 * @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 *<!-- -->/
 * GtkWidget *main_window = gtk_window_new (GTK_WINDOW_TOPLEVEL);
 * GtkWidget *scrolled_window = gtk_scrolled_window_new (NULL, NULL);
 * GtkWidget *web_view = webkit_web_view_new ();
