Hi Frank, What does the standard delegate do for your model/view at the moment? I can't recall the specifics, but it certainly uses combo boxes at the moment - eg, for boolean fields (which I think is painful, but anyway).
I think you need to give more information about what you are expecting. For example, you include 'insert' as an action. But what does this mean? If a user types an entry not already in the list, what do you expect to happen? Which table would the new entry be inserted into? Where should the combo box get its values from? Yes I agree that the model view classes take a while to grok.
