* @short_description: The central class of the WebKitGTK+ API
* @see_also: #WebKitWebSettings, #WebKitWebFrame
*
* #WebKitWebView is the central class of the WebKitGTK+ API. It is a
* #GtkWidget implementing the scrolling interface which means you can
* embed in a #GtkScrolledWindow. It is responsible for managing the
* drawing of the content, forwarding of events. You can load any URI
* into the #WebKitWebView or any kind of data string. With #WebKitWebSettings
* you can control various aspects of the rendering and loading of the content.
* Each #WebKitWebView has exactly one #WebKitWebFrame as main frame. A
* #WebKitWebFrame can have n children.
*
* <programlisting>
* /<!-- -->* Create the widgets *<!-- -->/
