[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 :

	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
