Description:

[ CCode ( type_id = "gtk_sorter_get_type ()" ) ]
public class Sorter : Object

Sorter is the way to describe sorting criteria.

Its primary user is SortListModel.

The model will use a sorter to determine the order in which its items should appear by calling compare for pairs of items.

Sorters may change their sorting behavior through their lifetime. In that case, they will emit the changed signal to notify that the sort order is no longer valid and should be updated by calling compare again.

GTK provides various pre-made sorter implementations for common sorting operations. ColumnView has built-in support for sorting lists via the sorter property, where the user can change the sorting by clicking on list headers.

Of course, in particular for large lists, it is also possible to subclass Sorter and provide one's own sorter.
