TreeDropZone enum
Where the pointer lies relative to a candidate drop-target row.
The zone names where the pointer IS, not the depth that results.
above and below each resolve over a chain of legal levels, and
either may fall back to a hidden-interior slot (the inside of a
collapsed or empty container) when every level in that chain is
rejected, so a zone of above can still produce a child slot inside
the row above. Read TreeDropTarget.parentKey and
TreeDropTarget.depth for what was actually resolved.
Values
- above → const TreeDropZone
-
Pointer is in the leading portion of TreeDropTarget.targetKey's row. Normally a sibling slot before it.
- into → const TreeDropZone
-
Pointer is in the middle of the row: the first-child slot of TreeDropTarget.targetKey.
- below → const TreeDropZone
-
Pointer is in the trailing portion of the row. Normally a sibling slot after it, or its first-child slot when it is an expanded parent.
