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.
  • 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() and AddConvexPolyFilled() 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 as privacy.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 calling SDL_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 call DefWindowProcW() instead of DefWindowProc() 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!

Note the release of Dear ImGui Bundle by @pthom
https://github.com/pthom/imgui_bundle
"Dear ImGui Bundle is a bundle for Dear ImGui, including various powerful libraries from its ecosystem. It enables to easily create ImGui applications in C++ and Python, under Windows, macOS, and Linux. It is aimed at application developers, researchers, and beginner developers who want to quickly get started."

Since 1.89 we semi-sneakily soft launched two new entire projects!

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."
