[Users] Question about turning on entire group of layers in layercontainer/treenode

[Andrew Stewart]

Sorry didn't realize it was pasted all messed up, here is the code a little more readable thanks



        //Labels LayerList
        var layerList_Labels = new GeoExt.tree.LayerContainer({
        text: 'Labels',
        layerStore: mapPanel.layers,
        leaf: false,
        cls: 'rootnode',
        enableDD: true,
        expanded: false,
        loader:
        {
            filter: function(record)
            {
                var myarr = new Array();
                myarr[0] = record.get("layer").name.indexOf("Overview Streets");
                myarr[1] = record.get("layer").name.indexOf("Quadrant Streets");
                myarr[2] = record.get("layer").name.indexOf("Neighbourhood Streets");
                myarr[3] = record.get("layer").name.indexOf("Block Streets");
                myarr[4] = record.get("layer").name.indexOf("Proposed Streets");
                myarr[5] = record.get("layer").name.indexOf("Address Label (Overview)");
                myarr[6] = record.get("layer").name.indexOf("Address Label (Detail)");
                if(myarr[0]==-1 && myarr[1]==-1 && myarr[2]==-1 && myarr[3]==-1 && myarr[4]==-1 && myarr[5]==-1 && myarr[6]==-1)
                {
                return false;
                }
                else
                {
                return true;
                }
            }
            }
        });


        //declare root tree node
        var layerRoot = new Ext.tree.TreeNode({
            enableDD: true,
            text: "All Legend Items",
            expanded: true
            });

       //add children to root node
       layerRoot.appendChild(layerList_Labels)
       layerRoot.appendChild(layerlist_AOI)
       layerRoot.appendChild(layerlist_Trails)
       layerRoot.appendChild(layerlist_Footprints)
       layerRoot.appendChild(layerlist_LegalFabric)
       layerRoot.appendChild(layerlist_ParcelFabric)
       layerRoot.appendChild(layerlist_Base)
       layerRoot.appendChild(layerlist_Orthos)


        var layerTree = new Ext.tree.TreePanel({
        title: '',
        renderTo: 'legend',
        root: layerRoot,
        enableDD: true,
        applyLoader: true,
        rootVisible: false

Dude,

Is it possible for you to indent your code ? It's really easier to read and to understand it...

Thanks !

 I have a layerlist that is working fine and being entered into a layercontainer/treepanel to show all my layers. Everything works fine but I am wondering if there is a way to turn on all layers by adding a checkbox to the group much like checkboxes are next to all individual layers I have. Appreciate any advice on how to modify my existing code to accomplish this so I can turn all my layers on by clicking the group (root layer) or if there is another way to do this, thanks.
