In this case there will be a <a href="qevent.html#Type-enum">ChildRemoved</a> event without a corresponding <a href="qevent.html#Type-enum">ChildInserted</a> event. <p> The handler for these events is <a href="qobject.html#childEvent">QObject::childEvent</a>(). <p>See also <a href="events.html">Event Classes</a>. <hr><h2>Member Function Documentation</h2> <h3 class=fn><a name="QChildEvent"></a>QChildEvent::QChildEvent ( <a href="qevent.html#Type-enum">Type</a> type, <a href="qobject.html">QObject</a> * child ) </h3> <p> Constructs a child event object.
