C++ (Cpp) QMetaProperty::readOnGadget示例

void tst_QMetaProperty::gadget()
{
    const QMetaObject *mo = &MyGadget::staticMetaObject;
    QMetaProperty valueProp = mo->property(mo->indexOfProperty("value"));
    QVERIFY(valueProp.isValid());
    {
        MyGadget g;
        QString hello = QLatin1Literal("hello");
        QVERIFY(valueProp.writeOnGadget(&g, hello));
        QCOMPARE(g.m_value, QLatin1String("hello"));
        QCOMPARE(valueProp.readOnGadget(&g), QVariant(hello));
        QVERIFY(valueProp.resetOnGadget(&g));
        QCOMPARE(valueProp.readOnGadget(&g), QVariant(QLatin1String("reset")));
