- public class PaintEvent
- extends 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.
