[sadhees kumar <sadheeskumar gmail com>]

Hello everybody,

                        In my application i draw graphs using
"expose_event" but the screen becomes very slow if i do so.
                    
                        I would like to have a small example program
(to draw a line or box) using pixmap.It will be very helpfull for me.

      Indeed my advance thanks.

regards,
sadhees
