* 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

* `GtkWidget` types implementing the `GtkOrientable` interface will
|
||
* automatically acquire the `horizontal` or `vertical` CSS class depending on

* the value of the [property@Gtk.Orientable:orientation] property.
