@ -105,6 +105,9 @@ Other changes:
Breaking Changes:
- Removed unncessary ID (first arg) of ImFontAtlas::AddCustomRectRegular() function. Please
note that this is a Beta api and will likely be reworked to support multi-monitor multi-DPI.
Other Changes:
- TreeNode: Fixed bug where BeginDragDropSource() failed when the _OpenOnDoubleClick flag is
@ -112,7 +115,18 @@ Other Changes:
flag was also set, and _OpenOnArrow is frequently set along with _OpenOnDoubleClick).
- TreeNode: Fixed bug where dragging a payload over a TreeNode() with either _OpenOnDoubleClick
or _OpenOnArrow would open the node. (#143)
- Style: Added style.TabMinWidthForUnselectedCloseButton settings.
Set to 0.0f (default) to always make a close button appear on hover (same as Chrome, VS).
Set to FLT_MAX to only display a close button when selected (merely hovering is not enough).
Set to an intermediary value to toggle behavior based on width (same as Firefox).
- Backends: Win32: Support for #define NOGDI, won't try to call GetDeviceCaps(). (#3137, #2327)
- Backends: OpenGL: Fixed handling of GL 4.5+ glClipControl(GL_UPPER_LEFT) by inverting the
projection matrix top and bottom values. (#3143, #3146) [@u3shit]
- Backends: Vulkan: Fixed error in if initial frame has no vertices. (#3177)
- Backends: Vulkan: Fixed edge case where render callbacks wouldn't be called if the ImDrawData
structure didn't have any vertices. (#2697) [@kudaba]
- Drag and Drop: Fixed unintended fallback "..." tooltip display during drag operation when
drag source uses _SourceNoPreviewTooltip flags. (#3160) [@rokups]
