Thanks for replying. This makes sense. Sorry if it is just me who is 
being stupid here, but: If I'm going to call row_inserted for instance, 
I need a Gtk::TreeModel::Path and a Gtk::TreeModel::iterator object to 
pass to it. These - it seems - needs to be generated from the new 
element in my vector.

It looks like the path can be created from the iterator, but I cannot 
see how I should generate the iterator. Could anyone give me an example 
or perhaps point me to one?

Thanks in advance,
Tor Arvid Lund
