Event for Layer visibility changed?

[FalkoWieland]

In my Widget it is necessary to handle changed visibility of Layers. Is there a event witch raises when the visibility of a Layer changed due to MapSwitchWidget or LayerListWidget and how to catch it?

Thanks a lot in advance

In my widget i used

map.addEventListener(PanEvent.PAN_END,panEventListener);

to catch a pan of the map, but cannot find a event for changed visibility.

See com.esri.viewer.components.toc.tocClasses.TocMapLayerItem for an example where it's listening to FlexEvent.SHOW and FlexEvent.HIDE.
