|QObject *||child() const|
Child events are sent immediately to objects when children are added or removed.
In both cases you can only rely on the child being a QObject (or, if QObject::isWidgetType() returns
true, a QWidget). This is because in the QEvent::ChildAdded case the child is not yet fully constructed; in the QEvent::ChildRemoved case it might have already been destructed.
The handler for these events is QObject::childEvent().
