Invalid conversion error while Storing into Combobox

[owais_blore]

Hi I am bit new to QT programming. I am working on server proxy related module where I need to store the result into the combobox. Here goes the example:

QNetworkProxyQuery npq(QUrl(QLatin1String("http://www.google.com")));
    QList<QNetworkProxy> listOfProxies = QNetworkProxyFactory::systemProxyForQuery(npq);
 
    foreach ( QNetworkProxy loopItem, listOfProxies )
    {
           qDebug() << "ProxyHostName_IP: " << loopItem.hostName();
           qDebug()<< "Port: " << loopItem.port();
 
           ui->comb_conf_box->addItem(loopItem.hostName()); //combo box for Host name IP
           ui->comb_port_box->addItem(loopItem.port()); // combo box for POrt
   }

QNetworkProxyQuery npq(QUrl(QLatin1String("http://www.google.com")));
    QList<QNetworkProxy> listOfProxies = QNetworkProxyFactory::systemProxyForQuery(npq);

    foreach ( QNetworkProxy loopItem, listOfProxies )
    {
           qDebug() << "ProxyHostName_IP: " << loopItem.hostName();
           qDebug()<< "Port: " << loopItem.port();

           ui->comb_conf_box->addItem(loopItem.hostName()); //combo box for Host name IP
           ui->comb_port_box->addItem(loopItem.port()); // combo box for POrt
   }

To copy to clipboard, switch view to plain text mode 

I am able to receive Host Name IP but Port number doesnt appear. Please help!!!

Eroor thrown is: Invalid conversion from quint16 to const char*

ui->comb_port_box->addItem( QString::number( loopItem.port() ) ); // combo box for POrt

ui->comb_port_box->addItem( QString::number( loopItem.port() ) ); // combo box for POrt
