qmake and webkit problem

This happens with examples, demos, tutorials or roll your own.

qmake always generates this: webView->setUrl(QUrl("about:blank"));

and then rejects it here: error: ‘class QWebView’ has no member named ‘setUrl’

I have searched all over, no one else seems to have this problem.

Using Creator 4.5.2

Thanks in advance.

I understand this may be a stupid question, but I sure would appreciate a nudge in the right direction here.
