Well, as 50 people have looked at this since I posted it (at this time of this writing), and there have been no replies, can I assume that this is either:
  • A bug
  • Not something that Qt is expected to do?


If anyone could confirm either of those, that would be quite helpful in and of itself.

Here's another thread where wysota (who has > 22,500 posts on this forum), suggests that WRITEing to a containerized Q_PROPERTY is perfectly valid. He even provides code that he claims will work (but doesn't). wysota has commented in the other threads I linked to above as well, so even a veteran poster thinks this should work.

OTOH, is there something obvious I am missing?
