Thread: derived class member function pointer

is it possible to in the baseclass declare a function-pointer that
will point to a function in the derived class?

like:

Code:

class base {
    void (base::*ptrToFunction)();
}

class derived : public base {
    void doSomething();
    derived(){ptrToFunction=doSomething;};
}

now offcourse I get an "cannot convert from 'void (__thiscall derive::*)()' to 'void (__thiscall base::*)()" error but
is there a way to accomplish this?

thanks
