changed

Notifies all users of the sorter that it has changed.

This emits the signal@Gtk.Sorter::changed signal. Users of the sorter should then update the sort order via method@Gtk.Sorter.compare.

Depending on the @change parameter, it may be possible to update the sort order without a full resorting. Refer to the enum@Gtk.SorterChange documentation for details.

This function is intended for implementors of GtkSorter subclasses and should not be called from other functions.
