of 3, since the
quality increase is largely minimal.
- Fonts, imgui_freetype: Added support to render OpenType SVG fonts using lunasvg.
Requires enabling IMGUI_ENABLE_FREETYPE_LUNASVG along with IMGUI_ENABLE_FREETYPE,
and providing headers/libraries for lunasvg. (#6591, #6607) [@sakiodre]
- ImDrawData: CmdLists[] array is now an ImVector<> owned by ImDrawData rather
than a pointer to internal state.
- This makes it easier for user to create their own or append to an existing draw data.
Added a ImDrawData::AddDrawList() helper function to do that. (#6406, #4879, #1878)
- This makes it easier to perform a deep-swap instead of a deep-copy, as array
ownership is now clear. (#6597, #6475, #6167, #5776, #5109, #4763, #3515, #1860)
- Syntax and allocation count are otherwise identical.
- Fixed CTRL+Tab dimming background assert when target window has a callback
in the last ImDrawCmd. (#4857, #5937)
- IsItemHovered: Fixed ImGuiHoveredFlags_ForTooltip for Keyboard/Gamepad navigation,
got broken prior to 1.89.7 due to an unrelated change making flags conflict. (#6622, #1485)
- InputText: Fixed a case where deactivation frame would write to underlying
buffer or call CallbackResize although unnecessary, in a frame where the
return value was false.
- Tables: fixed GetContentRegionAvail().y report not taking account of lower cell
padding or of using ImGuiTableFlags_NoHostExtendY. Not taking it into account
would make the idiom of creating vertically bottom-aligned content (e.g. a child
window) inside a table make the parent window erroneously have a scrollbar. (#6619)
- Tables: fixed calculation of multi-instance shared decoration/scrollbar width of
scrolling tables, to avoid flickering width variation when resizing down a table
hosting a child window. (#5920, #6619)
- Scrollbar: layout needs to take account of window border size, so a border size
will slightly reduce scrollbar size. Generally we tried to make it that window
border size has no incidence on layout but this can't work with thick borders. (#2522)
- IO: Added io.ClearEventsQueue() to clear incoming inputs events. (#4921)
May be useful in conjunction with io.ClearInputsKeys() if you need to clear
both current inputs state and queued events (e.g. when using blocking native
dialogs such as Windows's ::MessageBox() or ::GetOpenFileName()).
- IO: Changed io.ClearInputsKeys() specs to also clear current frame character buffer
(what now obsoleted io.ClearInputCharacters() did), as this is effectively the
desirable behavior.
- Misc: Added IMGUI_DISABLE_STB_SPRINTF_IMPLEMENTATION config macro to disable
stb_sprintf implementation when using IMGUI_USE_STB_SPRINTF. (#6626) [@septag]

- 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
@ -49,16 +46,16 @@ 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.
- **Please INCLUDE CODE. 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, explain it and fix it**. Please test your shortened code to ensure it exhibits the problem. **Often while creating the MCVE you will solve 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.
- **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.

## 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 pointing toward a problem, and 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 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).

**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.)

Your renderer backend 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 **can if your texture atlas is too big**. Also see [docs/FONTS.md](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md).

### 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.
Read the [docs/FONTS.md](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md) file for more details about icons font loading.
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.

## Troubleshooting
## Readme First
**A vast majority of font and text related issues encountered comes from 4 things:**
**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.
### (1) Invalid filename due to use of `\` or unexpected working directory.
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.
See [About Filenames](#about-filenames). AddFontXXX functions should assert if the filename is incorrect.
### (2) Invalid UTF-8 encoding of your non-ASCII strings.
See [About UTF-8 Encoding](#about-utf-8-encoding). Use the encoding viewer to confirm encoding of string literal in your source code is correct.
### (3) Missing glyph ranges.
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 [Debug Tools](#debug-tools) confirm loaded fonts and loaded glyph ranges.
This 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()`.
### (4) Font atlas texture fails to upload to GPU.
This is often of byproduct of point 3. If you have 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 or everything appears as empty black or 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:
- You may reduce oversampling, e.g. `font_config.OversampleH = 1`, this will half your texture size for a quality loss.
Note that while OversampleH = 2 looks visibly very close to 3 in most situations, with OversampleH = 1 the quality drop will be noticeable. Read about oversampling [here](https://github.com/nothings/stb/blob/master/tests/oversample).
- 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!
- Set `io.Fonts.Flags |= ImFontAtlasFlags_NoPowerOfTwoHeight;` to disable rounding the texture height to the next power of two.
- Set `io.Fonts.TexDesiredWidth` to specify a texture width to reduce maximum texture height (see comment in `ImFontAtlas::Build()` function).
**If you use custom glyphs ranges, make sure the array is persistent** and available during the calls to `GetTexDataAsAlpha8()/GetTexDataAsRGBA32()/Build()`.

## 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");
```
![UTF-8 Encoding viewer](https://github.com/ocornut/imgui/assets/8225057/61c1696a-9a94-46c5-9627-cf91211111f0)
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.

**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.
## Loading Font Data from Memory
Some solutions:
```cpp
ImFont* font = io.Fonts->AddFontFromMemoryTTF(data, data_size, size_pixels, ...);
```
IMPORTANT: `AddFontFromMemoryTTF()` by default transfer ownership of the data buffer to the font atlas, which will attempt to free it on destruction.
This was to avoid an unnecessary copy, and is perhaps not a good API (a future version will redesign it).
If you want to keep ownership of the data and free it yourself, you need to clear the `FontDataOwnedByAtlas` field:
```cpp
ImFontConfig font_cfg;
font_cfg.FontDataOwnedByAtlas = false;
ImFont* font = io.Fonts->AddFontFromMemoryTTF(data, data_size, size_pixels, &font_cfg);
```
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`.

- 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 char8_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");
```
However, you can disable this behavior completely using the compiler option [`/Zc:char8_t-`](https://learn.microsoft.com/en-us/cpp/build/reference/zc-char8-t?view=msvc-170) for MSVC and [`-fno-char8_t`](https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p1423r3.html) for Clang and GCC.

## 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.

### 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. You may also create your own backend. Anywhere where you can render textured triangles, you can render Dear ImGui.

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-20240105.zip](https://www.dearimgui.com/binaries/imgui-demo-binaries-20240105.zip) (Windows, 1.90.1 WIP, built 2024/01/05, 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
See the [Getting Started](https://github.com/ocornut/imgui/wiki/Getting-Started) guide for details.
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.
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 the [Getting Started](https://github.com/ocornut/imgui/wiki/Getting-Started) guide 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!**

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."

- 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).

// - If the file cannot be loaded, the function will return a nullptr. Please handle those errors in your application (e.g. use an assertion, or display an error and quit).
// - The fonts will be rasterized at a given size (w/ oversampling) and stored into a texture when calling ImFontAtlas::Build()/GetTexDataAsXXXX(), which ImGui_ImplXXXX_NewFrame below will call.
// - Use '#define IMGUI_ENABLE_FREETYPE' in your imconfig file to use Freetype for higher quality font rendering.

// - If the file cannot be loaded, the function will return a nullptr. Please handle those errors in your application (e.g. use an assertion, or display an error and quit).
// - The fonts will be rasterized at a given size (w/ oversampling) and stored into a texture when calling ImFontAtlas::Build()/GetTexDataAsXXXX(), which ImGui_ImplXXXX_NewFrame below will call.
// - Use '#define IMGUI_ENABLE_FREETYPE' in your imconfig file to use Freetype for higher quality font rendering.

// - Remember that in C/C++ if you want to include a backslash \ in a string literal you need to write a double backslash \\ !
