I still recommend that you look over the nanowm and pixil code to see how
things like this are done, because you'll end up dealing with many of the
same issues in your application.
For your specific question, you should select on the
GR_EVENT_TYPE_CHLD_UPDATE event for the root window, and look for the subtype
of GR_UPDATE_MAP - this will tell you when a newly created window has been
mapped (and the id of that window).
If you have the pixil code handy, check line 238 of sys/pixilwm/main.c - you
can see how the pixilwm does it.
