gtk-action-is-important (object)

object -- a gtk-action object
is-important -- true to make the action important

Accessor of the is-important slot of the gtk-action class.

The slot access function gtk-action-is-important checks whether the action is important or not. The slot access function (setf gtk-action-is-important) sets whether the action is important. This attribute is used primarily by toolbar items to decide whether to show a label or not. When true, toolitem proxies for this action show text in :both-horiz mode. The function gtk-action-is-important has been deprecated since version 3.10 and should not be used in newly written code.
