|
|||
- InputText: On Mac OS X, filter out characters when the Cmd modifier is held. (#1747) [@sivu]
|
||||
- InputText: On Mac OS X, support Cmd+Shift+Z for Redo. Cmd+Y is also supported as major apps seems to default to support both. (#1765) [@lfnoise]
|
||||
- Style: Changed default style.DisplaySafeAreaPadding values from (4,4) to (3,3) so it is smaller than FramePadding and has no effect on main menu bar on a computer. (#1439)
|
||||
- Misc: Added IMGUI_CHECKVERSION() macro to compare version string and data structure sizes in order to catch issues with mismatching compilation unit settings. (#1695, #1769)
|
||||
- Demo: Fixed Overlay: Added a context menu item to enable freely moving the window.
|
||||
- Examples: Calling IMGUI_CHECKVERSION() in the main.cpp of every example application.
|
||||
- Examples: Allegro 5: Added support for 32-bit indices setup via defining ImDrawIdx, to avoid an unnecessary conversion (Allegro 5 doesn't support 16-bit indices).
|
||||
- Examples: Allegro 5: Renamed bindings from imgui_impl_a5.cpp to imgui_impl_allegro5.cpp.
|
||||
- Various minor fixes, tweaks, refactoring, comments.
