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()).
Note that if a child is removed immediately after it is inserted, the ChildInserted event may be suppressed, but the ChildRemoved event will always be sent. In this case there will be a ChildRemoved event without a corresponding ChildInserted event.
The handler for these events is QObject::childEvent().
See also Event Classes.
