[Users] dynamic layer choosing

[Dan Ramage]

Don’t know if this helps, but here:
http://carolinasrcoos.org/carolinasrcoos.html is how I handled I think what
you are asking about.

The check box turns on the layer, clicking the radio button will enable
GetFeatureInfo requests for that layer when you click on an item in that
layer.

Hi Eric,

I have add radio buttons.
So I think that I need to register a listener if I check one of my radio
button like this one:

listeners: {


            "radiochange": function(node){


               // alert(node.layer.name + " is now the the active layer.");


                node.getattributes();


            }

I will take a deeper look at the api. Or do you perhaps have a little
example?

Thanks a lot.
best regards
Sarah

Hi

One option would be to add radio buttons to layer nodes in the layer
tree. See <http://dev.geoext.org/trunk/geoext/examples/tree.html>.
