Class PaintEvent
java.lang.Object
java.util.EventObject
java.awt.AWTEvent
java.awt.event.ComponentEvent
java.awt.event.PaintEvent
- All Implemented Interfaces:
- Serializable
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.
