Gets whether the model is passing through original row items.
If this function returns %FALSE, the GListModel functions for @self
return custom GtkTreeListRow objects. You need to call
[method@Gtk.TreeListRow.get_item] on these objects to get the original
item.
If %TRUE, the values of the child models are passed through in their
original state. You then need to call [method@Gtk.TreeListModel.get_row]
to get the custom GtkTreeListRows.
