[OpenLayers-Users] Adjusting layers when other layers are active(layer switcher)

[Arnd Wippermann]

Try it with 

map.events.register("changelayer", map, yourFunction });

Or 

map.layers[3].events.register('visibilitychanged', map.layers[3],
yourFunction });

Betreff: [OpenLayers-Users] Adjusting layers when other layers are
active(layer switcher)


I am running OL2.5 and have a requirement to adjust the visibility or
transparency of certain layers depending on whether or not a certain layer
is selected in the LayerSwitcher.  For example I have the base layer and
layers 1,2 and 3.  Layers 1 and 2 are visible when the page loads, 3 is not.
When layer 3 is selected in the LayerSwitcher then layer 1 should be not
visible (and deselected in the LayerSwitcher) and layer 2 should have the
transparency set to .40.  If layer 3 is deselected then layer 1 should then
be selected and visible with layer 2's transparency reset to 1.0.  Any help
in doing all that would be greatly appreciated.
