paint
public void paint(org.eclipse.swt.graphics.GC gc, int x, int y)
Description copied from interface:PrintPiece
Draws this PrintPiece on the given graphics device, at the given coordinates.- Specified by:
paint
in interfacePrintPiece
- Parameters:
gc
- a graphics context for the graphics device.x
- the x coordinate where this PrintPiece will be drawn.y
- the x coordinate where this PrintPiece will be drawn.

dispose
public void dispose()
Description copied from interface:PrintPiece
Disposes the system resources allocated by this PrintPiece. The dispose method is not a permanent disposal of a PrintPiece. It is intended to reclaim system resources, however future calls to paint(GC,int,int) may require that the resources be allocated again.- Specified by:
dispose
in interfacePrintPiece
