Hi.

I use a reorderable Gtk::TreeView. I want to call a method when the list  
is reordered. I connect the rows-reordered signal of the model (a  
Gtk::ListStore).  
I can reoder the list but it seems that the rows-reordered is not send.  
I post an example (see attachment).

How can I call a method when the list is reordered?

Use ‘row-inserted’ and ‘row-deleted’ instead.

[http://library.gnome.org/devel/gtk/stable/GtkTreeModel.html#GtkTreeModel-rows-reordered](http://library.gnome.org/devel/gtk/stable/GtkTreeModel.html#GtkTreeModel-rows-reordered)

Note that this signal is not emitted when rows are  
reordered by DND, since this is implemented by removing  
and then reinserting the row.

## Thanks,

kou

Thank you very much. I will use these two signals.
