FFXIV Reversing Question

[mistahmikey]

Been poking around ffxiv.exe using ida pro for a bit now, and have been educating myself on Window Applications via various internet resources. I have been able to decipher much of the WndProc and SubclassWndProc that ffxiv uses, but I be damned if I can figure out how the code responds to the various control interactions that occur. From everything I have read, it seems that WM_COMMAND messages should be generated by the controls and handled during interactions, but from what I can glean, these messages are being handled by the default message handlers.

So if someone could help me understand where to look to find this sort of code, I would greatly appreciate it.

Thanks!
