+ * @Short_description: An interface for flippable widgets
+ * @Title: GtkOrientable
+ *
+ * The #GtkOrientable interface is implemented by all widgets that can be
+ * oriented horizontally or vertically. Historically, such widgets have been
+ * realized as subclasses of a common base class (e.g #GtkBox/#GtkHBox/#GtkVBox
+ * or #GtkScale/#GtkHScale/#GtkVScale). #GtkOrientable is more flexible in that
+ * it allows the orientation to be changed at runtime, allowing the widgets
+ * to 'flip'.
+ *
+ * #GtkOrientable was introduced in GTK+ 2.16.
