Morten, I was doing some work, and have some patches (not yet available) in this area, to do with embedding NSView hierarchies inside QWidgets. The approximate changes are in the Cocoa QPA, to ensure that child QWindows are inserted into the NSView heirarchy as subviews correctly, and re-ordered in the subviews list (by removing and re-adding, as the AppKit docs suggest).

One of the bugs hopefully fixed by this is:

	https://bugreports.qt.io/browse/QTBUG-7140

I can provide the patches via email, but I wonder if they will be subsumed by this work you’re about to start.

Kind regards,
James
