QWebInspector не работает правильно

Я включил QWebInspector в свой проект QT и пытаюсь использовать его в своем коде (не совсем уверен, как, поскольку я все еще новичок в QT), я получаю пустой экран Web Inspector, так что я думаю, что page () возвращает ноль? Где я иду не так или это только для приложений HTML5?
