Problem with QHttp / HTML source download

[hojoff79]

I am trying to download html source code from a website given in a line edit bar. The code for the function which does so appears below. Everything seems to work fine except i get an error "incomplete type 'QUrl' used in nested name specifier. Which I think is kind of weird since I copied this example directly out of the source documentation.

void MainWindow::gethtml(){
    QString address = ui->lineEdit->text();
    ui->textEdit->setText(address);
    http = new QHttp;
    QHttpRequestHeader header("GET", QUrl::toPercentEncoding("/index.html"));
    header.setValue("Host", "qt.nokia.com");
    http->setHost("qt.nokia.com");
    http->request(header);
 
}

void MainWindow::gethtml(){
    QString address = ui->lineEdit->text();
    ui->textEdit->setText(address);
    http = new QHttp;
    QHttpRequestHeader header("GET", QUrl::toPercentEncoding("/index.html"));
    header.setValue("Host", "qt.nokia.com");
    http->setHost("qt.nokia.com");
    http->request(header);

}

Thank you in advance!
