Direct Known Subclasses:

RepaintManagerX

public class ForwardingRepaintManager
extends RepaintManager

A RepaintManager that is designed to forward all calls to a contained delegate. This class is designed for extension, such that subclasses should override method as appropriate and allow the original repaint manager to handle the rest of the work.

Install a forwarding repaint manager:

 RepaintManager manager = RepaintManager.currentManager(this);
 RepaintManager frm = new ForwardingRepaintManager(manager);
 RepaintManager.setCurrentManager(frm);
