[Users] How do I create a WMS Capabilities Tree in GeoExt 2?

[Christian Mayer]

Hi Andrew,

you are right the WMSCapabilitiesLoader has gone in GeoExt 2. To get a "WMS Caps Tree" you have to put some things together on your own. I can give you some hints, which can be a starting point:
  - Parse the WMS Caps with the GeoExt.data.WmsCapabilitiesLayerStore [1] to have records holding layer objects representing the WMS layers [2]
  - Transform the layers to a LayerStore [3]
  - Implement a custom LayerLoader [4] and add it to a LayerContainer [5]
  - Finally the LayerContainer can be used as a plugin in a TreeStore like its done in this example [6]

As I said, these are just some hints how this could be achievable. If you are successful it would be nice if you could share the code, maybe we can create an official example showing this.

Cheers,
Chris

Betreff: [Users] How do I create a WMS Capabilities Tree in GeoExt 2?

I am trying to create a WMS Capabilities Tree in GeoExt 2, similar to this example:

http://api.geoext.org/1.1/examples/wms-tree.html

However that example uses WMSCapabilitiesLoader which has been removed from GeoExt 2.  How do I achieve the same thing?

Thanks,

Andrew
