如何绑定多个action到一个slot

1.设置userdata，并将多个action绑定到同一个slot 
 a->setData(action); //这里的action可以是一个qvariant值

    connect(a, SIGNAL(triggered(bool)),
            this, SLOT(actionslot(bool)));

void actionslot(bool)
{
   QAction *a = qobject_cast<QAction *>(q->sender());
    if (!a)
        return;
    int action =a->data().toInt(); ／／通过这里来区分是哪个actiontriggered
    //do something your own
}
