[Users] How to add array of layers / LayerStore to map

[Matt Priour]

Your map panel config should be:

                xtype:    'gx_mappanel',
                title:    'Maps',
                split:     true,
                map:    mainMap,                
                layers: [layerList]}

it is layers not layer and zoomTo is not a valid config option. You can use zoom, center or nothing and the map will start at maxExtent

Subject: [Users] How to add array of layers / LayerStore to map


 Hello all,

I tried to add an array of layers to my map object but it fails. First I have created some layers and added these to a layerlist (=array) which is also used for a layer tree. How can I add this array to the map? Do I have to create a GeoExt.data.layerStore?
Thank you for some sugestions...

Here the relevant code:

/*
*    Layer
*/
var OLwms = new OpenLayers.Layer.WMS(
            "Topographic map",
            "http://labs.metacarta.com/wms/vmap0", 
            {layers: 'basic'},
            {isBaseLayer: true}
              );
            
var BMwms = new OpenLayers.Layer.WMS(
             "Blue Marble Global Imagery",
              "http://sigma.openplans.org/geoserver/wms?",
              {layers: 'bluemarble'},
            {isBaseLayer: true }
            );
        
var NASAwms = new OpenLayers.Layer.WMS( 
            "NASA WMS",
            "http://wms.jpl.nasa.gov/wms.cgi?", 
            {layers: 'BMNG', format: 'image/png'},
            {isBaseLayer: true}
            );
...

/*
*    Array with layers
*/

var layerList =[{    
                text: 'Background Layers',
                leaf: false,                    
                expanded: true,
                children: [{
                    nodeType: 'gx_layer',
                    layer: OLwms,
                    checked: false
                    }, {
                    nodeType: 'gx_layer',
                    layer: BMwms,
                    checked: false
                    }, {
                    nodeType: 'gx_layer',
                    layer: NASAwms,
                    checked: false
                    },
                    ...
                ]
}];
...

/*
*    the map panel
*/

var mainPanel = new Ext.Panel({
            region:    'center',
            deferredRender: false,
            margins:        '5 5 5 5',            
            activeTab: 2, 
            items:[
            {
                xtype:    'gx_mappanel',
                title:    'Maps',
                split:     true,
                map:    mainMap,                
                layer: ([layerList]),
                zoomTo:    'maxExtent',
            }]
 });    



Best regards,
Christian
