gtk:widget-visible (object)

object -- a gtk:widget object
setting -- a boolean whether widget is visible

Accessor of the visible slot of the gtk:widget class. The gtk:widget-visible function determines whether the widget is visible. The (setf gtk:widget-visible) function sets the visibility state. Note that this does not take into account whether the parent of the widget is also visible or the widget is obscured in any way.

If you want to take into account whether the parent of the widget is also marked as visible, use the gtk:widget-is-visible function.
