Help with expanding nodes during DnD Drop in JTree
Hello!
I am trying to get my Drag and Drop in JTree method work a little better, and a little more like Windows Explorer.
When I drag from my source and hoovers the mouse over my JTree, it selects the node I am hoovering over, which is all good. However, IF the user stays hoovered over a node (that has collapsed children) ~1 second, I would like that node to be expanded, so the user may drop it onto a child, or expand a child even further.
This should only take place when I am actually dragging something to the tree, and not just hoovering with the mouse cursor.
This behaviour is very common in applications these days and to me it seems like this *should* be availible with some clever TreeSelectionListener or similar, but I can't find anything that seems to help. I dont really feel like implementing a mouse listener, and wait for "stayed on the same node for 1 second" event types :)
