RE: [gtkmm] Gtk::ListStore::insert, i can't get it working :(

Hi Murray,

I'm always posting a little bit to soon ;) I just found out how to do
it:
==================================================================
Gtk::TreeIter test = liststore->children().begin();
//here i can do something with test
row = *(liststore->insert(test) );
==================================================================
So simple and still it took me about 2 hours to find out.....

Anyway, thnks for the reply.

Bart

NB AFAIK something is inserted BEFORE.
