13  * The listener interface for receiving mouse wheel events on a component.
14  * (For clicks and other mouse events, use the <code>MouseListener</code>.
15  * For mouse movement and drags, use the <code>MouseMotionListener</code>.)
16  * <P>
17  * The class that is interested in processing a mouse wheel event
18  * implements this interface (and all the methods it contains).
19  * <P>
20  * The listener object created from that class is then registered with a
21  * component using the component's <code>addMouseWheelListener</code>
22  * method. A mouse wheel event is generated when the mouse wheel is rotated.
23  * When a mouse wheel event occurs, that object's <code>mouseWheelMoved</code>
24  * method is invoked.
25  * <p>
26  * For information on how mouse wheel events are dispatched, see
27  * the class description for {@link MouseWheelEvent}.
