| /** |
| * The listener interface for receiving mouse wheel events on a component. |
| * (For clicks and other mouse events, use the <code>MouseListener</code>. |
| * For mouse movement and drags, use the <code>MouseMotionListener</code>.) |
| * <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. |
| * <p> |
| * For information on how mouse wheel events are dispatched, see |
| * the class description for {@link MouseWheelEvent}. |
