LayerList widget list to order changes

Aeseir

When setting up LayerList widget I've set selectionEnabled to true, which allows the layers to be reordered including placing layers as sublayers.

 

What i want to be able to do is listen for any event that will tell me the order/hierarchy has changed and what the new structure looks like.

 

There is no documentation explaining if there is a event to even listen for.

Just to add on on the answer that was provided by @Sage_Wall, you can also add reactiveUtils to all the operationalLayers of the LayerList widget. You can maybe store the initial arrange of the layers somewhere and compare every time it changes. The function below will list down all the layers ID  when operational layers are modified.

reactiveUtils.watch(
          () => layerList.operationalItems.map(item => item.layer.id),
          (ids) => {
            console.log(`FeatureLayer IDs ${ids}`);
          });
