* SECTION:gtkorientable
* @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.
