    \class QGraphicsWebView
    \brief The QGraphicsWebView class allows Web content to be added to a GraphicsView.
    \since 4.6

    An instance of this class renders Web content from a URL or supplied as data, using
    features of the QtWebKit module.

    If the width and height of the item is not set, they will dynamically adjust to
    a size appropriate for the content. This width may be large (e.g., 980 pixels or
    more) for typical online Web pages.

    \section1 Browser Features

    Many of the functions, signals and properties provided by QWebView are also available
    for this item, making it simple to adapt existing code to use QGraphicsWebView instead
    of QWebView.

    The item uses a QWebPage object to perform the rendering of Web content, and this can
    be obtained with the page() function, enabling the document itself to be accessed and
    modified.

    As with QWebView, the item records the browsing history using a QWebHistory object,
    accessible using the history() function. The QWebSettings object that defines the
    configuration of the browser can be obtained with the settings() function, enabling
    features like plugin support to be customized for each item.
