 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.An unspecified behavior will be caused if the idparameter of any particularPaintEventinstance is not in the range fromPAINT_FIRSTtoPAINT_LAST.- Since:
