public class DebugGraphics

extends java.awt.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.

setDebugGraphicsOptions

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.
