[mapguide-users] Fusion and Viewer API Reference

[Paul Spencer]

Jim,

unfortunately we have not developed a compatibility API for the  
existing Viewer yet.  There will be one that supports a limited set of  
Viewer API functions shortly, but it won't include GetLayers.

The code to do this now will be a bit ugly, but it would look  
something like this:

function GetLayers() {
     var mapWidget = Fusion.getMapById('Map'); //the id of the div  
that the map is in
     var mapguideMap = mapWidget.aMaps[0]; //
     var layers = mapguideMap.aLayers;
     for (var i=0; i<layers.length; i++) {
         //now you can do something with layers.
         var layer = layers[i];
     }
}

Each 'layer' object has the following properties:

layer.layerName
layer.uniqueId
layer.resourceId
layer.legendLabel
layer.selectable
layer.selectedFeatureCount
layer.layerTypes
layer.displayInLegend
layer.expandInLegend
layer.visible
layer.actuallyVisible
layer.editable

You can also access the logical structure of groups and layers through  
mapguideMap.layerRoot.

Cheers

Paul
