Detailed Description

The QChildEvent class contains event parameters for child object events.

Child events are sent to objects when children are inserted or removed.

A ChildRemoved event is sent immediately, but a ChildInserted event is posted (with QApplication::postEvent()).

The handler for these events is QObject::childEvent().
