[comp.windows.x] help with handling expose events

I am doing raster graphics and would like to copy from a pixmap 
when the user resizes the application window.

My question is this :
	Since the user can resize the application window to be
	as large as the root window, do I have to create a pixmap
	as large as the root window ?. Is this is the best way to
	do it?. Also, if the user adds some more drawings,  how do
	I update the pixmap. 


Thanx
Uma
