When doing drag-and-drop inside NSOutlineView, who is responsible for
showing "green plus sign" over dragged image and do I need to do
anything special to make it happen? It looks like it is "drop
destination" responsibility. Is
- (unsigned int)outlineView:(NSOutlineView*)olv validateDrop:(id
<NSDraggingInfo>)info proposedItem:(id)item proposedChildIndex:(int)
childIndex
right place to deal with it?
Thanks,
Andrei
