[Users] layer tree configuration question

[Ralph Dell]

Thanks to the examples and previous forum posts I almost have my layer
tree looking exactly as I would like.

 

What I haven't been able to figure out is under  a layer check box, (in
this case Schools), I would like to display icons and text that would
correspond to  map symbology for different types of features in the
given layer.  I do not get anything displayed under the check box and
have been unsuccessful  in finding a solution.

 Any pointers or examples on how to accomplish that would be
appreciated.

 

I am pulling my layers from a group layer similar to Tasmania ( Group
Layer) in the Tree Nodes example.

 

Here is my json:

 

var treeConfig = new OpenLayers.Format.JSON().write([

  {

   nodeType: "gx_baselayercontainer",

  layer: 'Layers',

  isLeaf : false,

 loader: {

       param: "LAYERS"

  }

  },{

  text: 'School Layers',

  expanded: true,

  children: [{

   nodeType: "gx_layerparam",

   layer: 'Schools',

  param: "LAYERS",

  item: "catawba2:schools",

  text: 'Schools',

  expanded: true,

  children: [{                                                        //
under the Schools check box I want to display symbols and text that
correspond

     text: 'Elementary Schools',                     // to the symbology
that I use on the map

    IconCls: 'cc_elem'                                        // nothing
displays

    },{
// how can I add symbols and text here?

    text: 'Middle School Districts3',              // I don't even know
if using children: [{}] is the correct approach.

    iconCls: 'cc_middle'

     }]

},{

nodeType: "gx_layerparam",

layer: 'Schools',

param: "LAYERS",

item: "catawba2:elementary_school_districts",

text: 'Elementary School Districts',

iconCls: 'cc_elem_line',

}]

 }], true);
