- Drag and Drop: Fixed submitting a tooltip from drop target location when using AcceptDragDropPayload()
|
||||
with ImGuiDragDropFlags_AcceptNoPreviewTooltip and submitting a tooltip manually.
|
||||
- TreeNode: Added ImGuiTreeNodeFlags_SpanAllColumns for use in tables. (#3151, #3565, #2451, #2438)
|
||||
- Tables: Added ImGuiTableFlags_HighlightHoveredColumn flag, currently highlighting column header.
|
||||
- Tables: Fixed an edge-case when no columns are visible + table scrollbar is visible + user
|
||||
code is always testing return value of TableSetColumnIndex() to coarse clip. With an active
|
||||
clipper it would have asserted. Without a clipper, the scrollbar range would be wrong.
|
||||
- Tables: Request user to submit contents when outer host-window is requesting auto-resize,
|
||||
so a scrolling table can contribute to initial window size. (#6510)
|
||||
- Tables: Fixed subtle drawing overlap between borders in some situations.
|
||||
- Tables: Fixed bottom-most and right-most outer border offset by one. (#6765, #3752) [@v-ein]
|
||||
- Tables: Fixed top-most outer border being drawn with both TableBorderLight and TableBorderStrong
|
||||
in some situations, causing the earlier to be visible underneath when alpha is not 1.0f.
|
||||
- Tables: fixed right-clicking right-most section (past right-most column) from highlighting a column.
|
||||
- Tables:
|
||||
- Added angled headers support. You need to set ImGuiTableColumnFlags_AngledHeader on selected
|
||||
columns and call TableAngledHeadersRow(). Added style.TableAngledHeadersAngle style option.
