TreeListRowSorter

open class TreeListRowSorter(pointer: <Error class: unknown class><<Error class: unknown class>>) : Sorter

GtkTreeListRowSorter is a special-purpose sorter that will apply a given sorter to the levels in a tree.

Here is an example for setting up a column view with a tree model and a GtkTreeListSorter:

column_sorter = gtk_column_view_get_sorter (view);
sorter = gtk_tree_list_row_sorter_new (g_object_ref (column_sorter));
sort_model = gtk_sort_list_model_new (tree_model, sorter);
selection = gtk_single_selection_new (sort_model);
gtk_column_view_set_model (view, G_LIST_MODEL (selection));
