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
}
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
}
