Thanks Steve, but then I'm having the same problem as with
QList<QObject*> models. In both cases they are accessed in a different
way compared with QML ListModels.
Maybe we could write a generic wrapper like, for example, ListModel<T>
that would expose all properties of the containing type T as roles. Not
sure if that is possible, though. It's just a couple of days since I'm
in Qt land :)
Anyways, I'll read your article - I probably can learn something.
Thanks!
Conny
