Op2 Innern Workings

[Eddy-B]

I been working towards understanding the inner workings of Outpost, and more to the point: IWnd and IDlgWnd.

I did get some information from op2hacker, but i don't know what the others here know about it, so i just got started from blank. I already have some stuff written down, and as soon as i got it neatly organized i'll post it here for the others to view, comment, and add stuff to it.

I have a bit I can add, but not much. I think mostly just heirarchy stuff. Such as what classes derive from what other classes. My notes on this are on my other computer though. I'll try to take a look in a few hours if I have time.


Also, I suspect that those classes aren't complete. I got the feeling that the classes for windowing in OP2Shell.dll just derived from these classes, and implemented the mission functions. I remember there was something to suggest that the classes used by OP2Shell were not quite the same. I think they had a different vtbl, and some of the original entries from the exported classes might have had blank entries in their vtbls. It's been a while since I looked at it, so I could be wrong.

Ok, here's a dump of some of the info I had on those classes. It'll probably look terrible, but it should suggest certain class inheritance.
