                                        }
                                    ]
                                },

You should put the itemclick listener on the tree panel itself.

Also, please post threads in the appropriate forum. I have moved this one.

Ok Thanks but, in what part of my code? in ExtJs 3.3.x i've put my Listener event in the same place of my piece of code and works perfect, but in my ExtJs 4.0 example code where?

[mitchellsimoens]

I said on the tree panel itself. So in the same level as the xtype : 'treepanel'

Ok Thanks, I saw much change, ExtJs ExtJS 3.x and 4.x, here is my code and resolved: items: [ { xtype: 'treepanel', title: 'Catalogos', height: 212, iconCls:'catalogos', forceLayout: true, collapsed: true, collapsible: true, rootVisible: false, border: false, autoWidth: true, listeners:{//Listeners apuntando a cada node itemclick:function(view, record, item, index, e) { if (index==1) { addTab(); } if (index==2) { Ext.Msg.alert('Title','Indice 2'); } } }, bla. bla. bla
