It feels slightly wrong to have GtkOrientable operate on widgets, but at least what happens when an orientable widget changes orientation should be part of GtkWidget. This will allow to add more state changes without accessing widget state from the outside of gtkwidget.c.

* @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.
