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. The TreeModelFilter-DragDest home page is
