I think thats exactly what I needed to hear.

I'm trying to display a GtkKeyboard 
(my custom widget for a touchscreen keyboard)
as a popup. I construct it inside a toplevel 
GtkWindow useing glade. then I try to use it as
a popup with gtk_widget_show().

This means that modal or not ... no widgets can overlap
exept for the GtkWindow.

Thanks alot, If the above is correct
(I'm quite sure now) than I'll figure
something out.
