Not necessarily. In tables and tree's with multiple columns you'll still
get a list unless you active single-item-selection (instead of row or
column-selection) even in single-selection mode (as all indexes of the
single selected row are reported). I guess thats one of the reasons that
QItemSelectionModel has two getters for selected row(s) and selected
column(s).
