QObject :: connect没有启动Tcp信号

Question

让我的QObject连接到tcp启动时遇到问题.. 任何建议请和你的时间相比

似乎开始永远不会被称为......

mainwindow.cpp

void MainWindow::on_pushButton_3_clicked()
{
      LoginServer tcpServer;
      QObject::connect(&tcpServer, SIGNAL(tcpServer::stopped()), this, SLOT(tcpServer::start(port)));
}

loginserver.h

signals:
    void stopped();
public slots:
    void start(quint16 port);
    void stop();
private slots:
    void threadStarted();
    void threadFinished();
protected:
    void incomingConnection(qintptr) Q_DECL_OVERRIDE;
private:
    QAtomicInt activeSessions;
    QSemaphore threadWaitSemaphore;

Loginserver.cpp

void LoginServer::start(quint16 port)
{
    // Start the Login server
    // QHostAddress::Any
    //QHostAddress::LocalHost
    if (!listen(QHostAddress::Any, port))
    {
        QString Login_Server_Error = QStringLiteral("Couldn't start the login server");
        ui->textBrowser->append(Login_Server_Error);
        return;
    }
    else
    {
        QString Login_Server_Connection = QStringLiteral("Login Server Started on port: %1").arg(port);
        ui->textBrowser->append(Login_Server_Connection);
    }
}
