Description [src]
final class Gtk.ColumnViewSorter : Gtk.Sorter
{
/* No available fields */
}GtkColumnViewSorter is a sorter implementation that
is geared towards the needs of GtkColumnView.
The sorter returned by gtk_column_view_get_sorter() 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 GtkColumnViewSorter:primary-sort-column
and GtkColumnViewSorter:primary-sort-order.
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_get_nth_sort_column().
To get notified about changes, use GtkSorter::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);
}
