Re: [Users] Add all geoserver layers automatically

[Valiquette,Francois [Montreal]]

Hello,

 

I tried your code with my WMS server and it does not work. The tree is empty.

Hi François,

I just tried it with the following code, but there are no nodes listed in the 
tree.
Could the url parameter be the problem?: http://localhost:8080/geoserver/wms

var root = new Ext.tree.AsyncTreeNode({
   text: 'All Layers', 
   loader: new GeoExt.tree.WMSCapabilitiesLoader({
      url: 'http://localhost:8080/geoserver/wms', 
      layerOptions: {buffer: 0, singleTile: true, ratio: 1},
      layerParams: {'TRANSPARENT': 'TRUE'}, 
      // customize the createNode method to add a checkbox to nodes 
      createNode: function(attr) {
         attr.checked = attr.leaf ? false : undefined; 
         return 
GeoExt.tree.WMSCapabilitiesLoader.prototype.createNode.apply(this, [attr]); 
     } 
   }) 
});

tree = new Ext.tree.TreePanel({ 
   root: root,
   region: 'west',
   width: 250,
   listeners: { 
      // Add layers to the map when ckecked, remove when unchecked.
      // Note that this does not take care of maintaining the layer order on 
the map.
     'checkchange': function(node, checked) {
         if (checked === true) {
             mapPanel.map.addLayer(node.attributes.layer);
         } else {
             mapPanel.map.removeLayer(node.attributes.layer);
         }
      } 
   }
});

regards, Chris

        Hello Chris,

         

        Yes you can, you need to make a query on your server to get the 
GetCapabilities XML (a list of all the available layers and options).

        The GeoExt.data.WMSCapabilitiesStore can make the query for you by 
giving it an URL. Then, it will return you a set of records. Afterward with the 
records, you can generate manually a Tree for a greater flexibility.

        Otherwise, I think you can use GeoExt.tree.WMSCapabilitiesLoader to 
generate the Tree automatically for you. 

         

        Here is an exemple of a valid XML file :

        http://api.geoext.org/1.1/examples/data/wmscap.xml

        Hi,

        I saw some examples that had a List of available layers and a button 
that you could click to add a selected layers to the map.
        Is it possible to have all layers on a Geoserver instance automatically 
added to the map.
        This would eliminate the need to change the JS code when a new layer is 
added to Geoserver.

        regards, Chris
