Thread: set of pointer to methods!

Hello,

I'm trying to have a STL set of pointer-to-member-functions in my class. I already know how to declare and define pointers-to-functions and use them with an ordinary array, but using the STL containers has proven problematic.

It kind of works with vectors if I choose to use .push_back(), but .insert() gives me errors. That said, I need to use set. So can anyone tell me how to fix this sample code?

Code:

#include <iostream>
#include <set>

using namespace std;

class test{

public:  
  test(){ p.insert( &test::g ); }
  int f(){ cout << " f() " << endl; }
  int g(){ cout << " g() " << endl; }
  int h(){ cout << " h() " << endl; }

  set< int(test::*)() > p;

};


int main(int argc, char *argv[]){

  test a_test;

  ((a_test).*(a_test.begin()))();

}

Thanks
