[GeoNetwork-users] Adding an ol3 Layer to the LayerManager

Sebastian_Hubner · August 3, 2015, 1:44pm

Hi list,

in my GN3 catalog the user can add various layers to the map by calling map.addLayer() function from the OpenLayers3 library.
Anyway, the new layer is displayed correct and I'd like to have the newly added layer to be displayed in the 'Manage Layers' overlay where the user can hide or show layers.

I guess that the LayerManager is populated by an array returned from map.getLayers().getArray(), as written in the LayerManagerDirective.js on line 74. The newly added layer is present when I call this function ( map.getLayers().getArray() ) in my code after the layer was added to the map. So the map has recognized the added layer.

So my question is: Is there a way to somehow force the LayerManager to refresh whenever a layer has been added to the map, just as when you add a layer via the 'Add Layer' overlay? Or has the layer to be some kind of a wms layer in order to be displayed in the LayerManager?

Kind regards,

Sebastian

Hi,

The layermanager is bound to the map layers collection, but it is filtered.
https://github.com/geonetwork/core-geonetwork/blob/develop/web-ui/src/main/resources/catalog/components/viewer/layermanager/partials/layermanager.html#L2

The filter function is in

github.com

geonetwork/core-geonetwork/blob/f2e313e4fe57c60af4b5ab25c1edf493c26e659c/web-ui/src/main/resources/catalog/components/common/map/mapService.js#L1364


      
              this.$get = function() {
                return {
                  /**
                   * Filters out background layers, preview
                   * layers, draw, measure.
                   * In other words, all layers that
                   * were actively added by the user and that
                   * appear in the layer manager
                   */
                  selected: function(layer) {
                    return layer.displayInLayerManager;
                  },
                  visible: function(layer) {
                    return layer.displayInLayerManager && layer.visible;
                  }
                };
              };
            });
          
          
          })();

So you might need to set layer.displayInLayerManager = true;
