Thank you for your reply. However, it's not exactly what I was looking for. I don't think I was clear enough in my question, so here's a simple example :

 cplusplus Syntax (Toggle Plain Text) 
class Button {
    public :
        Button(etc, etc, etc, void (*action)());
        void onPressed() { *action(); }
};
 
void randomAction() {
    // Some code
}
 
int main() {
 
    ObjectA A;
    ObjectA AA;
    ObjectB B;
    ObjectC C;
 
    Button b(etc, etc, etc, &A.action); // isn't allowed by C++ ISO
    Button b(etc, etc, etc, &B.action); // isn't allowed by C++ ISO
    Button b(etc, etc, etc, &randomAction); // is allowed by C++ ISO
 
    // Other code
 
    return 0;
}
class Button {
    public :
        Button(etc, etc, etc, void (*action)());
        void onPressed() { *action(); }
};

void randomAction() {
    // Some code
}

int main() {

    ObjectA A;
    ObjectA AA;
    ObjectB B;
    ObjectC C;

    Button b(etc, etc, etc, &A.action); // isn't allowed by C++ ISO
    Button b(etc, etc, etc, &B.action); // isn't allowed by C++ ISO
    Button b(etc, etc, etc, &randomAction); // is allowed by C++ ISO

    // Other code

    return 0;
}

So what I want to do, is execute an action ON ANY KIND OF SPECIFIC OBJECT i want, when the button is pressed. Which is not allowed by the C++ ISO, which says :

Quote:

error : ISO C++ forbids taking the address of a bound member function to form a pointer to member function. Say ‘&ObjectA::action’

But saying "&ObjectA::action" WILL NOT alter the specific object ("A" in this case), it will only call ObjectA::action(), not A.action().

Hope you guys understand better now

Any suggestions?
