getPassthrough

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.
