Graphics subclass supporting graphics debugging. Overrides most methods from Graphics. DebugGraphics objects are rarely created by hand. They are most frequently created automatically when a JComponent's debugGraphicsOptions are changed using the setDebugGraphicsOptions() method.
NOTE: You must turn off double buffering to use DebugGraphics: RepaintManager repaintManager = RepaintManager.currentManager(component); repaintManager.setDoubleBufferingEnabled(false);
