Aha! That was exactly what I needed to implement with the Gtk::Table
containing an array of Gtk::Entry objects! Brilliant solution:

m_Entry[i][j].signal_activate().connect(sigc::bind<int, int>
(sigc::mem_fun(*this, &SudokuCreater::on_entry_activate), i, j)); 

m_Entry[i][j].signal_changed().connect( sigc::bind<int, int>
(sigc::mem_fun(*this, &SudokuCreater::on_entry_changed), i, j));

Works a treat now, thanks!
