QVariant to QAxObject*

I have QVariant value. It tapeName() == "QAxObject*".
How can I convert this QVariant value to QAxObject*?

This doesn't work:

Code:

---

QVariant v = ....; // Here I init my QVariant value
QAxObject* axObject = v.value<QAxObject*>();

---

It return a compiler error: 'qt_metatype_id' : is not a member of 'QMetaTypeId<T>'

Code:

---

int qRegisterMetaType ( const char * typeName )
