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