Gtk2-Ex-TreeModelFilter-DragDest adds the TreeDragDest interface to GtkTreeModelFilter objects. As of Gtk 2.12 a filtered model is a drag source, but not a drag destination. With DragDest you can drag and drop to re-order rows in a TreeView. The code here takes two forms, * A TreeModelFilter::Draggable subclass of TreeModelFilter, for use wherever you would have had a plain filter. * The DragDest code separately, to mix-in to any TreeModelFilter derivative you might further subclass. The only prerequisite is Gtk2-Perl.
