@ -55,6 +55,18 @@ Other changes:
- Windows: loosened code to allow hovering of resize grips, borders, and table
borders while hovering a sibling child window, so that the code in master matches
one in docking (they accidentally diverged). (#8554)
- TreeNode: added flags to draw tree hierarchy outlines linking parent
and tree nodes: (#2920)
- ImGuiTreeNodeFlags_DrawLinesNone: No lines drawn.
- ImGuiTreeNodeFlags_DrawLinesFull: Horizontal lines to child nodes. Vertical line drawn down to TreePop() position: cover full contents.
- ImGuiTreeNodeFlags_DrawLinesToNodes: Horizontal lines to child nodes. Vertical line drawn down to bottom-most child node.
- Added style.TreeLinesFlags which stores the default setting,
which may be overriden in individual TreeNode() calls.
- Added style.TreeLinesSize (default to 1.0f).
- Added ImGuiCol_TreeLines (in default style this is the same as ImGuiCol_Border).
The color for a given hierarchy level is latched in TreeNode(),
allowing advanced tree drawing code to potentially alter it.
- The feature adds a little cost as extra data needs to be stored.
- Nav: fixed assertion when holding gamepad FaceLeft/West button to open
CTRL+Tab windowing + pressing a keyboard key. (#8525)
- Error Handling: added better error report and recovery for extraneous
