- Many other tweaks/fixes.
Changes
This is a followup to v1.89, v1.89.1 and v1.89.2. We are trying to make more frequent releases. Because: some people are relying on tagging and auto-generated bindings for other languages. And: it sets a beat and may encourage teams to update more frequently.
Breaking Changes:
- Backends+Examples: SDL2: renamed all unnumbered references to "sdl" to "sdl2". This is in prevision for the future release of SDL3 and its associated backend. (#6146)
-
imgui_impl_sdl.cpp
->imgui_impl_sdl2.cpp
-
imgui_impl_sdl.h
->imgui_impl_sdl2.h
-
example_sdl_xxxx/
->example_sdl2_xxxx/
(folders and projects)
-
Other Changes:
- SeparatorText(): Added
SeparatorText()
widget. (#1643) [@phed, @ocornut]- Added to style:
float SeparatorTextBorderSize
. - Added to style:
ImVec2 SeparatorTextAlign
,ImVec2 SeparatorTextPadding
.
- Added to style:
- Tables: Raised max Columns count from 64 to 512. The previous limit was due to using 64-bit integers but we moved to bits-array and tweaked the system enough to ensure no performance loss. (#6094, #5305, #4876, #3572)
- Tables: Solved an ID conflict issue with multiple-instances of a same table, due to how unique table instance id was generated. (#6140) [@ocornut, @rodrigorc]
- Inputs, Scrolling: Made horizontal scroll wheel and horizontal scroll direction consistent across backends/os. (#4019, #6096, #1463) [@PathogenDavid, @ocornut, @rokups]
- Clarified that 'wheel_y > 0.0f' scrolls Up, 'wheel_y > 0.0f' scrolls Down.
- Clarified that 'wheel_x > 0.0f' scrolls Left, 'wheel_x > 0.0f' scrolls Right.
- Backends: Fixed horizontal scroll direction for Win32 and SDL backends. (#4019)
- Shift+WheelY support on non-OSX machines was already correct. (#2424, #1463) (whereas on OSX machines Shift+WheelY turns into WheelX at the OS level).
- If you use a custom backend, you should verify horizontal wheel direction.
- Axises are flipped by OSX for mouse & touch-pad when 'Natural Scrolling' is on.
- Axises are flipped by Windows for touch-pad when 'Settings->Touchpad->Down motion scrolls up' is on.
- You can use
Demo->Tools->Debug Log->IO
to visualize values submitted to Dear ImGui.
- Known issues remaining with Emscripten:
- The magnitude of wheeling values on Emscripten was improved but isn't perfect. (#6096)
- When running the Emscripten app on a Mac with a mouse, SHIFT+WheelY doesn't turn into WheelX. This is because we don't know that we are running on Mac and apply our own Shift+swapping on top of OSX' own swapping, so wheel axises are swapped twice. Emscripten apps may need to find a way to detect this and set
io.ConfigMacOSXBehaviors
manually (if you know a way let us know!), or offer the "OSX-style behavior" option to their user.
- Window: Avoid rendering shapes for hidden resize grips.
- Text: Fixed layouting of wrapped-text block skipping successive empty lines, regression from the fix in 1.89.2. (#5720, #5919)
- Text: Fixed clipping of single-character "..." ellipsis (U+2026 or U+0085) when font is scaled. Scaling wasn't taken into account, leading to ellipsis character straying slightly out of its expected boundaries. (#2775)
- Text: Tweaked rendering of three-dots "..." ellipsis variant. (#2775, #4269)
- InputText: Added support for Ctrl+Delete to delete up to end-of-word. (Not adding Super+Delete to delete to up to end-of-line on OSX, as OSX doesn't have it) (#6067) [@ajweeks]
- InputText: On OSX, inhibit usage of Alt key to toggle menu when active (used for work skip).
- Menus: Fixed layout of
MenuItem()
/BeginMenu()
when label contains a '\n'. (#6116) [@imkcy9] - ColorEdit, ColorPicker: Fixed hue/saturation preservation logic from interfering with the displayed value (but not stored value) of others widgets instances. (#6155)
- PlotHistogram, PlotLines: Passing negative sizes honor alignment like other widgets.
- Combo: Allow
SetNextWindowSize()
to alter combo popup size. (#6130) - Fonts: Assert that in each
GlyphRanges[]
pairs first is <= second. - ImDrawList: Added missing early-out in
AddPolyline()
andAddConvexPolyFilled()
when color alpha is zero. - Misc: Most text functions treat
"%s"
as a shortcut to no-formatting. (#3466) - Misc: Tolerate zero delta-time under Emscripten as backends are imprecise in their values for
io.DeltaTime
, and browser features such asprivacy.resistFingerprinting=true
can exacerbate that. (#6114, #3644) - Backends: OSX: Fixed scroll/wheel scaling for devices emitting events with
hasPreciseScrollingDeltas==false
(e.g. non-Apple mices). - Backends: Win32: flipping
WM_MOUSEHWHEEL
horizontal value to match other backends and offer consistent horizontal scrolling direction. (#4019) - Backends: SDL2: flipping
SDL_MOUSEWHEEL
horizontal value to match other backends and offer consistent horizontal scrolling direction. (#4019) - Backends: SDL2: Removed
SDL_MOUSEWHEEL
value clamping. (#4019, #6096, #6081) - Backends: SDL2: Added support for SDL 2.0.18+
preciseX
/preciseY
mouse wheel data for smooth scrolling as reported by SDL. (#4019, #6096) - Backends: SDL2: Avoid calling
SDL_SetCursor()
when cursor has not changed, as the function is surprisingly costly on Mac with latest SDL (already fixed in SDL latest trunk). (#6113) - Backends: SDL2: Implement IME handler to call
SDL_SetTextInputRect()
/SDL_StartTextInput()
. It will only works with SDL 2.0.18+ if your code calls 'SDL_SetHint(SDL_HINT_IME_SHOW_UI, "1")' prior to callingSDL_CreateWindow()
. Updated all examples accordingly. (#6071, #1953) - Backends: SDL3: Added experimental
imgui_impl_sdl3.cpp
backend. SDL 3.0.0 has not yet been released, so it is possible that its specs/api will change before release. This backend is provided as a convenience for early adopters etc. We don't recommend switching to SDL3 before it is released. (#6146) [@dovker, @ocornut] - Backends: GLFW: Registering custom low-level mouse wheel handler to get more accurate scrolling impulses on Emscripten. (#4019, #6096) [@ocornut, @wolfpld, @tolopolarity]
- Backends: GLFW: Added
ImGui_ImplGlfw_SetCallbacksChainForAllWindows()
to instruct backend to chain callbacks even for secondary viewports/windows. User callbacks may need to test the 'window' parameter. (#6142) - Backends: OpenGL3: Fixed GL loader compatibility with 2.x profiles. (#6154, #4445, #3530) [@grauw]
- Backends: WebGPU: Fixed building for latest WebGPU specs (remove implicit layout generation). (#6117, #4116, #3632) [@tonygrue, @bfierz]
- Examples: refactored SDL2+GL and GLFW+GL examples to compile with Emscripten. (#2492, #2494, #3699, #3705) [@ocornut, @nicolasnoble] The dedicated example_emscripten_opengl3/ has been removed.
- Examples: Added SDL3+GL experimental example. (#6146)
- Examples: Win32: Fixed examples using
RegisterClassW()
since 1.89 to also callDefWindowProcW()
instead ofDefWindowProc()
so that title text are correctly converted when application is compiled without/DUNICODE
. (#5725, #5961, #5975) [@markreidvfx] - Examples: SDL2+SDL_Renderer: Added call to
SDL_RenderSetScale()
to fix display on a Retina display (albeit lower-res as our other unmodified examples). (#6121, #6065, #5931).
Changes from 1.89.2 to 1.89.3 related to the docking branch (multi-viewport and docking features) include:
- Backends: GLFW: Handle unsupported glfwGetVideoMode() for Emscripten. (#6096)
New exciting projects!

Application for controlling a custom GoTo-AltAz-Mount for my telescope by @PlanEl180223 "Here is a preview of what the user interface of my application looks like. It uses an OpenGL backend, and C++. Don't get distracted by the weird descriptions on the individual targets, I am still parsing them wrong."
SpriteMancer by @CodeManu https://spritemancer.com
LogToGraph by @aiekick "At job, I needed a tool for display Numerical Signal based logs to graph curve, for easy analyze. The tool is called LogToGraph So generic, since the parsing of a log file is done by a lua script. so easy modifable by a user. In more than Dear ImGui, Thanks to ImPlot for his incredible graph possibilites."
