@ -46,6 +46,16 @@ Breaking changes:
- new: io.PlatformSetImeDataFn(ImGuiContext* ctx, ImGuiViewport* viewport, ImGuiPlatformImeData* data);
It is expected that for a vast majority of users this is automatically set by core
library and/or platform backend so it won't have any effect.
- Item flag changes:
- Obsoleted PushButtonRepeat()/PopButtonRepeat() in favor of using new PushItemFlag()/PopItemFlag()
with ImGuiItemFlags_ButtonRepeat. Kept inline redirecting functions (will obsolete).
- Obsoleted PushTabStop()/PopTabStop() in favor of using new PushItemFlag()/PopItemFlag()
with ImGuiItemFlags_NoTabStop. Kept inline redirecting functions (will obsolete).
- Renamed ImGuiSelectableFlags_DontClosePopups to ImGuiSelectableFlags_NoAutoClosePopups for
consistency. Kept inline redirecting functions (will obsolete).
+ Internals: changed/inverted ImGuiItemFlags_SelectableDontClosePopup (default==false) to
ImGuiItemFlags_AutoClosePopups (default==true), same logic, only inverted behavior.
(#1379, #1468, #2200, #4936, #5216, #7302, #7573)
- Commented out obsolete ImGuiModFlags (renamed to ImGuiKeyChord in 1.89). (#4921, #456)
- Commented out obsolete ImGuiModFlags_XXX values (renamed to ImGuiMod_XXX in 1.89). (#4921, #456)
- ImGuiModFlags_Ctrl -> ImGuiMod_Ctrl, ImGuiModFlags_Shift -> ImGuiMod_Shift etc.
@ -58,12 +68,29 @@ Other changes:
- IO: added io.PlatformOpenInShellFn handler to open a link/folder/file in OS shell. (#7660)
Default to use ShellExecute() under Windows, and system("") under Mac/Linux/etc.
Added IMGUI_DISABLE_DEFAULT_SHELL_FUNCTIONS to disable default implementation.
- Added PushItemFlag()/PopItemFlags(), ImGuiItemFlags to modify shared item flags:
- Added ImGuiItemFlags_NoTabStop to disable tabbing through items.
- Added ImGuiItemFlags_NoNav to disable any navigation and focus of items. (#787)
- Added ImGuiItemFlags_NoNavDefaultFocus to disable item being default focus. (#787)
- Added ImGuiItemFlags_ButtonRepeat to enable repeat on any button-like behavior.
- Added ImGuiItemFlags_AutoClosePopups to disable menu items/selection auto closing parent popups.
Disabling this was previously possible for Selectable() via a direct flag but not for MenuItem().
(#1379, #1468, #2200, #4936, #5216, #7302, #7573)
- This was mostly all previously in imgui_internal.h.
- Clipper: added SeekCursorForItem() function. When using ImGuiListClipper::Begin(INT_MAX) you can
can use the clipper without knowing the amount of items beforehand. (#1311)
In this situation, call ImGuiListClipper::SeekCursorForItem(items_count) as the end of your iteration
loop to position the layout cursor correctly. This is done automatically if provided a count to Begin().
- Style: close button and collapse/window-menu button hover highlight made rectangular instead of round.
- Debug Tools: Added IMGUI_DEBUG_LOG(), ImGui::DebugLog() in public API. (#5855)
Debug log entries add a imgui frame counter prefix + are redirected to ShowDebugLogWindow() and
other configurable locations. Always call IMGUI_DEBUG_LOG() for maximum stripping in caller code.
- Debug Tools: Debug Log: Added "Configure Outputs.." button. (#5855)
- Demo: Reworked "Property Editor" demo in a manner that more ressemble the tree data and
struct description data that a real application would want to use.
- Backends: Win32: Fixed ImGuiMod_Super being mapped to VK_APPS instead of VK_LWIN||VK_RWIN.
(#7768, #4858, #2622) [@Aemony]
- Backends: SDL3: Update for API changes: SDL_GetClipboardText() string ownership change. (#7801)
- Backends: SDL3: Update for API changes: SDLK_x renames and SDLK_KP_x removals (#7761, #7762)
- Backends: SDL3: Update for API changes: SDL_GetProperty() change to SDL_GetPointerProperty(). (#7794) [@wermipls]
