[OpenLayers-Users] VisibilityChanged event handler

[Dmitri Mizerkin]

Hello List,

I am using layer pairs in my map, one of those for selection. I would like
to remove the selection layer from the map as soon as the user removes the
main layer using the layer switcher. Is it possible to register some
"visibilityChanged" event handler, so that it calls a function as soon as
its visibility parameter changes?
It could be something like that:

layer.events.register("visibilityChanged", layer, function(e) {} );

Maybe there is some way to register the event in the layer switcher control
as well, which could call the function as soon as it has changes?

Thanks in advance!
Dmitri
