Yes, now it works. Thanks!

However, it appears that this is not something suitable for the task, 
since this particular event "edited" (GtkCellRender) is triggered after 
the editing has finished. As a result, I get -1 with 
gtk_tree_view_column_get_sort_column_id (focus_column).

So I've tried out your original technique, but I'm having some issues 
there --

I'm comparing the passed over GtkCellRenderer * with all renderers as 
such --

    while ( mod_renderer != *(renderer + i) )
        i++;

Where mod_renderer is the passed over GtkCellRenderer and renderer is  --

GtkCellRenderer **renderer;

and allocated memory via --

GtkCellRenderer **renderer = g_malloc (sizeof (GtkCellRenderer*) * 2);
    renderer[0] = gtk_cell_renderer_text_new ();
    renderer[1] = gtk_cell_renderer_text_new ();

I'm getting sefault in the while loop.
