C++ Function pointer

I have class thats called game. In the class theres a pointer called m_pDisplay. Its a pointer to a function in the class game. Then another class, CWindow, has a pointer to a game class. In the window class, how do i call the pointer in the game class?

I thought something like... m_pGame is the game pointer.

Code:

---

m_pGame->m_pDisplay()

---

But nope.

Maybe my memory on this is rusty, but that looks fine to me. What's the error message?

Just had a quick look around the net, and it seems that way might be the C-style syntax. Maybe it doesn't work in C++. Try this:

Code:

---

(*m_pGame.*m_pDisplay)();

---

With...

Code:

---

m_pGame->m_pDisplay();

---

I get this error...

Code:

---

window.cpp(125) : error C2064: term does not evaluate to a function

---

With...

Code:

---

(*m_pGame.*m_pDisplay)();

---

I get this error...

Code:

---

window.cpp(125) : error C2065: 'm_pDisplay' : undeclared identifier
window.cpp(125) : error C2297: '.*' : illegal, right operand has type 'int'

---

It says undeclared identifier, but it definitly is a declared identifier cuz in the game class i initilize to point to a function. And m_pDisplay is public.

uhh.. okay... maybe more parentheses are needed? Clutching at straws here....

Code:

---

(*((*m_pGame).m_pDisplay))();

---

I'm sure some of those aren't necessary but I've forgotten exactly what the precedence is.

Nope, ive tried almost everything i can think of and nothing works.

This works...

Code:

---

(m_pGame->*(m_pGame->m_pDisplay))();

---
