      public interface MouseWheelListener
      extends EventListener

  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`.)

  The class that is interested in processing a mouse wheel event implements this interface (and all the methods it contains).

  The listener object created from that class is then registered with a component using the component's `addMouseWheelListener` method. A mouse wheel event is generated when the mouse wheel is rotated. When a mouse wheel event occurs, that object's `mouseWheelMoved` method is invoked.

  For information on how mouse wheel events are dispatched, see the class description for `MouseWheelEvent`.
