Yep, I've done this before but it was an evil, awful hack and I don't have the patch anymore (probably just as well) :)
The way I did it was just to redirect the first created window, but again, it was hacky. Hopefully you can find a better way.

Hi.
While waiting for the commit of my localspl-Patches, i want to picked up an fun project:
Has anyone an Idea, how to modify "user32.dll" and "winex11.drv" to open a Window, when I already have the X11 Window-ID (example: XSCREENSAVER_WINDOW=0x280020)?
My Idea is to include the wrapper code in explorer.exe and use similar code as already present for "/desktop".
The Window width and height is not known on startup and does not match a well-known Desktop Size. I think, I need to add an Export to winex11.drv to fetch the size and reuse "X11DRV_create_desktop()" or add an Export to someting similar as "X11DRV_create_desktop()".
The client registers a Window Class with a known name ("WindowsScreenSaverClass") and then CreateWindowEx must be redirected to the already created X11-Window.
A lightwight solution might be to implement minimal features from "scrsave.lib" (RegisterClass) in "explorer.exe" and then call "ScreenSaverProc" directly.
Any Ideas?
