31 * A listener interface for receiving mouse motion events during a drag
32 * operation.
33 * <p>
34 * The class that is interested in processing mouse motion events during
35 * a drag operation either implements this interface or extends the abstract
36 * {@code DragSourceAdapter} class (overriding only the methods of
37 * interest).
38 * <p>
39 * Create a listener object using that class and then register it with
40 * a {@code DragSource}. Whenever the mouse moves during a drag
41 * operation initiated with this {@code DragSource}, that object's
42 * {@code dragMouseMoved} method is invoked, and the
43 * {@code DragSourceDragEvent} is passed to it.
