I'm @ work now ( new job too ) so I can't spend time right now preparing an example, but I have this kind of functionality in Gtk3::Ex::DBI - http://tesla.duckdns.org/gtk3-ex-dbi/ - ( specifically in the Datasheet class ), where the list of items in a combo box are populated by a query, using a value or values from other cells as a filter. Look for stuff related to refresh_dynamic_combos in Gtk3::Ex::DBI::Datasheet. If you're still having issues with it, reply and I'll give you a hand tonight or ASAP.
