Any ideas how to avoid this and still return a reference? Or could I return a smartreturning "const QModelIndex &" should be save. But you could also return may value, copying QModelIndex isn't that expensive. The Qt code return often by value, QModelIndex was designed for this.
Unfortunately, I can't return const. I'll try returning by value.
