dear imgui CHANGELOG This document holds the user-facing changelog that we also use in release notes. We generally fold multiple commits pertaining to the same topic as a single entry. Changes to backends are also included within the individual .cpp files of each backend. FAQ https://www.dearimgui.com/faq/ RELEASE NOTES: https://github.com/ocornut/imgui/releases WIKI https://github.com/ocornut/imgui/wiki GETTING STARTED https://github.com/ocornut/imgui/wiki/Getting-Started GLOSSARY https://github.com/ocornut/imgui/wiki/Glossary ISSUES & SUPPORT https://github.com/ocornut/imgui/issues 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. 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. - 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. - 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 1.92.9 WIP (In Progress) ----------------------------------------------------------------------- Breaking Changes: - TreeNode: commented out legacy name `ImGuiTreeNodeFlags_SpanTextWidth` which was obsoleted in 1.90.7 (May 2024). Use `ImGuiTreeNodeFlags_SpanLabelWidth`. - ColorEdit: obsoleted SetColorEditOptions() function added in 1.51 (June 2017) in of directly poking to io.ConfigColorEditFlags. More consistent and easier to discover. Other Changes: - Windows: - Clicking on a window's empty-space to move/focus a window checks for lack of mouse button ownership. This gives an additional opportunity for user code to bypass it without using a clickable item. (#9382) - Clicking on a window's empty-space to move/focus a window checks for lack of queued focus request. (#9382) - Fixed double-click collapse toggle not owning the mouse button. If a `SetNextWindowPos()` with pivot was queued in the same frame, the second click could trigger another item in the same window. (#9439) [@Cleroth] - InputText: - Added `style.InputTextCursorSize` to configure cursor/caret thickness. (#7031, #9409) This is automatically scaled by `style.ScaleAllSizes()`. - Tables: - Redesigned/rewrote code to reconcile columns and settings on topology changes. (#9108) - When a column label is passed to TableSetupColumn(), the underlying identifier is used to match live columns data and .ini settings data when changing. This makes it possible to add/remove columns from a table without losing neither live data neither .ini settings data. - PS: Note that this is distinct from toggling column visibility or reordering columns, which was always possible. The new matching makes it easier to create tables that are entirely customized by user or code, without losing state. - Columns without identifiers or with duplicate identifiers are matched sequentially, matching old behavior. - Column ID are stored in .ini file. - Code is being tested both for live topology changes and for loading .ini data with mismatched topology. - Context Menu: added a "Reset" sub-menu with a "Reset Visibility" option. (which is greyed out when using default settings) - Headers: fixed label being clipped early to reserve space for a sort marker even when no sort marker is displayed. Auto-fitting a column still accounts for the possible marker, so that sorting after an auto-fit doesn't clip the label. - Multi-Select - Reworked ImGuiMultiSelectFlags_NoAutoSelect as it carried side-effects that were hardcoded/designed to use multi-selection on checkboxes. (#9391) Specifically removed those undocumented behaviors from _NoAutoSelect: - Clicking a selected/checked item always unselect/uncheck. - Shift+Click inverts targets value and copy to range. - Shift+Keyboard copy selection source value to range. Those behaviors are still happening on checkboxes used within multi-selection. - Fonts: - Added `IMGUI_DISABLE_DEFAULT_FONT_BITMAP`/`IMGUI_DISABLE_DEFAULT_FONT_VECTOR` to disable embedding either fonts separately. (#9407) - Tweak `CalcTextSize()` awkward width rounding/ceiling code to reduce floating-point imprecisions altering the result by 1 even at relatively small width. (#791) - Better document the fact that ImFontAtlas::Clear()/ClearFonts() functions are unlikely to be useful nowadays. Better recover to an edge case of mistakenly calling ClearFonts() during rendering. - Fixed an issue where passing a manually created ImFontAtlas to CreateContext() would incorrectly destroy it in DestroyContext() when ref-count gets back to zero. (#9426) - Destroying an ImGui context using a ImFontAtlas checks that the later has no references. - Nav: - Fixed context menu activation with gamepad erroneously testing for _NavEnableKeyboard instead of _NavEnableGamepad. (#9454, #8803, #9270) [@Clownacy] - TreeNode: - Fixed nav cursor rendering with rounding even though tree nodes don't have it. (#7589) - Inputs: - Added GetItemClickedCountWithSingleClickDelay() helper for easy disambiguation between single-click and double-click for actions that needs single-click to do something other than selection. (#8337) - Returns 1 on single-click but delayed by io.MouseSingleClickDelay. - Returns 2 on double-click, and 2+ on subsequent repeated cicks. - Added io.MouseSingleClickDelay to configure default delayed single click delay when using GetItemClickedCountWithSingleClickDelay() or IsMouseReleasedWithDelay(). (#8337) Note that io.MouseSingleClickDelay is always > io.MouseDoubleClickTime. - ColorEdit: - Added `io.ConfigColorEditFlags` to read/modify current color edit/picker settings. - ColorPicker: added `ImGuiColorEditFlags_PickerNoRotate` to disable rotation of the S/V triangle when in `ImGuiColorEditFlags_PickerHueWheel` mode. (#9337) [@SeanTheBuilder1] Likely best passed to `style.ColorEditFlags` to setup globally and once. - ColorButton: small rendering tweak/optimization for the alpha checkerboard. - Style: - Added style.MenuItemRounding, ImGuiStyleVar_MenuItemRounding. (#7589, #9375, #9453) - Added style.SelectableRounding, ImGuiStyleVar_SelectableRounding. (#7589, #9375, #9453) The use of this is discouraged because it can easily create problems rendering e.g. contiguous selection. - Scale the NavCursor border thickness when using large values with `ScallAllSizes()`. - Settings: - Windows/Tables settings entries can now record the last used date in YYYYMMDD format, allowing tools to run to e.g. delete entries that haven't been used in X months. (#9460) - Added bool io.ConfigIniSettingsSaveLastUsedDate to disable saving that info. (#9460) - Added int io.ConfigIniSettingsAutoDiscardMonths to enable a mode where unused settings are automatically discard after xx months. (#9460) - Added a trimming tool under Metrics->Settings, along with a yet-unexposed function. - The current system date is fed through ImGuiPlatformIO::Platform_SessionDate, which is automatically set by a call to time() done during context creation. (#9460) - Added IMGUI_DISABLE_TIME_FUNCTIONS to disable setting platform_io.Platform_SessionDate. A custom backend may still set it manually. (#9460) - DrawList: - Minor optimization to `AddLine()`, `AddLineH()`, `AddLineV()` functions. (#4091) - Added `ImDrawListFlags_TextNoPixelSnap` to disable snapping of AddText() coordinates for a given scope. (#3437, #9417, #2291) - Demo: - Extract 'Widgets->Tree Nodes->Selectable Nodes' out of the 'Advanced' demo for clarity (manual reimplementation of basic selection). - Misc: - Added IM_DEBUG_BREAK() handler for GCC+AArch64/ARM64. [@tom-seddon] - Backends: - Metal4: - Added new Metal 4 backend (forked from Metal 3 backend). (#9458, #9451) [@AmelieHeinrich] Note that Metal-cpp is not yet supported. - OpenGL3: - GLSL version detection assume GLSL 410 when GL context is 4.1. Fixes an issue running on macOS with Wine. [#9427, #6577) [@perminovVS] - Expose selected render state in ImGui_ImplOpenGL3_RenderState, allowing to dynamically select between use of glBindSampler() and glTexParameter(). (#9378) - Win32: - Uses `SetProcessDpiAwarenessContext()` instead of `SetThreadDpiAwarenessContext()` when available, fixing OpenGL DPI scaling issues as e.g. NVIDIA drivers tends to spawn multiple-thread to manage OpenGL. (#9403) - Examples: - Android: update to AGP 9.2.0 to support Gradle 9.6.0. - OpenGL3+GLFW/SDL2/SDL3: allow Wine compatibility by passing empty GLSL version string to ImGui_ImplOpenGL3_Init() to let backend decide of a GLSL version based on actual GL version obtained. (#9427, #6577) [@perminovVS] - OpenGL3+Win32: rework context creation to allow Wine compatibility. (#9427, #6577) [@perminovVS] - SDL2/SDL3: use `SDL_GetWindowSizeInPixels()` to create frame-buffers. Fixes issues with non-fractional framebuffer size on Wayland. (#8761, #9124) [@billtran1632001] - SDL3+Metal4: added new example. (#9458, #9451) [@AmelieHeinrich] ----------------------------------------------------------------------- VERSION 1.92.8 (Released 2026-05-12) ----------------------------------------------------------------------- Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.92.8 Breaking Changes: - DrawList: swapped the last two arguments of `AddRect()`, `AddPolyline()`, `PathStroke()`. - Before: `void ImDrawList::AddRect(ImVec2 p_min, ImVec2 p_max, ImU32 col, float rounding = 0.0f, ImDrawFlags flags = 0, float thickness = 1.0f);` - After: `void ImDrawList::AddRect(ImVec2 p_min, ImVec2 p_max, ImU32 col, float rounding = 0.0f, float thickness = 1.0f, ImDrawFlags flags = 0);` - Before: `void ImDrawList::AddPolyline(const ImVec2* points, int num_points, ImU32 col, ImDrawFlags flags, float thickness);` - After: `void ImDrawList::AddPolyline(const ImVec2* points, int num_points, ImU32 col, float thickness, ImDrawFlags flags = 0);` - Before: `void ImDrawList::PathStroke(ImU32 col, ImDrawFlags flags = 0, float thickness = 1.0f);` - After: `void ImDrawList::PathStroke(ImU32 col, float thickness = 1.0f, ImDrawFlags flags = 0);` Added inline redirection functions when IMGUI_DISABLE_OBSOLETE_FUNCTIONS is off. Marked the old functions are =delete when IMGUI_DISABLE_OBSOLETE_FUNCTIONS is on, to allow for better type-checking. Effectively the typical call site is changing from: - Before: `window->DrawList->AddRect(p_min, p_max, color, rounding, ImDrawFlags_None, border_size);` - After: `window->DrawList->AddRect(p_min, p_max, color, rounding, border_size);` Notes: - Users of C++ and other languages with type-checking will be notified at compile-time of any mistakes. - Users of high-level bindings or languages with no type-checking will be notified at runtime via an assert for invalid flags value. If you are a binding maintainer consider doing something to facilitate transition or error detection. - This is perhaps the worst breaking change in our history :( but it makes ImDrawList function signatures consistent. As we are aiming to add flags and features to variety of ImDrawList functions, that consistency becomes more important. The new order is also more convenient as `flags` are less frequently used than `thickness` in real code. - As a general policy in Dear ImGui, all our flags default to 0 so ImDrawFlags_None was likely written 0 in some call sites. - Consider adding `#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS` in your imconfig.h, even temporarily, to clean up legacy code. - Reminder: you do NOT need to specify `ImDrawFlags_RoundCornersAll` for rounding, it is already the default! - DrawList: obsoleted `ImDrawCallback_ResetRenderState` in favor of using `ImGui::GetPlatformIO().DrawCallback_ResetRenderState`, which is part of our new standard draw callbacks. (#9378) Redirecting the earlier value into the later one when set, so both old and new code should work. - DrawList: changed value of `ImDrawFlags_Closed`. It was previously advertised as "always == 1" when introduced in 1.82 (2021/02), in order to facilitate backward compatibility with the legacy `bool closed` flag. This guarantee has been removed. The bit is reserved, and `AddPolyline()`, `PathStroke()` will assert when it is used. - Backends: - Vulkan: redesigned to use separate ImageView + Sampler instead of Combined Image Sampler. (#914) This change allows us to facilitate changing samplers, in line with other backends. [@yaz0r, @ocornut] - When creating your own descriptor pool (instead of letting backend creates its own): - Before: need at least `IMGUI_IMPL_VULKAN_MINIMUM_IMAGE_SAMPLER_POOL_SIZE` descriptors of type `VK_DESCRIPTOR_TYPE_COMBINED_IMAGE_SAMPLER`. - After: need at least `IMGUI_IMPL_VULKAN_MINIMUM_SAMPLED_IMAGE_POOL_SIZE` descriptors of type `VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE`. + `IMGUI_IMPL_VULKAN_MINIMUM_SAMPLER_POOL_SIZE` descriptors of type `VK_DESCRIPTOR_TYPE_SAMPLER`. - When registering custom textures: changed ImGui_ImplVulkan_AddTexture() signature to remove Sampler. - Before: `ImGui_ImplVulkan_AddTexture(VkSampler, VkImageView, VkImageLayout)` - After: `ImGui_ImplVulkan_AddTexture(VkImageView, VkImageLayout)` - Kept inline redirection function that ignores the sampler (will obsolete). - DirectX10, DirectX11, SDLGPU3, Vulkan: removed samplers from `ImGui_ImplXXXX_RenderState`. Prefer to use backend-agnostic DrawCallback_SetSamplerLinear which works everywhere! (#9378) If there is a legit need/request for them or any render state we can always add them back. - OpenGL3: the new sampler support system prioritize using glBindSampler() when available, which would override glTexParameter() settings you may have set on custom textures. (#9378) Other Changes: - DrawList: - Added room in `ImGuiPlatformIO` for standard backend-agnostic draw callbacks. Those callbacks are setup/provided by the backend and available in most of our standard backends. They allow backend-agnostic code from e.g. switching to a Nearest/Point sampler without messing with custom Renderer-specific callbacks. platform_io.DrawCallback_ResetRenderState; // Request to reset the graphics/render state. platform_io.DrawCallback_SetSamplerLinear; // Request to set current texture sampling to Linear platform_io.DrawCallback_SetSamplerNearest; // Request to set current texture sampling to Nearest/Point Note that some backends might not support all callbacks. (#9378, #9371, #3590, #8926, #2973, #7485, #7468, #6969, #5118, #7616, #9173, #8322, #7230, #5999, #6452, #5156, #7342, #7592, #7511) - Made `AddCallback()` user data default to Null for convenience. - Added `AddLineH()`, `AddLineV()` helpers to draw horizontal and vertical lines. [@memononen] The new functions are more optimal and will be part of a larger effort in 1.93 to fix inconsistencies and improve the DrawList API. In the current API, `AddLine()` adds a "magic" +0.5f offset and then center the line, whereas AddLineH()/AddLineV() use the right side of the line to expand. For thickness=1.0f lines this is equivalent: `AddLine({10,3}, {20,3}, ...)` --> `AddLineH(x1=10, x2=20, y=3, ...)`. `AddLine({3,10}, {3,20}, ...)` --> `AddLineV(x=3, y1=10, y2=20, ...)`. For larger integer thickness, AddLine() will center but may be blurry, AddLineH()/AddLineV() will expand "inside" (to the right side) and will always be sharp. A subsequent release will expand on those concepts and add new options. - InputText: - InputTextMultiline: fixed an issue processing deactivation logic when an active multi-line edit is clipped due to being out of view. - Fixed a crash when toggling ReadOnly while active. (#9354) - `CharFilter` callback event sets CursorPos/SelectionStart/SelectionEnd. (#816) - Tables: - Fixed issues reporting ideal size to parent window/container: (#9352, #7651) - When both scrollbars are visible but only one of ScrollX/ScrollY was explicitly requested. - When vertical scrollbar was not at the top, the computation was often incorrect. - Windows: - Fixed a single-axis auto-resizing feedback loop issue with nested containers and varying scrollbar visibility. (#9352) - Detect and report error when calling End() instead of EndPopup() on a popup. (#9351) - Child windows with only `ImGuiChildFlags_AutoResizeY` flag keep using the proportional default `ItemWidth`. (#9355) - Using mouse wheel to scroll takes and keeps ownership of the corresponding keys (e.g. `ImGuiKey_MouseWheelY`) while a wheeling window is locked. (#2604, #3795) - InputInt, InputFloat, InputScalar: - Reinstated `ImGuiInputTextFlags_EnterReturnsTrue` support which was removed in 1.91.4. (#8665, #9299, #8065, #3946, #6284, #9117) - Fixed the fact that it didn't return true when validating same value. - Fixed losing value when tabbing out or losing focus. - Made it that pressing +/- step buttons also return true, which is in line with 1.91.4 behavior. - In a majority of cases you should use `IsItemDeactivatedAfterEdit()` instead, but it still has a few edge cases flaws (to be addressed soon). - Allow passing a format string that does not display the scalar value. Parsing input with default format for the type. (#9385) [@FireFox2000000] - Multi-Select: - Fixed an issue using Multi-Select within a Table causing column width measurement to be invalid when trailing column contents is not submitted in the last row. (#9341, #8250) - Fixed an issue using Multi-Select within a Table with the right-most column visible, which could lead to an extra vertical offset in the Header row. (#8250) - Multi-Select + Box-Select: - Fixed an issue using `ImGuiMultiSelectFlags_BoxSelect1d` mode while scrolling. Notably, using mouse wheel while holding a box-selection could lead items close to windows edges from not being correctly unselected. (#7994, #8250, #7821, #7850, #7970) - Improved dirty/unclip rectangle logic for `ImGuiMultiSelectFlags_BoxSelect2d`. - Fixed an issue using `ImGuiMultiSelectFlags_BoxSelect2d` mode, where items out of view wouldn't be properly selected while scrolling while mouse cursor is hovering outside of selection scope. (#7994, #1861, #6518) - Fixed an issue where items out of horizontal view would sometimes lead to incorrect merging of sequential selection requests while also scrolling fast enough to overlap multiple rows during a frame. (#7994, #1861, #6518) - Fixed an issue using `ImGuiMultiSelectFlags_BoxSelect2d` mode in a Table while relying on the `TableNextColumn()` return value to perform coarse clipping. (#7994) - Disabled merging consecutive selection requests as we have no reliable way of detecting if user has submitted all consecutive items without clipping gaps, and `ImGuiSelectionUserData` is technically opaque storage. (#7994, #1861) (we will probably bring this back as a minor optimization if we have a way to for user to tell us `ImGuiSelectionUserData` are indices) - Fixes for using across nested child windows. (#8364) - Box-Select + Clipper: fixed an issue selecting items while scrolling while a clipper active. (#7994, #8250, #7821, #7850, #7970) - Box-Select + Tables: fixed an issue using box-selection in a tables with items straying out of columns boundaries. (#7994, #2221) - Box-Select + Tables: fixed an issue when calling `BeginMultiSelect()` in a table before layout has been locked (first row or headers row submitted). (#8250) - Menus: - BeginMenu()/MenuItem(): fixed accidental triggering of child menu items when opening a menu inside a small host window forcing the child menu window to be repositioned under the mouse cursor. (#8233, #9394) Done by reworking `BeginMenu()`/`MenuItem()`: they previously avoiding taking ActiveID + key/click ownership (in order to allow releasing button on another item). Now they take them and release them once the mouse is moved outside item boundaries. - Inputs: - SetItemKeyOwner(): return true if ownership has been requested, which typically needs to to checked for gating further tests. This is important as the function may fail. (#456, #2637, #2620, #2891, #3370, #3724, #4828, #5108, #5242, #5641) - SetItemKeyOwner(): does not set ownership is key is already taken. Effectively this makes using `SetItemKeyOwner(ImGuiKey_MouseWheelY)` over an item work as expected while not having item react if a scroll wheel is actively in progress. May be subject to further redesign, e.g. conditional flags. Feedback welcome! - Style: - Checkbox: added `ImGuiCol_CheckboxSelectedBg` to change or accentuate the background color of checked/mixed checkboxes. (#9392) - Added `ImGuiStyleVar_DragDropTargetRounding`. (#9056) - Fixed vertical scrollbar top coordinates when using thick borders on windows with no title bar and no menu bar. (#9366) - Fonts: - imgui_freetype: add FreeType headers & compiled version in 'About Dear ImGui' details. - Assert when using MergeMode with an explicit size over a target font with an implicit size, as scale factor are likely erroneous. (#9361) - Clipper: - Improved error reporting when misusing the clipper inside a table (prioritize reporting the common clipper error over a table sanity check assert). (#9350) - Tweaked assert triggering when first item height measurement fails, and made it a better recoverable error. (#9350) - Misc: - Minor optimization: reduce redundant label scanning in common widgets. - Added missing Test Engine hooks for `PlotLines()`, `PlotHistogram()`, `VSliderXXX()` and `TableHeader()` functions. - Demo: - Added simple demo for a scrollable/zoomable image viewer with a grid. Available in `Examples->Image Viewer` and `Widgets->Images`. - Backends: - Added support for new standardized draw callbacks in most backends: (#9378) - Allegro5: Reset n/a n/a - DX9: Reset SetSamplerLinear SetSamplerNearest - DX10: Reset SetSamplerLinear SetSamplerNearest - DX11: Reset SetSamplerLinear SetSamplerNearest - DX12: Reset SetSamplerLinear SetSamplerNearest - Metal: Reset SetSamplerLinear SetSamplerNearest - OpenGL2: Reset SetSamplerLinear SetSamplerNearest - OpenGL3+: Reset SetSamplerLinear SetSamplerNearest - SDLGPU3: Reset SetSamplerLinear SetSamplerNearest - SDLRenderer2: Reset n/a n/a - SDLRenderer3: Reset SetSamplerLinear SetSamplerNearest - Vulkan: Reset SetSamplerLinear SetSamplerNearest - WebGPU: Reset SetSamplerLinear SetSamplerNearest (Vulkan backend by @yaz0r, Metal by @ssh4net, others by @ocornut) - GLFW: added a Win32-specific implementation of `ImGui_ImplGlfw_GetContentScaleXXXX` functions for legacy GLFW 3.2. (#9003) - Metal: avoid redundant vertex buffer bind in `SetupRenderState()`, which leads to validation issue. (#9343) [@Hunam6] - Metal: use a dedicated `bufferCacheLock` to avoid crashing when `bufferCache` is replaced by a new object while being used for `@synchronize()`. (#9367) [@andygrundman] - SDL2: made `ImGui_ImplSDL2_GetContentScaleForWindow()`/`ImGui_ImplSDL2_GetContentScaleForDisplay()` helpers return a minimum of 1.0f, as some Linux setup seems to report <1.0f value and this breaks scaling border size. (#9369) - WebGPU: rework choice/detection of using WGSL/SPIR-V shader on WGVK. (#9316, #9246, #9257, #9387) - Examples: - Update VS toolset in all .vcxproj from VS2015 (v140) to VS2017 (v141). The later is the first that supports vcpkg. Onward we will likely stop testing building the library with VS2015. - GLFW+Vulkan, SDL2+Vulkan, SDL3+Vulkan, Win32+Vulkan: reworked to create a descriptor pool with: - `IMGUI_IMPL_VULKAN_MINIMUM_SAMPLED_IMAGE_POOL_SIZE` descriptors of type `VK_DESCRIPTOR_TYPE_SAMPLED_IMAGE`. - `IMGUI_IMPL_VULKAN_MINIMUM_SAMPLER_POOL_SIZE` descriptors of type `VK_DESCRIPTOR_TYPE_SAMPLER`. ----------------------------------------------------------------------- VERSION 1.92.7 (Released 2026-04-02) ----------------------------------------------------------------------- Decorated log and release notes: https://github.com/ocornut/imgui/releases/tag/v1.92.7 Breaking Changes: - Separator: fixed a legacy quirk where `Separator()` was submitting a zero-height item for layout purpose, even though it draws a 1-pixel separator. The fix could affect code e.g. computing height from multiple widgets in order to allocate vertical space for a footer or multi-line status bar. (#2657, #9263) The "Console" example had such a bug: float footer_height = style.ItemSpacing.y + ImGui::GetFrameHeightWithSpacing(); BeginChild("ScrollingRegion", { 0, -footer_height }); Should be: float footer_height = style.ItemSpacing.y + style.SeparatorSize + ImGui::GetFrameHeightWithSpacing(); BeginChild("ScrollingRegion", { 0, -footer_height }); When such idiom was used and assuming zero-height Separator, it is likely that in 1.92.7 the resulting window will have unexpected 1 pixel scrolling range. - Multi-Select: renamed `ImGuiMultiSelectFlags_SelectOnClick` to `ImGuiMultiSelectFlags_SelectOnAuto`. Kept inline redirection enum (will obsolete). - Combo(), ListBox(): commented out legacy signatures which were obsoleted in 1.90 (Nov 2023), when the getter callback type was changed from: bool (*getter)(void* user_data, int idx, const char** out_text) To: const char* (*getter)(void* user_data, int idx) Other Changes: - TreeNode: - Moved `TreeNodeGetOpen()` helper to public API. I was hesitant to make this public because I intend to provide a more generic and feature-full version, but in the meanwhile this will do. (#3823, #9251, #7553, #6754, #5423, #2958, #2079, #1947, #1131, #722) - In 'Demo->Property Editor' demonstrate a way to perform tree clipping by fast-forwarding through non-visible chunks. (#3823, #9251, #6990, #6042) Using SetNextItemStorageID() + TreeNodeGetOpen() makes this notably easier than it was prior to 1.91. - InputText: - Shift+Enter in multi-line editor always adds a new line, regardless of `ImGuiInputTextFlags_CtrlEnterForNewLine` being set or not. (#9239) - Reworked `io.ConfigInputTextEnterKeepActive` mode so that pressing Enter will deactivate/reactivate the item in order for e.g. `IsItemDeactivatedAfterEdit()` signals to be emitted the same way regardless of that setting. (#9001, #9115) - Fixed a glitch when using `ImGuiInputTextFlags_ElideLeft` where the local x offset would be incorrect during the deactivation frame. (#9298) - Fixed a crash introduced in 1.92.6 when handling `ImGuiInputTextFlags_CallbackResize` in certain situations. (#9174) - Fixed selection highlight Y1 offset being very slightly off (since 1.92.3). (#9311) [@v-ein] - InputTextMultiline: fixed an issue introduced in 1.92.3 where line count calculated for vertical scrollbar range would be +1 when the widget is inactive, word-wrap is disabled and the text buffer ends with '\n'. Fixed a similar issue related to clipping large amount of text. - InputTextMultiline: avoid going through reactivation code and fixed losing revert value when activating scrollbar. - InputTextMultiline: fixed an issue where edit buffer wouldn't be reapplied to back buffer on the `IsItemDeactivatedAfterEdit()` frame. This could create issues when using the idiom of not applying edits before `IsItemDeactivatedAfterEdit()`. (#9308, #8915, #8273) - Tables: - Allow reordering columns by dragging them in the context menu. (#9312) - Context menu now presents columns in display order. (#9312) - Fixed and clarified the behavior of using `TableSetupScrollFreeze()` with columns>1, and where some of the columns within that range were Hidable. - Before: `TableSetupScrollFreeze(N, 0)`: include the N left-most visible columns as part of the scroll freeze. So if you intentionally hide columns
