32: * The listener interface for receiving mouse wheel events on a component.
33: * (For clicks and other mouse events, use the MouseListener. For mouse
34: * movement and drags, use the MouseMotionListener.)
35: * <P>
36: * The class that is interested in processing a mouse wheel event
37: * implements this interface (and all the methods it contains).
38: * <P>
39: * The listener object created from that class is then registered with a
40: * component using the component's <code>addMouseWheelListener</code>
41: * method. A mouse wheel event is generated when the mouse wheel is rotated.
42: * When a mouse wheel event occurs, that object's <code>mouseWheelMoved</code>
43: * method is invoked.
