 102  * #GtkWidget implementing the scrolling interface which means you can
 103  * embed in a #GtkScrolledWindow. It is responsible for managing the
 104  * drawing of the content, forwarding of events. You can load any URI
 105  * into the #WebKitWebView or any kind of data string. With #WebKitWebSettings
 106  * you can control various aspects of the rendering and loading of the content.
 107  * Each #WebKitWebView has exactly one #WebKitWebFrame as main frame. A
 108  * #WebKitWebFrame can have n children.
