Hi,
setOpacity calls the map changelayer event. When this event is called,
the layer changed is passed.
So you could add a listener on this event and check which layer was
changed and act accordingly.
Here's the code that trigger the event (from Layer.js):
this.map.events.triggerEvent("changelayer", {
layer: this,
property: "opacity"
});
Best regards,
Julien

Hi,
When a layer's opacity is changed, I would like to assign the new
opacity to another layer. I found the map event layerchange, but is
there an event on the layer? That would be easier to use to me.
I'm using geoext slider to change the opacity
thanks
steve
