89  *
90  * #WebKitWebView is the central class of the WebKitGTK+ API. It is a
91  * #GtkWidget implementing the scrolling interface which means you can
92  * embed in a #GtkScrolledWindow. It is responsible for managing the
93  * drawing of the content, forwarding of events. You can load any URI
94  * into the #WebKitWebView or any kind of data string. With #WebKitWebSettings
95  * you can control various aspects of the rendering and loading of the content.
96  * Each #WebKitWebView has exactly one #WebKitWebFrame as main frame. A
97  * #WebKitWebFrame can have n children.
