public interface MouseWheelListener
extends EventListener sample code for java.util.EventListener definition code for java.util.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 sample code for java.awt.event.MouseWheelEvent definition code for java.awt.event.MouseWheelEvent .
