void MainWindow::on_ParceButton_clicked()
{
    ui->ParceButton->setEnabled(false);
    int thr = ui->lineEdit4->text().toInt();
    ifstream inp_tmp("AllTempLinks.txt");
    runnedth=0;

    QNetworkAccessManager *nmanager = new QNetworkAccessManager;
    connect(nmanager, SIGNAL(finished(QNetworkReply*)), this, SLOT(FinishedSlot(QNetworkReply*)));
    string link;
    while(getline(inp_tmp,link))
    {
        QUrl req = QUrl(QString::fromStdString(link));

        while(runnedth >= thr)
        {
            QApplication::processEvents();
        }

        QNetworkReply* reply = nmanager->get(QNetworkRequest(req));
        ui->label_6->setNum(totalglinks);
    }


    inp_tmp.close();
    ui->ParceButton->setEnabled(true);
}

所有请求都成功结束,但是 ui->label_6->setNum(totalglinks); 不工作。当我的函数被调用时,ParceButton 仍然处于活动状态。
