It can be used in various applications to display web content live from the Internet. The image below shows QWebView previewed in \QD with a Nokia website. \image qwebview-url.png A web site can be loaded onto QWebView with the load() function. Like all Qt widgets, the show() function must be invoked in order to display QWebView. The snippet below illustrates this: \snippet webkitsnippets/simple/main.cpp Using QWebView Alternatively, setUrl() can also be used to load a web site. If you have the HTML content readily available, you can use setHtml() instead. The loadStarted() signal is emitted when the view begins loading. The loadProgress() signal, on the other hand, is emitted whenever an element of the web view completes loading, such as an embedded image, a script, etc. Finally, the loadFinished() signal is emitted when the view has loaded completely. It's argument - either \c true or \c false - indicates load success or failure. The page() function returns a pointer to the web page object. See \l{Elements of QWebView} for an explanation of how the web page is related to the view. To modify your web view's settings, you can access the QWebSettings object with the settings() function. With QWebSettings, you can change the default fonts, enable or disable features such as JavaScript and plugins. The title of an HTML document can be accessed with the title() property. Additionally, a web site may also specify an icon, which can be accessed using the icon() property. If the title or the icon changes, the corresponding titleChanged() and iconChanged() signals will be emitted. The textSizeMultiplier() property can be used to change the overall size of the text displayed in the web view. If you require a custom context menu, you can implement it by reimplementing \l{QWidget::}{contextMenuEvent()} and populating your QMenu with the actions obtained from pageAction(). More functionality such as reloading the view, copying selected text to the clipboard, or pasting into the view, is also encapsulated within the QAction objects returned by pageAction(). These actions can be programmatically triggered using triggerPageAction(). Alternatively, the actions can be added to a toolbar or a menu directly. QWebView maintains the state of the returned actions but allows modification of action properties such as \l{QAction::}{text} or \l{QAction::}{icon}. A QWebView can be printed onto a QPrinter using the print() function. This function is marked as a slot and can be conveniently connected to \l{QPrintPreviewDialog}'s \l{QPrintPreviewDialog::}{paintRequested()} signal. If you want to provide support for web sites that allow the user to open new windows, such as pop-up windows, you can subclass QWebView and reimplement the createWindow() function. \section1 Elements of QWebView QWebView consists of other objects such as QWebFrame and QWebPage. The flowchart below shows these elements are related. \image qwebview-diagram.png \note It is possible to use QWebPage and QWebFrame, without using QWebView, if you do not require QWidget attributes. Nevertheless, QtWebKit depends on QtGui, so you should use a QApplication instead of QCoreApplication. \sa {Previewer Example}, {Web Browser}, {Form Extractor Example}, {Google Chat Example}, {Fancy Browser Example} */ /*!
