I planned working on this as well, but I actually didn't find the time yet
to do anything about it... some of my applications require it, so I have a
real need, but I decided to will stay with Qt 4.8+ until that's resolved.

I made a similar suggestion earlier, and I do have some hacky code that
actually works on Windows to some extend (on Mac OS X there's
QMacCocoaViewContainer, but I've never used it and I have no idea what its
current plan for Qt 5 is).

Anyway, I think that creating a platform independent solution would be
very nice and cool, though I think we should first make old code available
in Qt 5 (so old code will continue to work) and then perhaps add an
abstraction layer later.
