Detailed Description
Child window events are sent to windows when children are added or removed.
In both cases you can only rely on the child being a QWindow — not any subclass thereof. This is because in the QEvent::ChildWindowAdded case the subclass is not yet fully constructed, and in the QEvent::ChildWindowRemoved case it might have already been destructed.
