Actually, I'm also seeing QNSWindows (even the occasional QNSPanel). I'm not
perfectly sure if I've ever seen instances of those because of a WId I
received;
can you be that all WIds are always and exclusively of the (Q)NSView persuasion?

internalWinId() is defined as `inline WId internalWinId() const { return data-
>winid; }` in the QWidget class definition, so I doubt that calling the

will have a lot of side-effects if no winid was created yet ;)
Either way, calling a method to obtain the WId from an object that is bound to
have such a property helps me only if I can do it in a function that is called
each time such an object is created. That's what I was really asking about: how
to get notified each time something is created that has a WId.
Alternatively I could work with a notification when a new window (NSWindow) is
created or one is closed, and then parse the entire list of windows with their
NSView and sub-NSViews (or their superView and that critter's subviews).
I've tried googling, but until now I've only come up with searches that give
way
too many irrelevant hits.
