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)

Field Summary

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

isDrawingBuffer

public boolean isDrawingBuffer()

Returns the drawingBuffer value.

Returns:

true if this object is drawing from a Buffer

setDebugOptions

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.
