/**
 * This adapter class provides default implementations for the
 * methods described by the DropTargetListener interface.
 * 

* Classes that wish to deal with DropTargetEvents can * extend this class and override only the methods which they are * interested in. *

* *

* Please note, there are subtle difference in DND behavior on different OS's. * For example during a file transfer, Windows will put out the file path * as soon as the drag begins, where as Linux will make it available only * on a drop operation. For correct crossplatform behavior, it is recommended * to delay OS interaction until drop has occurred or verify the correctness of * the operation across platforms. *
