{
   NOTE this widget is considered too specialized/little-used for
   GTK+, and will in the future be moved to some other package.  If
   your application needs this widget, feel free to use it, as the
   widget does work and is useful in some applications; it's just not
   of general interest. However, we are not accepting new features for
   the widget, and it will eventually move out of the GTK+
   distribution.
