This works for me with Ext 3.0, 3.1 and 3.2.1.
createIconNode = function(attr) {
var layer_name = ....;
attr.icon =
'/servicesproxy/geoserver/wms?REQUEST=GetLegendGraphic&VERSION=1.0.0&FORMAT=image/png&WIDTH=20&HEIGHT=20&LAYER='
+ layer_name;
return GeoExt.tree.LayerLoader.prototype.createNode.call(this, attr);
};
And then the treepanel looks like:
{
xtype: "treepanel",
loader: new Ext.tree.TreeLoader({
applyLoader: false
}),
root: {
nodeType: "async",
children: {
nodeType: "gx_overlaylayercontainer",
text: 'Some Layers',
layerStore: myLayerStore,
leaf: false,
expanded: true,
loader: {
createNode: createIconNode
}
}
}
}
Regards,
Miles
