Setting property based on role

Its the ‘property’ part I want to call dynamically. I.e. in my class I’ve got properties named, “key”, “value”, “section”. The table then displays those values. Role in this case contains one of those values and so I want to set the appropriate property based on that role. If I was using the ListModel I would be able to do this by calling setProperty on the model. You did give me an idea though. Maybe I can expose the QObject::setProperty method to QML
