I have written a simple application that draws line segments in a window using *only* Xlib and not the XToolKit.
When a user changes the size of the window with his favorite Window Manager, I want to adjust the size of the graphics to the new size of the window. 

 
	XSelectInput(dpy, win, ExposureMask | ResizeRedirectMask)
   in order to enable my program to be notified when either a "Expose" or    "Resize" event occurs.

2. To get the *new* dimensions of the window. I thought that a call to 
	XGetWindowAttributes(dpy, win, &win_att) would do the job.
The XWindowAttributes win_att structure indeed contains info about the window, but the width and height correspond to the *initial* size of the window, and *not* the new one.

Did I miss something, or what's wrong with the way I do ?

PS: Btw, I created the window with:
	    win = XCreateSimpleWindow(dpy,
			      DefaultRootWindow(dpy),
			      100, 100,
			      dimx, dimy, 
			      2,       /*--- Border width ---*/
			      BlackPixel(dpy, 0), WhitePixel(dpy, 0));
Thanx for any reply ...
