WHEN TO UPDATE?
- Keeping your copy of Dear ImGui updated regularly is recommended.
- 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.
- 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.
HOW TO UPDATE?
- 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.
- 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.
- 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 dropping this repository in your codebase, please leave the demo and text files in there, they will be useful.
- If you are copying this repository in your codebase, please leave the demo and documentations 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 1.90.1 (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.
- 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.
- 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 1.89.8 (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]
- Misc: Avoid stb_textedit.h reincluding string.h while in a namespace, which
messes up with building with Clang Modules. (#6653, #4791) [@JohelEGP]
- Demo: Better showcase use of SetNextItemAllowOverlap(). (#6574, #6512, #3909, #517)
- Demo: Showcase a few more InputText() flags.
- Backends: Made all backends sources files support global IMGUI_DISABLE. (#6601)
- Backends: GLFW: Revert ignoring mouse data on GLFW_CURSOR_DISABLED as it can be used
differently. User may set ImGuiConfigFlags_NoMouse if desired. (#5625, #6609) [@scorpion-26]
- Backends: WebGPU: Update for changes in Dawn. (#6602, #6188) [@williamhCode]
- Examples: Vulkan: Creating minimal descriptor pools to fit only what is needed by
example. (#6642) [@SaschaWillem]

- 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.

- **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.)

### 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
```
Use the font atlas to pack them into a single texture. Read [docs/FONTS.md](https://github.com/ocornut/imgui/blob/master/docs/FONTS.md) for more details.

## Readme First
## Troubleshooting
**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.
**A vast majority of font and text related issues encountered comes from 4 things:**
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.
### (1) Invalid filename due to use of `\` or unexpected working directory.
**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");
```
![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.
![Fonts debugging](https://user-images.githubusercontent.com/8225057/135429892-0e41ef8d-33c5-4991-bcf6-f997a0bcfd6b.png)
#### 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.
![UTF-8 Encoding viewer](https://user-images.githubusercontent.com/8225057/166505963-8a0d7899-8ee8-4558-abb2-1ae523dc02f9.png)
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 looss.
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).

Some solutions:
## Loading Font Data from Memory
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`.
```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);
```

**For non-ASCII characters display, a common user issue is not passing correctly UTF-8 encoded strings.**

This is a convenient way to confirm that your encoding is correct.

```

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: `#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.

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. 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.

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).
- [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.
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!**

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."
