Multithreaded Server

I'm writing a simple multithreaded server and I wind up with this code:

Code:

ServerThread::ServerThread(int handle, QObject* parent)
    :QThread(parent)
{
    m_descriptor = handle;
    init();
}
 
void ServerThread::run()
{
    m_socket = new QTcpSocket();
 
    if(!m_socket->setSocketDescriptor(m_descriptor))
    {
        qDebug("Socket Error!");
        exit(-1);
    }
 
    connect(m_socket, SIGNAL(readyRead()), this, SLOT(ready()),Qt::DirectConnection);
 
    m_socket->waitForReadyRead(10000);
}
 
void ServerThread::ready()
{
    disconnect(m_socket, SIGNAL(readyRead()));
 
    //Check incoming command
    if(m_socket->canReadLine())
    {
        QStringList tokens = QString(m_socket->readLine()).split(QRegExp("[\r\n][\r\n]*"));
 
        switch(map.value(tokens[0]))
        {
        case GETA:
            doSomeThing();
            break;
        case GETB:
            doSomeThing();
            break;
        case QUIT:
            m_socket->disconnectFromHost();
            break;
        default:
            m_socket->disconnectFromHost();
            return;
        }
    }
}

The above code works, but is it a good way to do it ?
