Hmmmm, not sure about that.

If I open a new connection to any X display, using Xlib rather than GTK,
I can do a request and receive all the keyboard events that are
processed through that display.

This is the code for xkey, a very simple X keyboard sniffer Google
turned up last weekend while trying to figure out how to get around this
problem:

  http://wiki.hping.org/135

That's able to receive key events... again except for when a gtk menu is
open.  (ugh)

So, the above example is providing me hope that there may be some
workaround somewhere that's usable, rather than chucking away 6 months
of coding and writing off any hope of ever having decent learning
materials for GTK based apps. ;->

Regards and best wishes,
