This one is a little tricky, since we override this property in many places, and you cannot add flags when overriding. So, all places where this is overridden will have to make sure to notify explicitly.

|
||
* @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.
