Forwarding events to the proper widget

[David Allen <opop erols com>]

If an event is sent to a GTK program, say through some synthetic program
the main window of your program is sent a "X" keypress and then an "X" 
keyrelease, most applications get those, but a lot of times they are 
ignored because they aren't sent to the right widget.

How do you catch signals that are sent to the window, and forward them to 
the right widget?  Does GTK have a method of handling this type of thing or
would it be delving into Xlib, and if so, what book would one recommend for
the Xlib behind GTK?
