java.lang.Object java.awt.dnd.DragSourceAdapter
An abstract adapter class for receiving drag source events. The methods in this class are empty. This class exists only as a convenience for creating listener objects.
Extend this class to create a DragSourceEvent listener and override the methods for the events of interest. (If you implement the DragSourceListener interface, you have to define all of the methods in it. This abstract class defines null methods for them all, so you only have to define methods for events you care about.)
Create a listener object using the extended class and then register it with a DragSource. When the drag enters, moves over, or exits a drop site, when the drop action changes, and when the drag ends, the relevant method in the listener object is invoked, and the DragSourceEvent is passed to it.
The drop site is associated with the previous dragEnter() invocation if the latest invocation of dragEnter() on this adapter corresponds to that drop site and is not followed by a dragExit() invocation on this adapter.
