Examples of MouseWheelListener

java.awt.event.MouseWheelListener
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 {@link MouseWheelEvent}. @author Brent Christian @see MouseWheelEvent @since 1.4
org.eclipse.swt.events.MouseWheelListener
Classes which implement this interface provide a method that deals with the event that is generated as the mouse wheel is scrolled.
After creating an instance of a class that implements this interface it can be added to a control using the addMouseWheelListener method and removed using the removeMouseWheelListener method. When the mouse wheel is scrolled the mouseScrolled method will be invoked.
