The QWebPage::ErrorPageExtensionReturn describes the error page, which will be shown for the frame for which the error occurred.

The QWebPage::ErrorPageExtensionReturn class holds the data needed for creating an error page. Some are optional such as contentType, which defaults to "text/html", as well as the encoding, which is assumed to be UTF-8 if not indicated otherwise.

The error page is stored in the content byte array, as HTML content. In order to convert a QString to a byte array, the QString::toUtf8() method can be used.

External objects such as stylesheets or images referenced in the HTML are located relative to baseUrl.
