Known Direct Subclasses
org.eclipse.swt.dnd.DropTargetEffect
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.
