To be able to get pointers to class methods in C++, generally you have
to mark the function pointed to as "static" in the class declaration,
which means it doesn't get passed a pointer to `this'.

Seriously, pointers to methods aren't useful unless you're trying to
interface your C++ code with a library written in C (e.g. Allegro or
something).  If you're trying to interface C++ with C++, inheritance
and polymorphism (the `virtual' keyword) provide a cleaner mechanism.
