Why not? You don't have to cast it to QMovie* to use it...

But you will have to implement every method, so there is no benefit in using QMovie.

#include <iostream>
 
class A
{
   public:
      void foo() { bar(); }
      void bar() { std::cerr << "A::bar()" << std::endl; }
};
 
class B : public A
{
   public:
      void bar() { std::cerr << "B::bar()" << std::endl; }
};
 
int main()
{
   B b;
   b.foo();
   b.bar();
   return 0;
}

#include <iostream>

class A
{
   public:
      void foo() { bar(); }
      void bar() { std::cerr << "A::bar()" << std::endl; }
};

class B : public A
{
   public:
      void bar() { std::cerr << "B::bar()" << std::endl; }
};

int main()
{
   B b;
   b.foo();
   b.bar();
   return 0;
}
