[Users] Additional checkboxes

[Mehmet Sirin]

Okay, got one solution. Now I'm able to chose several radiobuttons at
once. Also a radiobutton is unchecked if you click it again. If
someone aims the same: You have to remove name="', a.radioGroup,
'_radio"  in RadioButtonMixin.js. Then play with onClick method:
if(el) {
       if(!this.node.layer.myChecker){
            el.checked=true;
            this.node.layer.myChecker=true;
        }
    ...
with el.checked=true/false you can select/unselect the radiobutton.

I had forgotten some basic things (because it is not in the LayerTree
tutorial on the Geoext homepage):

1. var LayerNodeUI = Ext.extend( GeoExt.tree.LayerNodeUI, new
GeoExt.tree.RadioButtonMixin() );
2. adding              baseAttrs: {radioGroup: "root",uiProvider:
"use_radio"} to loader of a LayerContainer

3. adding              applyLoader: false,
                           uiProviders: {
                                      "use_radio": LayerNodeUI
                           }   to loader of TreePanel.


Maybe a beginner need this..
