TreeListModel.getPassthrough

Gets whether the model is passing through original row items.

If this function returns false, the [gio.list_model.ListModel] functions for self return custom [gtk.tree_list_row.TreeListRow] objects. You need to call [gtk.tree_list_row.TreeListRow.getItem] 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 [gtk.tree_list_model.TreeListModel.getRow] to get the custom [gtk.tree_list_row.TreeListRow]s.
