Yes Owen, that's right! I'm new in developing with Gtk+. Sorry
for my wrong ideas i'd posted. That's my way to find the truth.
    
Your posting in this list is 6 days ago and today this part of
my source code is gone to do best results :-)
    
My mistake was to have not anough knowlede about Gtk-callbacks.
The relevant Gtk-callback "row-expanded" from GtkTreeView:
    
(void)g_signal_connect(G_OBJECT(treeView->treeView),
                        "row-expanded",
                        G_CALLBACK(ct_tree_next_level),
                        treeView);
    
My first meaning was that the 'user data' treeView will become
first option for the callback function. Like:
    
void ct_tree_next_level(CtTreeView *treeView) {
    
        (?something?); return; }
    
But after some days i found in Gtk+ API a detailed discription
about the Gtk-callbacks. And relevanted callback (row-expanded)
looks like this:
    
void ct_tree_next_level(GtkTreeView *tree,
                        GtkTreeIter *expandedIter,
                        GtkTreePath *unused,
                        CtTreeView *treeView)
    
Can you see my bloody beginning?
    
regards, mathew
