[Users] How to expand node of TreePanel using a button

[Vidal, Antoni]

Hello list,

 

I would like to expand a node of a TreePanel when user click on a button in 
toolbar.

 

Code of button:

 

dowldctrl = new OpenLayers.Control();

        action = new GeoExt.Action({

            control: dowldctrl,

            tooltip: "Download",

                                               id: 'infobtn',

            map: map,

            iconCls: 'dowldbutton',

            toggleGroup: "tools",

                                               toggleHandler : 
function(actionObj, checked) {

                                                               if(checked){

                                                                              
map.getControlsByClass("Click")[0].activate();

                                                               }else{

                                                                              
map.getControlsByClass("Click")[0].deactivate();

                                                               }

                                                               

                                               }

        });

                               actions.push(action);

 

Any idea?

 

Thank's in advance.
