WebKit in Qt

Architecture

The easiest way to render content is through the QWebView class. As a widget it can be embedded into your forms or a graphics view, and it provides convenience functions for downloading and rendering web sites.

     QWebView *view = new QWebView(parent);
     view->load(QUrl("http://qt.nokia.com/"));
     view->show();

QWebView is used to view Web pages. An instance of QWebView has one QWebPage. QWebPage provides access to the document structure in a page, describing features such as frames, the navigation history, and the undo/redo stack for editable content.

HTML documents can be nested using frames in a frameset. An individual frame in HTML is represented using the QWebFrame class. This class includes the bridge to the JavaScript window object and can be painted using QPainter. Each QWebPage has one QWebFrame object as its main frame, and the main frame may contain many child frames.

Individual elements of an HTML document can be accessed via DOM JavaScript interfaces from within a web page. The equivalent of this API in QtWebKit is represented by QWebElement. QWebElement objects are obtained using QWebFrame's findAllElements() and findFirstElement() functions with CSS selector queries.

Common web browser features, defaults and other settings can be configured through the QWebSettings class. It is possible to provide defaults for all QWebPage instances through the default settings. Individual attributes can be overidden by the page specific settings object.
