Class DoubleBuffering

java.lang.Object
  rcx.rcxtools.filebrowser.DoubleBuffering

public class DoubleBuffering
extends java.lang.Object

A smart implementation of double buffering that shares one offscreen image. Set the property "DBdebug" to true to disable double buffering and debug drawings.

Double buffering works only with native container (Panel, Canvas, etc.). To enable double buffering on a Panel, create a Panel like this:

 Panel panel = new Panel () {
      public void update(Graphics g) {
        DoubleBuffering.update(this, g);
      }
    };
