Thread: Method pointers and inheritance

I came across a scenario where I need to register class methods from a subclass, however the calls to Register below (obviously) complains about converting wrong types (CSub:: instead of CBase:.

Code:

class CBase;

typedef void (CBase::*Pointer)();

class CBase
{
  public:
    void Register(Pointer P);
};

class CSub : public CBase
{
  public:
    void Method1();
    void Method2();
    void Method3();
};

CSub Sub;

Sub.Register(&CSub::Method1);
Sub.Register(&CSub::Method2);
Sub.Register(&CSub::Method3);

I could of course use plain functions (static methods) and pass a class objects but that wouldn't be very elegant. Is there a correct way to solve this? What happens if I perform a reinterpret_cast?
