That event is your problem itself. This is a native X-Event, that is wrapped 
by Gtk+/gtkmm. If you want this event to be activated you must call 
Gtk::Widget::add_events(Gdk::BUTTON_PRESS_MASK);

Here is the modified source part:

HelloWorld::HelloWorld() : 
  m_button("Hello World")
{
  add(m_button);
  m_button.show();
  m_button.add_events(Gdk::BUTTON_PRESS_MASK);
  m_button.signal_button_press_event().connect(
    SigC::slot(*this, &HelloWorld::on_button_press));
}
