[Users] dynamic layer choosing

[Sarah Schuessler]

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>.
