Get current ip address

[Trok]

Hi, I have problem with ip address.
How can i get current ip address on my pc? I tried used this code:

QHostInfo info;
    QNetworkInterface ifObj = QNetworkInterface::interfaceFromName(info.hostName());
    qDebug() << ifObj;

QHostInfo info;
    QNetworkInterface ifObj = QNetworkInterface::interfaceFromName(info.hostName());
    qDebug() << ifObj;

To copy to clipboard, switch view to plain text mode 

It was returned:

QNetworkInterface( name = "", hardware address = "", flags = , entrise = () )

QNetworkInterface( name = "", hardware address = "", flags = , entrise = () )

To copy to clipboard, switch view to plain text mode 

also I used function: QNetworkAddressEntry::ip () , but without results.

So, I wait for yours propositions to solve my problem.
