You either need to write a custom delegate class or a QItemEditorFactory 
class.  I've never used the QItemEditorFactor, i've just used custom 
delegates.

You'll need to implement createEditor, setModelData, and setEditorData.  You 
can pass your data from the model as a qstringlist, or any custom type 
wrapped as a QVariant(You can even use your own roles if needed). For example 
you could pass a QStringList for the editor role and QString for the Display 
role to use as the current value, which would give you enough info to fill in 
a combo box.

Make sure to call setItemDelegate on the view, passing your custom delegate 
class.
