> On_* procedures are useless most of the time.

I guess you mean in GtkAda? I've found them invaluable in other contexts. If so, that's disappointing. To be fair, in the hours of reading on this I did notice that Gtk+ itself makes this difficult; the On_* procedures seem to be a GtkAda enhancement.

In the end I made it work with an On_* design, but it was your suggestion that helped! I used the second form of On_Edited and passed a TreeView in the slot. To get the model:

      Tree_View: Gtk_Tree_View := Gtk_Tree_View(Self);
      Model: Gtk_Tree_Model := Get_Model( Tree_View );
      Iter     : Gtk_Tree_Iter := Get_Iter_From_String(Model, Path);
      Store: Gtk_List_Store := Gtk_List_Store( To_Object(Model) );

Getting the rest wasn't too hard after I had that. What I hadn't understood at first was that the Model had to be converted from the Interface via the To_Object function.

Thank you very much, and also for the quick answer!

PS If anyone knows how to make the first form of On_Edited work, I'd be delighted to know.
