Implement a Callback to a static C++ Member Function ?

[PuKa]

Hi everyone, it's hard days to understand deeper about function pointer, now i get trouble with that, i need your help, and i very pleasure to know what's wrong i've made. thanks a lot.

#include <iostream>
using namespace std;
class one {
public:
    static void show() { cout << "Hi" << endl; }
};
int main() {
    static void (one::*f)();
    f = &one::show;
    one oo;
    (oo.*f)();
    return 0;
}
//output:
//1.cc: In function ‘int main()’:
//1.cc:9: error: cannot convert ‘void (*)()’ to ‘void (one::*)()’ in assignment

when you declare f, it should just be:

void (*f)();

What you have created is a pointer to a non-static member function. Just FYI.
Oh, and, to add to Elkvis: when you want to call the function, you just do f(), not (oo.*f)(). This is a static member, after all, so it does not "belong" to any instance.

Thanks so much for your helps. Elysia and Elkvis.
