| DebugGraphics | | public class DebugGraphics extends Graphics (Code) | | 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);
