## Detailed Description

An introduction to the QtWebKit module.

To import the module use, for example, the following statement:

    from PyQt4 import QtWebKit

QtWebKit provides a Web browser engine that makes it easy to embed content from the World Wide Web into your Qt application. At the same time Web content can be enhanced with native controls.

QtWebKit provides facilities for rendering of HyperText Markup Language (HTML), Extensible HyperText Markup Language (XHTML) and Scalable Vector Graphics (SVG) documents, styled using Cascading Style Sheets (CSS) and scripted with JavaScript.

A bridge between the JavaScript execution environment and the Qt object model makes it possible for custom QObjects to be scripted. Integration with the Qt networking module enables Web pages to be transparently loaded from Web servers, the local file system or even the Qt resource system.

In addition to providing pure rendering features, HTML documents can be made fully editable to the user through the use of the `contenteditable` attribute on HTML elements.

QtWebKit is based on the Open Source WebKit engine. More information about WebKit itself can be found on the WebKit Open Source Project Web site.

The QtWebKit module is part of the Qt Desktop Edition, and the Qt Open Source Edition.

### 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://www.trolltech.com/"));
         view->show();

QWebView acts as a view onto Web pages, each of which is represented by an instance of the QWebPage class. 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. It includes the bridge to the JavaScript window object and can be painted using QPainter. Each QWebPage has one QWebFrame object as its main frame.

Individual 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.
