You can get the correct XID from the drawing area`s widget->window
using the apis in gdkx.h

The tricky thing with GtkNotebook is that it maps pages on demand, so
if you want to do this trick inside a notebook you need to ensure that
its page has been mapped and realized once (possibly by just showing
that page and realizing the notebook with that page shown).
