I've never tried this, but can't you just use an array? For example:

  public:
    std::vector<Gtk::TreeModelColumn<Glib::ustring> > cols;
 	
    ModelColumns(int no)
    {
      for (int i = 0; i < no; ++i) {
        cols.push_back(Gtk::TreeModelColumn<Glib::ustring>());
 	add(cols.back());
      }
    }

I'm not sure whether it works, though. The interface for the treeview
classes is very confusing.
