Detailed Description

Wraps any QWidget* (or QObject*) as an IView.

Lifetime (L-32)

The wrapped QObject is owned by Qt's parent-child tree, not by us. We connect to QObject::destroyed and fire the IView destroy signal from there — i.e. while this subclass's state is still valid, which is what the adapter contract asks for. Relying on the ~IView fallback alone would be too late (and never happen at all for a QtView that is kept alive by a cache).

QPointer additionally keeps object() safe if the widget is destroyed before anyone notices.
