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. \sa QWebView, QGraphicsTextItem */ /*! \fn void QGraphicsWebView::loadStarted() This signal is emitted when a new load of the page is started. \sa loadProgress(), loadFinished() */ /*! \fn void QGraphicsWebView::loadFinished(bool ok) This signal is emitted when a load of the page is finished. \a ok will indicate whether the load was successful or any error occurred. \sa loadStarted() */ /*!
