QNetworkAccessManager->get problem (no matching function)

[Cucus]

I've checked lots of examples and this code is supposed connect to google.com

QNetworkAccessManager * Network_Manager;
    Network_Manager = new QNetworkAccessManager(this);
    QString URL;
    URL = "http://www.google.com/";
    QNetworkRequest netRequest(QUrl(URL));
    Network_Manager->get(netRequest);

QNetworkAccessManager * Network_Manager;
    Network_Manager = new QNetworkAccessManager(this);
    QString URL;
    URL = "http://www.google.com/";
    QNetworkRequest netRequest(QUrl(URL));
    Network_Manager->get(netRequest);

To copy to clipboard, switch view to plain text mode 

But I get this error when trying to compile:

error: no matching function for call to QNetworkAccessManager::get(QNetworkRequest (&)(QUrl))'
candidates are: QNetworkReply* QNetworkAccessManager::get(const QNetworkRequest&)

error: no matching function for call to QNetworkAccessManager::get(QNetworkRequest (&)(QUrl))'
candidates are: QNetworkReply* QNetworkAccessManager::get(const QNetworkRequest&)

To copy to clipboard, switch view to plain text mode 

I've added
#include <QNetworkAccessManager>
#include <QtNetwork>
and
QT += network in my .pro

thanks in advance...
