I have a drag and drop JTree that implements DragGestureListener, DragSourceListsner and DropTargetListener. I am trying to add a MouseListener so when a person executes a right-click they can get some data from the nodes of the tree.

I guess my question is where do I implement the MouseListener? I have tried doing so in my DataNode (an extended DefaultMutableTreeNode) and in my tree (an extended JTree) as well as in my abstract classes handling the DnD function.

Nothing I have tried so far seems to register any mouse event. In fact, the tree continues to function with it�s DnD abilities.
