[Interest] How can I use QPointer as an argument?

[Constantin Makshin]

QPointer is a template class and therefore can't be used by itself, i.e.
without specifying the template parameter.

In your case you should either:
1) specify a particular QObject-related class in the
declaration/definition of myFunction(), e.g.
   void myFunction (QPointer<QWidget>* myPointer)
   {
       // do something
   }
2) define myFunction() as a template function, e.g.
   template <class T>
   void myFunction (QPointer<T>* myPointer)
   {
       // do something
   }
