correct design for pointer members of a c++ class in qt design

I want to design and write a class in c++ with qt design pattern. In my original class I just have one data member which is inherited from QSharedData that is named MyClassData, and some member functions. Now my question is if MyClassData includes Pointer, how should I define this Pointer in that class?

The following codes will clear my question:

class MyClassData : public QSharedData {
public:
     MyClassData();
     // one of these pointers is correct ?
     int * myNormalPointer;
     QSharePointer<int> myQSharedPointer;
     QScopedPointer<int> myQScopedPointer;
};
class MyClass {
public:
     MyClass();
     // and some other member functions ...
     QSharedDataPointer<MyClassData> data;
}

If my question will not be closed!, I wanna ask that generally is it correct to always avoid from defining Pointers in member field of a class?
