Thanks for the fantastic tips. The only question I have left is how can I add logic to prevent an object from being dropped under some circumstances based on the object's state. For example, in your discussion a DataFlavor is defined for java.awt.Button. How could I prevent some "drop enabled" widgets from receiving the drop for Buttons that have a caption of "foo"? I presume it is undesirable and inefficient to serialize the object to test it while the mouse is being dragged... Any thoughts?
