[OpenLayers-Users] layer.visibility = true doesn't add checkbox

[Vidal, Antoni]

Hello list,

 

I would like to show an overlay, only when baselayer is aerial photo, not over baselayer topographic map. 

 

My code:

 

map.events.register("changebaselayer", map, function(){

                var tpnorto = map.getLayersByName("topoorto")[0];

                if(map.baseLayer.name == 'Topographic'){

                               tpnorto.visibility = "false";

                }else tpnorto.visibility = "true";

});

 

I get visibility change ok, but checkbox next to overlay name (in layerswitcher) are not showned and I wold like to check and uncheck this layer to allow user to try if overlay is visible or not when they select aerial map.

 

Any suggestion?

 

Thank's in advance.
