  13.  * The listener interface for receiving mouse motion events on a component.

  14.  * (For clicks and other mouse events, use the <code>MouseListener</code>.)

  15.  * <P>

  16.  * The class that is interested in processing a mouse motion event

  17.  * either implements this interface (and all the methods it

  18.  * contains) or extends the abstract <code>MouseMotionAdapter</code> class

  19.  * (overriding only the methods of interest).

  20.  * <P>

  21.  * The listener object created from that class is then registered with a

  22.  * component using the component's <code>addMouseMotionListener</code> 

  23.  * method. A mouse motion event is generated when the mouse is moved

  24.  * or dragged. (Many such events will be generated). When a mouse motion event

  25.  * occurs, the relevant method in the listener object is invoked, and 

  26.  * the <code>MouseEvent</code> is passed to it.
