I'm implementing DnD in an NSBrowser for 10.4. The Problem I have is
to enable the Column selection (Blue line around the column), to show
to the user that the drag-in is indeed working + its destination. I'm
thinking in the line of using – draggingUpdated from my NSMatrix
subclass used in the Browser to trigger that highlight.
1) How can highlight a specific column in the NSBrowser?
2) The other problem I see is that draggingUpdated is only triggered
as the drag moves within the NSMatrix, not the entire column which
includes the NSMatrix.
Any help really appreciated
