Here is a simple but complete example of the use of Hildon::Notification:

  // Create a new notification:

    Hildon::Notification::create("Something Happened", 
      "A thing has just happened.", 
      Gtk::Stock::OPEN);

  // Show the notification:

  }
  catch(const Glib::Error& ex)

int main(int argc, char *argv[])
{
  // Initialize gtkmm and maemomm:
  Gtk::Main kit(&argc, &argv);
  Hildon::init();
  Hildon::notify_init("Notification example");

  // Initialize D-Bus (needed by hildon-notify):

  // Show a window with a button:

  Hildon::Program::get_instance()->add_window(window);

  Gtk::VButtonBox box;
  Hildon::Button button(Gtk::Hildon::SIZE_HALFSCREEN_WIDTH | Gtk::Hildon::SIZE_FINGER_HEIGHT,
                        Hildon::BUTTON_ARRANGEMENT_VERTICAL,

  button.signal_clicked().connect(sigc::ptr_fun(&on_button_show_notification));
  
  // Begin the application
  kit.run(window);
  
  return 0;
