socket notifiers cannot be enabled from another thread

用QTcpSocket实现的客户端.
要求：
1，有一个线程不停的等待接收这个socket的数据(有数据一到,就接收,然后写入一个全局变量（QString）中).
2, 要求主线程,可以对这个socket发送数据.

我自己写,老是出现socket notifiers cannot be enabled from another thread.
class SocketThread : public QThread {     Q_OBJECT public:     explicit SocketThread(QObject *parent = 0): QThread(parent) {} public:     void run() 毕业论文 {         m_pClient = new QTcpSocket();         m_pClient->connectToHost("127.0.0.1", 8866);         if (m_pClient->waitForConnected(5000)) {             qDebug() << "sokcet thread connected";             //sendData("GetMember");         }         QThread::exec();     }   public slots:     void  recvData() {         QByteArray arr = m_pClient->readAll();         QString recvStr(arr);         qDebug() << "socket thread::recvData: " << recvStr;           gRecvDataStr.append(recvStr);     }     void  sendData(QString sendStr) { m_pClient->write(sendStr.toStdString().c_str()); } public:     QTcpSocket *m_pClient; };

 //调用     SocketThread *p = new SocketThread();     p->start();     Sleep(300);     p->sendData("GetMember");

试下 movetothread
