使用QMetaObject获取类的属性

const QMetaObject *metaobject = object->metaObject();
int count = metaobject->propertyCount();
for (int i = 0; i < count; ++i) {
    QMetaProperty metaproperty = metaobject->property(i);
    const char *name = metaproperty.name();
    QVariant value = object->property(name);
    qDebug() << name << value;
}
