public class PaintEvent
extends ComponentEvent sample code for java.awt.event.ComponentEvent definition code for java.awt.event.ComponentEvent

The component-level paint event. This event is a special type which is used to ensure that paint/update method calls are serialized along with the other events delivered from the event queue. This event is not designed to be used with the Event Listener model; programs should continue to override paint/update methods in order render themselves properly.

Since:
1.1
