Extends: Graphics
Details
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);

Fields
final public static int LOG_OPTION
Log graphics operations.
final public static int FLASH_OPTION
Flash graphics operations.
final public static int BUFFERED_OPTION
Show buffered operations in a separate Frame.
final public static int NONE_OPTION
Don't debug graphics operations.

public void setDebugOptions(int options)
Enables/disables diagnostic information about every graphics operation. The value of options indicates how this information should be displayed. LOG_OPTION causes a text message to be printed. FLASH_OPTION causes the drawing to flash several times. BUFFERED_OPTION creates a new Frame that shows each operation on an offscreen buffer. The value of options is bitwise OR'd into the current value. To disable debugging use NONE_OPTION.
