No, you will have to instantiate as many widgets as there are rows anyway. You can't set the same widget in multiple cells. Anyway, what does this cell widget do? Keep in mind that they are expensive to maintain and that flooding your view full of them makes the model-view framework useless.
Just curious, what do you need that information for? It's the delegate who creates the editor.And one more, I couldn't figure a way to findout when an editing is started in certain cell?
