JTree, SelectionModel and Drag&Drop

[Thomas Kellerer]

Hi,

I have a JTree where I allow multiple leafs to be selected and moved from their
original parent node to another node. This is working fine - basically.

The problem is with the SelectionModel: after I have selected e.g. 3 leafs, and
then try to drag them to a different parent node, the first click that is
required to start the drag will de-select all leafs except the one that I
clicked on. When I hold down the Ctrl-Key while clicking everything is fine
(drag & drop works without problems, it's the selection that is the problem)

Now my question is: how do I configure the DefaultTreeSelectionModel to change
the selection on the mouseReleased event not on the mouseClicked event?

Basically I only want the selection to change when the user really clicked
(pushed & released) the mouse button, not when pressing and keeping the button
pressed

Regards
Thomas
