DebugGraphics (Java Platform SE 8 )

java.lang.Object
- java.awt.Graphics
- - javax.swing.DebugGraphics

```
public class DebugGraphics
extends Graphics
```
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);

See Also:

JComponent.setDebugGraphicsOptions(int), RepaintManager.currentManager(java.awt.Component), RepaintManager.setDoubleBufferingEnabled(boolean)
