Thanks Jan-Marek,

I've experimented with the above 'hack'.
Unfortunately no toggle_button is found during the child-scan.
Actually the scan found only one widget in the gtkcomboboxentry, which 
to me seems quite strange as I would have expected at least two.
(Checke by setting another print-statement in the scan_children())

I haven't been able to determine which widget it actually detected, as I 
hevent found any good way of getting the type extracted from the widget 
in a human readable way.

Do you have any clue on what is going on here?

(Also things like the GTK_IS_TOGGLE_BUTTON() macro is not found in the 
documents - okay, it is defined in the header-file, but it is missing in 
the GTK+ Reference Manual for GtkToggleButton)
