/**
* gdk_screen_get_active_window
* @screen: a #GdkScreen

* Returns the screen's currently active window.

* Manager Hints</ulink>. If there is no currently currently active
* window, or the window manager does not support the
* _NET_ACTIVE_WINDOW hint, this function returns %NULL.

* On other platforms, this function may return %NULL, depending on whether
* it is implementable on that platform.
*
* The returned window should be unrefed using g_object_unref() when
* no longer needed.
