public class SortListModel : Object, ListModel
`GtkSortListModel` is a list model that sorts the elements of the underlying model according to a `GtkSorter`.
The model can be set up to do incremental sorting, so that sorting long lists doesn't block the UI. See [ method@Gtk.SortListModel.set_incremental] for details.
`GtkSortListModel` is a generic model and because of that it cannot take advantage of any external knowledge when sorting. If you run into performance issues with `GtkSortListModel`, it is strongly recommended that you write your own sorting list model.
