I've got a table view that I would like to allow filtering, editing and still use the relation sql table model I'm using.

When I set the views model to the source model, I get the dropdown box for foreign keys as I should. Thus I know the underlying code regarding relation modeling works. But when I change it to the QSortFilterProxyModel instance, the dropdown boxes go away.

Is it possible using standard Qt to achieve this? I'd prefer to keep it pretty standard.

If not doable using standard stuff, what all would be involved in making it work?
