Class RepaintManager.RepaintWorker

Enclosing Class:
RepaintManager
Implemented Interfaces:
Runnable

protected class RepaintManager.RepaintWorker
extends Object
implements Runnable

A helper class which is placed into the system event queue at various times in order to facilitate repainting and layout. There is typically only one of these objects active at any time. When the RepaintManager is told to queue a repaint, it checks to see if a RepaintManager.RepaintWorker is "live" in the system event queue, and if not it inserts one using SwingUtilities.invokeLater(Runnable).

When the RepaintManager.RepaintWorker comes to the head of the system event queue, its run() method is executed by the swing paint thread, which revalidates all invalid components and repaints any damage in the swing scene.
