比如，想获得socket的状态枚举文字，

代码如下：

QMetaObject mo=QAbstractSocket::staticMetaObject;    int index=mo.indexOfEnumerator(QString("SocketState").toLatin1().data());    QMetaEnum socketStatusEnum = mo.enumerator(index);    qDebug()<

输出为：

Starting F:\exercise\build-untitled19-Desktop_Qt_5_4_0_MinGW_32bit-Debug\debug\untitled19.exe...7UnconnectedStateHostLookupStateConnectingStateConnectedStateBoundStateListeningStateClosingState

当想要输出当前socket的状态的时候，可以看下面代码

QTcpSocket *socket=new QTcpSocket;    QAbstractSocket::SocketState socketState=socket->state();    const QMetaObject & mo = QAbstractSocket::staticMetaObject;    QMetaEnum me = mo.enumerator(mo.indexOfEnumerator("SocketState"));    qDebug()<

输出为

Starting F:\exercise\build-untitled10-Desktop_Qt_5_4_0_MinGW_32bit-Debug\debug\untitled10.exe...UnconnectedState
