[OpenLayers-Users] Change default image in tree node with GeoExt/Extjs

[Cristhian Boujon]

Hello all,

I'm using GeoExt (based on ExtJs) to create a tree. In each node I want the
corresponding image at left instead of the default image [image: default
image] like this site <http://todosmiscomercios.com.ar/>. How can I do it?
Here is part of my code:

var bpn = new OpenLayers.Layer.WMS("bpn",
    url,
    {
        LAYERS: [ 'Año 2004', 'Año 2005', 'Año 2006', 'Año 2007', 'Año 2009'],
        format: "image/png",
        transparent: "true",
        projection: 'EPSG:4326'
     },
     {
         buffer: 0,
         displayOutsideMaxExtent: true,
         isBaseLayer: false,
         displayInLayerSwitcher: false,
         yx: {'EPSG:4326' : true}
      });
var treeConfig = [
    {
        nodeType: "gx_layer",
        layer: bpn,
        isLeaf: false,

        loader: {
            param: "LAYERS",

        },
        expanded: false
    }];

tree = new Ext.tree.TreePanel({
    border: true,
    region: "west",
    title: "Entre Ríos",
    width: 250,
    split: true,
    collapsible: true,
    collapseMode: "mini",
    autoScroll: true,

    loader: new Ext.tree.TreeLoader({
        applyLoader: true,
        uiProviders: {
            "layernodeui": LayerNodeUI
        }
    }),
    root: {
        nodeType: "async",
        children: treeConfig
    },
    rootVisible: false,
    lines: false,});


Each layer (node) 'Año 2004', 'Año 2005', 'Año 2006', 'Año 2007', 'Año
2009' has a different image. What should I change in treeConfig?

Regards,
