Determine whether the network is connected

fanxinglanyu

This is my code.But I have a problem. When the Internet is disconnected, it will show that the Internet is not disconnected for 1 minute.Thanks,I need your help.

    QHostInfo::lookupHost("www.baidu.com", this, &MainWindow::netWorkStatus);
bool MainWindow::netWorkStatus(const QHostInfo& host)
{

    if (host.error() != QHostInfo::NoError) {
        qDebug() << "Lookup failed:" << host.errorString();
        ui->label_2->setText("Broken network");
        return false;
    }else{

        qDebug()<<"";
        ui->label_2->setText("Connected to the Internet");

       // QHostInfo::abortHostLookup(lookupID);

        return true;
    }
}
