In column views, sorting can be configured by associating
sorters with columns, and users can invert sort order by clicking
on column headers. The API of gtk.column_view_sorter.ColumnViewSorter is designed
to allow saving and restoring this configuration.
If you are only interested in the primary sort column (i.e. the
column where a sort indicator is shown in the header), then
you can just look at property@Gtk.ColumnViewSorter:primary-sort-column
and property@Gtk.ColumnViewSorter:primary-sort-order.
gtk.column_view_sorter.ColumnViewSorter is a sorter implementation that is geared towards the needs of gtk.column_view.ColumnView.
The sorter returned by gtk.column_view.ColumnView.getSorter is a gtk.column_view_sorter.ColumnViewSorter.

If you want to store the full sort configuration, including secondary sort columns that are used for tie breaking, then you can use gtk.column_view_sorter.ColumnViewSorter.getNthSortColumn. To get notified about changes, use gtk.sorter.Sorter.changed.
To restore a saved sort configuration on a gtk.column_view.ColumnView, use code like:
sorter = gtk_column_view_get_sorter (view); for (i = gtk_column_view_sorter_get_n_sort_columns (sorter) - 1; i >= 0; i--) { column = gtk_column_view_sorter_get_nth_sort_column (sorter, i, &order); gtk_column_view_sort_by_column (view, column, order); }
