gtk:status-icon-visible (object)

object -- a gtk:status-icon widget
visible -- true to show the status icon, false to hide it

Accessor of the visible slot of the gtk:status-icon class. The gtk:status-icon-visible function returns whether the status icon is visible or not. The (setf gtk:status-icon-visible) functon sets the visibility.

Note that being visible does not guarantee that the user can actually see the icon, see also the gtk:status-icon-is-embedded function. The gtk:status-icon-visible function has been deprecated since version 3.14 and should not be used in newly written code.
