Answer 1

QNewtorkRequest takes a QUrl object in its constructor. You can use :

QNetworkRequest* request = new QNetworkRequest(QUrl("http://en.wikipedia.org/wiki/Cars"));

Check out Qt's doc if you want to check out which arguments are taken into constructors. If you use QtCreator, the doc is embedded and it usually will inform you of the possible types you can give to functions as parameters.

Answer 2

QUrl wikiUrl("http://en.wikipedia.org/wiki/Cars");
QNetworkRequest* request = new QNetworkRequest(wikiUrl);

The above should work.
