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