GTK windows that are children of Xlib windows

["Richard Davis" <rld2h hotmail com>]

If anyone can help, I'd appreciate it; I'm stumped here.  I've got an X 
window that is full-size, covering up any and all Window manager stuff.  
This is necessary for the app I'm writing, since the absolute corners of the 
screen are being used.  However, I'd like to have popup GTK windows used 
during the course of this process, which I need to have happen on top of the 
fullscreen Xlib window.

Unfortunately, doing the following causes a seg fault:

 XMapWindow(xdpy,wwindow);
 XFlush(xdpy);

 left_window = create_left_window ();
 gtk_widget_show (left_window);


The X fullscreen window shows fine by itself, and the GTK widgets show 
properly themselves.  The combination of the two causes the problem.  I 
think that I need to somehow have the GTK windows be children windows to 
this X fullscreen window.  Does anyone know how to do this in GTK?  All I 
see are TOP_LEVEL, POPUP, and DIALOG type windows in GTK.  What I really 
need (I think) is a type CHILD, so I can tell this that it's the child of 
this Xlib window.

These are some of the failed assertions I got:

 GLib-CRITICAL **: file ghash.c: line 138 (g_hash_table_lookup): assertion 
`hash_table != NULL' failed.

Gtk-WARNING **: gtk_type_create(): unknown parent type `21'.

By the way, trying gdk_window_foreign_new(my_xlib_window) causes a 
segmentation fault.  I thought that if I could get GDK to recognize the 
window, there might be some hope of having GTK process it correctly.

Thanks for any help.
