Layer Groups

LayerGroup

Leaflet-Geoman can only work correct with L.FeatureGroup and L.GeoJSON (the extended versions of L.LayerGroup) we need the events layeradd and layerremove.

The following methods are available for LayerGroups on layergroup.pm:

Method	Returns	Description
enable(options)	-	Enable all layers in the LayerGroup.
disable()	-	Disable all layers in the LayerGroup.
enabled()	Boolean	Returns if minimum one layer is enabled.
toggleEdit(options)	-	Toggle enable / disable on all layers.
getLayers(deep=false,filterGeoman=true, filterGroupsOut=true)	Array	Returns the layers of the LayerGroup. deep=true return also the children of LayerGroup children. filterGeoman=true filter out layers that don't have Leaflet-Geoman or temporary stuff. filterGroupsOut=true does not return the LayerGroup layers self.
setOptions(options)	-	Apply Leaflet-Geoman options to all children.
getOptions()	Object	Returns the options of the LayerGroup.
dragging()	-	Returns if currently a layer in the LayerGroup is dragging.

Workaround to work with L.LayerGroup (Click to expand)

We are adding the same code to L.LayerGroup as in L.FeatureGroup

L.LayerGroup.prototype.addLayerOrg = L.LayerGroup.prototype.addLayer;
L.LayerGroup.prototype.addLayer = function (layer) {
  layer.addEventParent(this);
  this.addLayerOrg(layer);
  return this.fire("layeradd", { layer: layer });
};

L.LayerGroup.prototype.removeLayerOrg = L.LayerGroup.prototype.removeLayer;
L.LayerGroup.prototype.removeLayer = function (layer) {
  layer.removeEventParent(this);
  this.removeLayerOrg(layer);
  return this.fire("layerremove", { layer: layer });
};
