QSignalMapper 使用方法 参见QSignalMapper中使用文档

TestServiceDlg1::TestServiceDlg1(const QStringList &texts,QWidget* parent)
    : QWidget(parent)
{
    this->setObjectName(QObject::tr("TestServiceDlg1"));
    m_pageRes.setupUi(this);//!  Ui::pageCustomizePopular 是UI界面对象

    signalMapper = new QSignalMapper(this);

        QGridLayout *gridLayout = new QGridLayout;
        for (int i = 0; i < texts.size(); ++i) {
            QPushButton *button = new QPushButton(texts[i]);

            connect(button, SIGNAL(clicked()), signalMapper, SLOT(map()));
            signalMapper->setMapping(button, texts[i]);

            m_pageRes.gridLayout_AllParams->addWidget(button, i / 3, i % 3);
        }

        connect(signalMapper, SIGNAL(mapped(QString)),
                this, SIGNAL(testclicked(QString)));

        connect(this, SIGNAL(testclicked(QString)),
                this, SLOT(testclickedSlot(QString)));

        //setLayout(gridLayout);
}
void TestServiceDlg1::testclickedSlot(QString s)
{
    QMessageBox msgBox;
    msgBox.setText(s);
    msgBox.exec();

}

class TestServiceDlg1 : public QWidget
{
    Q_OBJECT
public:
    explicit TestServiceDlg1(const QStringList &texts, QWidget* parent = NULL);
    virtual ~TestServiceDlg1();
public:
    Ui::TestServiceDlgUI1 m_pageRes; //!  Ui::pageCustomizePopular 是UI界面对象
private:
    Q_DISABLE_COPY(TestServiceDlg1)
    QSignalMapper* signalMapper;

 protected Q_SLOTS:
signals:
    void testclicked(const QString &text);
private slots:
    void testclickedSlot(QString s);
};

下面是用QACTION完成 QStackedWidget 的界面切换
