[OpenLayers-Users] como mostrar capas no base como radio button?

[Jorge Gustavo Rocha]

Hi Salo,

0) Do you want all layers (base+overlays) in a single radio group, or 
only the overlays in a separated radio group?

The fastest way to have two radio groups is to change 2 lines of code in 
OpenLayers-2.11/lib/OpenLayers/Control/LayerSwitcher.js

i) Look for the 'redraw' method.
First ensure that <input> tags from base layers and from overlay layers 
get different group names. Change this:
// inputElem.name = (baseLayer) ? this.id + "_baseLayers" : layer.name;
inputElem.name = (baseLayer) ? "baseLayers" : "overlays";

ii) Look for the 'onInputClick' method.
You must improve the onInputClick method, on the same file, since the 
test is poorly written.
Change this:
// if (this.inputElem.type == "radio") {
if (this.layer.isBaseLayer) {

I think these two lines are the necessary changes. Please test it properly.

Regards,

Jorge
