WebKitWindowProperties

Window properties of a #WebKitWebView.

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.

    // Get the WebKitWindowProperties of the web view and monitor it.
