Receiving events on a gdk window.

[Michel Van den Bergh <michel vandenbergh uhasselt be>]

Hello,

I am trying to write an xscreensaver using gtk (pygtk really). An 
xscreensaver must draw on an
externally supplied X window (either supplied on the command line or as 
a virtual root). 

Can somebody explain to me how to make such an externally supplied 
window react to exposure events?  I do know
how to draw on them.

The gtk connect method seems to work only with widgets, not gdk windows.

Best regards,
Michel
