GtkColumnViewSorter is a sorter implementation that is geared towards the needs of GtkColumnView.

The sorter returned by columnViewGetSorter is a GtkColumnViewSorter.

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 GtkColumnViewSorter 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 ColumnViewSorter:primarySortColumn and ColumnViewSorter:primarySortOrder.

If you want to store the full sort configuration, including secondary sort columns that are used for tie breaking, then you can use columnViewSorterGetNthSortColumn. To get notified about changes, use Sorter::changed.

To restore a saved sort configuration on a GtkColumnView, 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);
  }
