You can do funky stuff with SigC::bind and pointers. Perhaps it can
help here. For example:

  void PreferencesWindow::on_checkbutton_changed(Gtk::CheckButton *checkbutton,
					         Glib::ustring key)
  {
    // process checkbutton, using key
  }

  PreferencesWindow::PreferencesWindow()
  {
    // ...

    checkbutton->signal_toggled()
      .connect(SigC::bind(SigC::slot(*this, &PreferencesWindow::on_checkbutton_changed),
			checkbutton, key));
    // ...
  }
