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 id parameter of any particular PaintEvent instance is not in the range from PAINT_FIRST to PAINT_LAST.
public static final int PAINT_FIRST
Marks the first integer id for the range of paint event ids.
public static final int PAINT_LAST
Marks the last integer id for the range of paint event ids.
public static final int PAINT
The paint event type.
public static final int UPDATE
The update event type.
