Gtk.TreeModel::row-deleted

function callback(tree_model, path:Gtk.TreePath, ):void;

This signal is emitted when a row has been deleted.

Note that no iterator is passed to the signal handler, since the row is already deleted.

This should be called by models after a row has been removed. The location pointed to by path should be the location that the row previously was at. It may not be a valid location anymore.
