gtk:activatable-use-action-appearance (object)

activatable -- a gtk:activatable widget
use-appearance -- a boolean whether to use the actions appearance

The accessor for the use-action-appearance slot of the gtk:activatable class gets or sets whether the activatable should reset its layout and appearance when setting the related action or when the action changes appearance. The gtk:activatable-use-action-appearance function has been deprecated since version 3.10 and should not be used in newly written code.
