Re: attaching a callback that updates combo_box entries

[Stefan Kost <kost imn htwk-leipzig de>]

A last reply for today,

I've read the API docs and Tims TreeView tutorial and I am still lost.
What use is a GtkTreeRowReference (that refrences a path in a model) when I
can't get hold of the GtkTreeModel.
To me it sound like
  GtkTreeModel *gtk_tree_row_reference_get_model(GtkRowReference *reference);
just has been forgotten. At least it would be just what I need in my case.
I could pass the GtkRowReference as user_data to my callback and in there get
model and path. from model and path in turn I could get the iter.

I have filed it under
http://bugzilla.gnome.org/show_bug.cgi?id=160879

If there is agreement, I add a patch (if needed as implementation is trivial).

Ciao
  Stefan
