Here is what I did last week..

class MyClass
{
...
public:
typedef QList<VTKObjPtr>	VTKObjPtrList;
protected:
VTKObjPtrList			m_lstVTKObjects;

..
}

Then just create the object like this:

MyClass:SomeMember()
{
  vtkSmartPointer<vtkImageEllipsoidSource> pImageSource =
vtkSmartPointer<vtkImageEllipsoidSource>::New();
  m_lstVTKObjects.append(pImageSource);
}
