documented (can only unreserve from the last reserve call). If you suspect you ever
|

used that feature before, #define IMGUI_DEBUG_PARANOID in imconfig.h to catch existing
|
||||
calls. [@ShironekoBen]
|
||||
- Limiting Columns()/BeginColumns() api to 64 columns with an assert. While the current code
|
||||
technically supports it, future code may not so we're putting the restriction ahead.
|
||||
- imgui_internal.h: changed ImRect() default constructor initializes all fields to 0.0f instead
|
||||
of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). If you used ImRect::Add() to create bounding boxes by
|
||||
adding multiple points into it, you may need to fix your initial value.

selection, those new api can fill a gap. [@ShironekoBen]
|
||||
- Backends: GLFW, SDL, Win32, OSX, Allegro: Added support for ImGuiMouseCursor_NotAllowed. [@rokups]
|
||||
- Backends: GLFW: Added support for the missing mouse cursors newly added in GLFW 3.4+. [@rokups]
|
||||
- Backends: SDL: Wayland: use SDL_GetMouseState (because there is no global mouse state available
|
||||
on Wayland). (#2800, #2802) [@NeroBurner]
|
||||
- Examples: Explicitly adding -DIMGUI_IMPL_OPENGL_LOADER_GL3W to Makefile to match linking
|

settings (otherwise if another loader such as Glew is accessible, the opengl3 backend might
|

automatically use it). [#2919, #2798]
