handle/listen Layer visibility events

davizuco666

I need to listen to layer visibility changes, but can´t figure out how to do it with Javascript 4.x SDK.

LayerList "trigger-action" never triggers on layer visibility changes.

I Tryed like:LayerList.on

But just working on "load" event..

 

Also triyed to see all events to find the right one, with no success.

 

Any ideas?

Auto awnser:

layer.watch('visible', (visibility, a, eventName,layer) => {
                console.log("visible: ", visibility);
                console.log(layer, eventName, a);
            });

 

I don't understand why there is no mention of this in the documentation, watch is not even in the list of methods.

You just have to guess...
