gtk-action-visible-horizontal (object)

object -- a gtk-action object
visible -- true to make the action visible horizontally

Accessor of the visible-horizontal slot of the gtk-action class.

The slot access function gtk-action-visible-horizontal checks whether the action is visible when horizontal. The slot access function (setf gtk-action-visible-horizontal) sets the visibility. The function gtk-action-visible-horizontal has been deprecated since version 3.10 and should not be used in newly written code.
