Gtk.Widget.prototype.set_visible

function set_visible(visible:Boolean):void {
    // Gjs wrapper for gtk_widget_set_visible()
}

Sets the visibility state of widget. Note that setting this to true doesn't mean the widget is actually viewable, see Gtk.Widget.prototype.get_visible.

This function simply calls Gtk.show or Gtk.Widget.prototype.hide but is nicer to use when the visibility of the widget depends on some condition.
