Hi,

How can I show/hide the layer comparison tool with a button? I want it to be inactive by default, but users should be able to activate it if they want to.

In the app config I found the parameter ‘layerComparisonIsActive’, but I can't think of a way to change this on the fly. Does anyone know how to achieve this?

Thanks in advance.

  With the layer-comparison.set-mode command

  https://developers.vertigisstudio.com/docs/web/api-commands-operations/#command-layer-comparison.set-mode

  [
     {
         "name": "layer-comparison.set-mode",
         "arguments": {
             "active": true
         }
     }
  ]

  See the 'Lagen' and ‘Verberg slider’ buttons on the 'Gegevens' tab in the toolbar in this viewer https://geoweb.rijkswaterstaat.nl/ModuleViewer/?app=c70700cd9e7a49debd31b05d05ebdac1

  Ahh, thanks once again Nico! I scanned all the commands, but ‘set-mode’ didn't trigger me, didn't sound like an ‘activate’ command. More carefull reading next time..

  Hi Yannick;
  
  you can achieve this with the following command: layer-comparison.set-mode

  Here is an example in which some properties are also set:

  1. Set the desired basemap
  2. Switch on layer-comparision mode
  3. Incluse a leading layer

  4. Set the visibility of a layer

     [
      {
        "name": "basemap.set",
        "arguments": {
          "basemap": "item://basemap-extension/43a92a76-f6c5-4da8-927a-ee1f3e810a14"
        }
      },
      {
        "name": "layer-comparison.set-mode",
        "arguments": {
          "active": true
        }
      },
      {
        "name": "layer-comparison.add-leading-layers",
        "arguments": "My Satellite Layer"
      },
      {
        "name": "layers.set-visibility",
        "arguments": {
          "layers": "My Satellite Layer",
          "visible": true
        }
      }
     ]
