Have you tried extending the LayerLoader'?
extend: 'GeoExt.tree.LayerLoader',
createNode: function(attr) {
I had to extend the layer container and use a custom loader. This allowed me to
add text and an icon to the node.

Subject: [Users] How to add multiple components to a tree store node
Hello,
I'm trying to add a WMS legend AND an opacity slider to each node of a tree
store.
I can add each component separately, but not together ...
It could be something like this, but attr.component = [{...}, {}] raises errors
.. :
var tree_store = Ext.create('Ext.data.TreeStore', {
model: 'GeoExt.data.LayerTreeModel',
root: {
expanded: true,
children: [
{
// Base layers
plugins: ['gx_baselayercontainer'],
expanded: true,
text: "Base maps"
},
{
// Overlays
plugins: [{
ptype: "gx_overlaylayercontainer",
loader: {
createNode: function(attr) {
attr.component =
[
// Add a WMS legend to each node created
{
xtype: "gx_wmslegend",
layerRecord:
mapPanel.layers.getByLayer(attr.layer),
showTitle: false,
baseParams: {
// Overrides gif format that is ugly in this
case
FORMAT: 'image/png',
LEGEND_OPTIONS: 'forceLabels:off'
},
},
// Add an opacity slider
{
xtype: "gx_opacityslider",
layer: attr.layer,
vertical: false,
value: 100,
//x: 100,
//y: 100,
width: 200,
aggressive: true,
listeners: {
change: function(slider, val) {
attr.layer.setOpacity(val/100);
}
}
}];
return
GeoExt.tree.LayerLoader.prototype.createNode.call(this, attr);
}
}
}],
expanded: true,
text: "Layers",
}]
}
});
Any idea?
Thanks,
Juliette
