Then we follow the approach from this

Custom painting on top of a QML item. That should certainly be possible
since you just make the WindowPreview in C++ and let it paint on a QML
item. Perhaps nasty but that probably works.

I could be a bit naive, but i don't really see an issue on getting the
preview to QML. Perhaps i still need to hit a big giant wall that stops me.
