draw line in gtk

[Utpal Shasane <shasane_utpal extenprise net>]

Hi,
I drawn line using 
                                       gdk_draw_line 
(draw->window,draw->style->fg_gc[GTK_WIDGET_STATE(draw)],23,20,23,450);
on drawing area widget. But, it comes once and vanishes. When i called 
gtk_timeout_add() function it
is contineous. Can somebody tell me, how i can draw a line without using 
gtk_timeout_add().

thanks,
\Utpal
