I want to implement a class in c++ that has a callback.

So I think I need a method that has 2 arguments:

In C++, pointers to class methods are hardly used. The fact that you called in - it is delegates and their use is not recommended. Instead of them, you must use virtual functions and abstract classes. However, C++ would not have been so fond of me, if it not supported completely different concepts of programming. If you still want delegates, you should look towards "boost functional" (part of C + +0 x), it allows pointers to methods of classes regardless of the class name. Besides, in C++ Builder has type __closure - implementation of a delegate at the level of the compiler.

P.S. Sorry for bad English...
