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
.
