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. -- Damian Yerrick "I refuse to listen to those who refuse to listen to reason."
