----------------------------------------------------------------------- -----------------------------------------------------------------------
Breaking Changes: Breaking Changes:
- IO: changed AddInputCharacter(unsigned short c) signature to AddInputCharacter(unsigned int c).
- Renamed SetNextTreeNodeOpen() to SetNextItemOpen(). Kept inline redirection function (will obsolete).
Other Changes: Other Changes:
- Columns: Fixed Separator from creating an extraneous draw command. (#125) - Columns: Fixed Separator from creating an extraneous draw command. (#125)
- Columns: Fixed Selectable with SpanAllColumns flag from creating an extraneous draw command. (#125) - Columns: Fixed Selectable with SpanAllColumns flag from creating an extraneous draw command. (#125)
- Separator: Revert 1.70 "Declare its thickness (1.0f) to the layout" change. It's not incorrect - Separator: Revert 1.70 "Declare its thickness (1.0f) to the layout" change. It's not incorrect
but it breaks existing some layout patterns. Will return back to it when we expose Separator flags. but it breaks existing some layout patterns. Will return back to it when we expose Separator flags.
- Fixed InputFloatX, SliderFloatX, DragFloatX functions erroneously reporting IsItemEdited() multiple
times when the text input doesn't match the formatted output value (e.g. input "1" shows "1.000").
It wasn't much of a problem because we typically use the return value instead of IsItemEdited() here.
- Fixed uses of IsItemDeactivated(), IsItemDeactivatedAfterEdit() on multi-components widgets and
after EndGroup(). (#2550, #1875)
- Scrollbar: Very minor bounding box adjustment to cope with various border size. - Scrollbar: Very minor bounding box adjustment to cope with various border size.
- ImFontAtlas: FreeType: Added RasterizerFlags::Monochrome flag to disable font anti-aliasing. (#2545)
Combine with RasterizerFlags::MonoHinting for best results.
- Examples/Backends: Don't filter characters under 0x10000 before calling io.AddInputCharacter(),
the filtering is done in io.AddInputCharacter() itself. This is in prevision for fuller Unicode
support. (#2538, #2541)
