setSortFunc

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

The @sort_func will be called for each child after the call, and will continue to be called each time a child changes (via method@Gtk.FlowBoxChild.changed) and when method@Gtk.FlowBox.invalidate_sort is called.

Note that using a sort function is incompatible with using a model (see method@Gtk.FlowBox.bind_model).
