Cannot create children for a parent that is in a different thread.

在線程中new對象時添加this提示：
Cannot create children for a parent that is in a different thread.
去掉this就好了

void SocketThread::run()
{
    qDebug() << "線程1：" << QThread::currentThread();
    QTcpSocket *m_socket = new QTcpSocket(this);//錯誤
}
