ListBox.setSortFunc

By setting a sort function on the box one can dynamically reorder the rows of the list, based on the contents of the rows.

The sort_func will be called for each row after the call, and will continue to be called each time a row changes (via [gtk.list_box_row.ListBoxRow.changed]) and when [gtk.list_box.ListBox.invalidateSort] is called.

Note that using a sort function is incompatible with using a model (see [gtk.list_box.ListBox.bindModel]).
