 * @short_description: Window properties of a #WebKitWebView
 * @title: WebKitWindowProperties
 * @see_also: #WebKitWebView::ready-to-show
 *
 * The content of a #WebKitWebView can request to change certain
 * properties of the window containing the view. This can include the x, y position
 * of the window, the width and height but also if a toolbar,
 * scrollbar, statusbar, locationbar should be visible to the user,
 * and the request to show the #WebKitWebView fullscreen.
 *
 * The #WebKitWebView::ready-to-show signal handler is the proper place
 * to apply the initial window properties. Then you can monitor the
 * #WebKitWindowProperties by connecting to ::notify signal.
