The getDragAction method of DragGestureEvent is supposed to return ACTION_COPY, ACTION_LINK, or ACTION_MOVE based on the state of the control and shift modifier keys. The action is actually determined in the DragGestureRecognizer. On windows and unix, ctrl gives ACTION_COPY, and ctrl-shift gives ACTION_LINK.
I haven't tried any of this yet. I'm just now reading the DnD chapter in Core Advanced Swing.....
Not much help, I know. Let me know if you get it to work!

Here's some more:
The acceptDrag method of DropTarget takes an int dragOperation. A decision is made what to do with that value in the body of the method. You could subclass DropTarget if you have something different in mind, other than copying or moving.....
