Just for some more information:

toolUndo->signal_button_press_event().connect(sigc::mem_fun(*this,&MainWindow::nothingClick));

doesn't do anything either (it does compile, just like the other one)
nothingClick is:

bool MainWindow::nothingClick(GdkEventButton* event){
  std::cout << "nothing to click" << std::endl;
  return false;
}
