    \fn void QMenuBar::triggered(QAction *action)

    This signal is emitted when a menu action is selected; \a action
    is the action that caused the event to be sent.

    Normally, you connect each menu action to a single slot using
    QAction::triggered(), but sometimes you will want to connect
    several items to a single slot (most often if the user selects
    from an array). This signal is useful in such cases.
