* @Short_description: An interface for flippable widgets
|
||
* @Title: GtkOrientable
|
||
*
|
||
* The #GtkOrientable interface is implemented by all widgets that can be
|
||
* oriented horizontally or vertically. #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.
