[ka-Map-users] keeping only one layers on

[Paul Spencer]

You would need to do this programmatically in javascript and provide  
your own user-interface for doing this.

The critical part of the code would look something like:

function turnLayerOn(name) {
     var map = myKaMap.getCurrentMap();
     var layers = map.getAllLayers();
     for (var i=0; i<layers.length; i++) {
         layers[i].setVisibility(layers[i].name == name);
     }
}

and in your HTML, you would have controls (buttons, select etc) that  
would call turnLayerOn with the name of the layer to turn on.

Cheers

Paul
