Qt在多线程中使用QTcpSocket碰见的有关问题

Qt在多线程中使用QTcpSocket碰见的问题
在Qt中写多线程网络通信时碰到了个问题，具体情形如下：
新建一个FileRecvThread继承QThread,重写run函数

C/C++ code


class FileRecvThread : public QThread
{
    Q_OBJECT
public:
    explicit FileRecvThread(QObject *parent = 0);
    FileRecvThread(quint32, QObject *parent = 0);
    ~FileRecvThread();

    void initSignalSlots();

    void setPort(quint32 port);
    quint32 getPort();
 
    void dealShackHand(QByteArray *);
    void replyExpectShackHand();

protected:
    void run();

private:
    quint32 port;
    QTcpServer *pTcpServer;
    QTcpSocket *pTcpSocket;

public slots:
    void startTcpServer();
    void dealNewConnection();
    void dealDatagram();

FileRecvThread::FileRecvThread(quint32 port, QObject *parent) :
    QThread(parent)
{
    this->port = port;
}

void FileRecvThread::startTcpServer()
{
    if (!this->pTcpServer)
    {
        this->pTcpServer = new QTcpServer;
        this->pTcpServer->listen(QHostAddress::Any, this->port);
    }
    else
    {
        this->pTcpServer->listen(QHostAddress::Any, this->port);
    }
}

void FileRecvThread::run()
{
    this->startTcpServer();
    this->initSignalSlots();
    this->exec();

}
void FileRecvThread::initSignalSlots()
{
    connect(this->pTcpServer, SIGNAL(newConnection()), this, SLOT(dealNewConnection()));
}

void FileRecvThread::dealNewConnection()
{
    this->pTcpSocket = this->pTcpServer->nextPendingConnection();
    connect(this->pTcpSocket, SIGNAL(readyRead()), this, SLOT(dealDatagram()));
}

void FileRecvThread::dealDatagram()
{
    QByteArray byteArray = this->pTcpSocket->readAll();
    //这里出现问题
    [color=#FF0000]this->pTcpSocket->write(QByteArray("deal"));[/color]
}

原来写过java所以this用的比较多，大家见谅-。-！
把代码裁剪了下，一些不需要贴出来的都删掉了，具体问题如下：
在Qt creator下出现
QObject: Cannot create children for a parent that is in a different thread.
(Parent is QNativeSocketEngine(0xac00878), parent's thread is FileRecvThread(0xac131b8), current thread is QThread(0x3e54c8)，
意思我明白，就是对象不在同一线程下新建和调用出现的问题，可是
QTcpSocket作为FileRecvThread的子对象存在，而且用qDebug打印了下
pTcpSocket->thread()和pTcpServer->thread()这是一致的，都是0x3e54c8,
this->pTcpSocket->write("deal");也是在FileRecvThread内，按道理说他是属于FileRecvThread线程的，何况先使用了this->pTcpSocket->readAll();
能读取数据，而this->pTcpSocket->write();却不行，这是什么原因，求解
。。。。。
谢谢大虾了~~~

------解决方案--------------------
connect后执行的槽函数并不是在你的run函数所处的线程中执行的
每次有信号其实都在主线程中执行，而你的QTcpSocket初始化是在run的线程中
不知道是不是这个原因
