It's certainly one of the uglier gotchas people run into. Here is my humble attempt to document it more prominently:


Anyhow, adding stuff to the documentation only helps so much, since people also have to read it :)

In general, I consider deriving from Q*Application sort of an anti-pattern. You fall for it because, hey, you're writing 'application logic' , so the logic should go into something derived from *Application. Anyhow, unless you're really overriding one of the virtual methods there's just no reason to subclass. Just put your business logic in a separate, QObject based class. This way you avoid all of this mess.
