[Dev-C++] pointers to member functions

[michele <mic...@li...>]

Question about pointers:

// A class named 'MyClass' inherits from its parent class a pointer of this
type:

    void (ParentClass::*p)(int variable);

// inside a member function this is right:

    (this->*p)(variable);

// outside (es. in main function):

ChildClass *MyClass=new ChildClass;

 (MyClass->*p)(variable)    // doesn't work (compiler: "p undeclared")


Is It possible to call this type of pointers outside member functions?

Bye

AFAIK, you're probably trying to access a private
variable from within main. i guess 'p' is private in
the child class.

Hi,
I have just controlled:
in Parent class the pointer is public, and the child class is defined as:

class ChildClass: public ParentClass etc...

(It'isn't very elegant, but what I'm doing now is to call an inline function
that contains only that pointer, so I can use it.)

Bye
(afaik?)

AFAIK - A Far A I Know. lol

you can make it protected in the parent class, and use
an accessor method to call it. if you inherit as
public, it remains protected in the child class.
(protected is much like private, except derived
classes can access them. derived classes cannot access
private members). if you inherit as private,
everything inherited (public and protected members)
become private to the derived class.
