Using 'this' in Initializer List?

This could have to do with windows programming, as it could have to do with the specifics of how I'm using the this pointer, however, I'm gonna ask here. KK. K. Here's how it's all laid out.

Code:

---

window procedure - recieves 'this' of OGL manager in lpCreateParams

opengl class - has-a window class which takes lpCreateParams as a constructor arg
window class - creates window using window procedure and the create params it recieves from opengl class


class w {w(LPVOID createparams) { createwindow(use wndproc, createparams); }
class ogl { friend LRESULT wndproc(blah, blah); window _w; ogl() : _w(this) { } };
LRESULT wndproc(blah, blah) { uses some private routines of ogl; }

---

I get a warning from passing the this of my ogl class to my window class:

Code:

---

warning C4355: 'this' : used in base member initializer list

---

Wot? How dangerous, bad, and crazy is this potentially? Workarounds?

Look up the warning?

Wow that's some ugly code right there. You know, putting all the code on one line does not make it faster, better or anything. Indent it.

The problem is that you are passing a pointer to an object that is not even constructed to another object.

>> How dangerous, bad, and crazy is this potentially? Workarounds?
It would be fine as long as you were just storing the value for later use and not actually calling methods from the pointer. If you are actually trying to use member functions or variables of the object before its constructor is called, then you could have issues.

I figurred out a workaround. Thanks n.e.w.a.y.s.

It's psuedo-code :<
