ListModel doesn't emit modelReset when its roles change

    XMLWordPrintable

Details

    Description

      When starting with an empty ListModel, it obviously has no roles. When you add a first element to the model, its roles are generated from the first element. However there are no signals emitted to indicates this role change. I'm not sure if it's a bug but I assumed it would emit a modelReset signal.

      For a filter proxy model connected to this ListModel, this is bothersome since it can't change its own roleNames.
