Ah, yes, damn, I forgot that : there are still problems with subclassing =
the=20
Qt::Application class (some hacks made it a bit special).
I'll have a look and see if I can fix it before the release.
However, for normal applications, and unless you really have a need to=20
reimplement some Qt::Application virtuals, it is not recommended to subcl=
as=20
it.... better subclass the MainWindow class for instance, since that woul=
d be=20
the real logical core of your app.
