Examples of org.eclipse.swt.events.MouseWheelListener

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.
