/**
 * A listener interface for receiving mouse motion events during a drag

 * interest). 
 * <p>
 * Create a listener object using that class and then register it with 
 * a <code>DragSource</code>. Whenever the mouse moves during a drag
 * operation initiated with this <code>DragSource</code>, that object's
 * <code>dragMouseMoved</code> method is invoked, and the
 * <code>DragSourceDragEvent</code> is passed to it.
