This class can be used, together with QWebFrame, to provide functionality like QWebView in a widget-less environment. QWebPage's API is very similar to QWebView, as you are still provided with common functions like action() (known as \l{QWebView::}{pageAction()} in QWebView), triggerAction(), findText() and settings(). More QWebView-like functions can be found in the main frame of QWebPage, obtained via QWebPage::mainFrame(). For example, the load(), setUrl() and setHtml() unctions for QWebPage can be accessed using QWebFrame. The loadStarted() signal is emitted when the page begins to load.The loadProgress() signal, on the other hand, is emitted whenever an element of the web page completes loading, such as an embedded image, a script, etc. Finally, the loadFinished() signal is emitted when the page has loaded completely. Its argument, either true or false, indicates whether or not the load operation succeeded. \section1 Using QWebPage in a Widget-less Environment Before you begin painting a QWebPage object, you need to set the size of the viewport by calling setViewportSize(). Then, you invoke the main frame's render function (QWebFrame::render()). An example of this is shown in the code snippet below. Suppose we have a \c Thumbnail class as follows: \snippet webkitsnippets/webpage/main.cpp 0 The \c Thumbnail's constructor takes in a \a url. We connect our QWebPage object's \l{QWebPage::}{loadFinished()} signal to our private slot, \c render(). \snippet webkitsnippets/webpage/main.cpp 1 The \c render() function shows how we can paint a thumbnail using a QWebPage object. \snippet webkitsnippets/webpage/main.cpp 2 We begin by setting the \l{QWebPage::viewportSize()}{viewportSize} and then we instantiate a QImage object, \c image, with the same size as our \l{QWebPage::viewportSize()}{viewportSize}. This image is then sent as a parameter to \c painter. Next, we render the contents of the main frame and its subframes into \c painter. Finally, we save the scaled image. \sa QWebFrame */ /*!
