Thanks. This is exactly what I was looking for! I didn't realize that a
combobox can be attached to a model, and that a model can be filtered.
Imo multiple partial string match should be default behavior, which it is
unfortunately not. E.g. inkscape only matches in the beginning of the
string.
Is there a GNOME guide line about this?
Regards,
Dov
