Drag and drop between 2 Jtrees

Question

In my application I have 2 JTree controls in a JPanel. How can I transfer data between them, so that the items from the source tree are removed.

Answer 1

Write appropriate subclasses of javax.swing.TransferHandler for both trees. Use TransferHandler.MOVE as the source action. Override exportDone() and see if the action includes the MOVE flag. If so, delete the object represented by the Transferable.
