QtWebView iOS C++

[whitecastleroad]

I am struggling to make a QtWebView be visible (or properly positioned?) in iOS (via the simulator). I am using the Tech Preview of the new QtWebView (using QT += webview_private). Following is my main.cpp code:

QApplication a(argc, argv);
    MainWindow w;
    w.show();

Here is my mainwindow.cpp code:

QWebView* view = new QWebView(this);
    view->setParentView(this);
    view->setGeometry(QRect(0,0,300,300));
    view->setVisible(true);
    view->setVisibility(QWindow::Visibility::Maximized);
    view->setUrl(QUrl("http://www.google.com"));

No matter what, the screen on the iOS simulator is blank. To further confuse things, the documentation states that a QWebView (maybe not the same as the new QtWebView?) is derived from QWidget, which is false. Thus, using standard QLayout and/or setCentralWidget is not an option. How do I show this thing?
