@ -39,6 +39,11 @@ Breaking Changes:
- Backends: SDL2: removed unnecessary SDL_Window* parameter from ImGui_ImplSDL2_NewFrame(). (#3244) [@funchal]
Kept inline redirection function (will obsolete).
- Backends: SDL2: backend needs to set 'SDL_SetHint(SDL_HINT_MOUSE_FOCUS_CLICKTHROUGH, "1")' in order to
receive mouse clicks events on window focus, otherwise SDL doesn't emit the event. (#3751, #4377, #2445)
This is unfortunately a global SDL setting, so enabling it _might_ have a side-effect on your application.
It is unlikely to make a difference, but if your app absolutely needs to ignore the initial on-focus click:
you can ignore SDL_MOUSEBUTTONDOWN that events coming right after a SDL_WINDOWEVENT_FOCUS_GAINED event).
- Commented out redirecting functions/enums names that were marked obsolete in 1.67 and 1.69 (March 2019):
- ImGui::GetOverlayDrawList() -> use ImGui::GetForegroundDrawList()
- ImFont::GlyphRangesBuilder -> use ImFontGlyphRangesBuilder
