Tree`s node editor

I want to create tree editor. But i don,t know how to make renaming of nodes. I want to make it like Windows renaming, i.e. current name become editable and copyable, when i press menu button 'edit'.
How i can do that?

Have you tried the cell editing plugin from the grid to see how far that gets you?

No, because I don,t understand how to use it.
If I do that:

Code:

---

var cellEditing= Ext.create('Ext.grid.plugin.CellEditing', {
        clicksToEdit: 1
        });
 var tree = Ext.create('Ext.tree.Panel', {
            id: 'tree',
            store: store,
            width: 250,
            height: 300,           
            rootVisible: false,
            border:0,
            viewConfig: {
                plugins: {
                    ptype: 'treeviewdragdrop',
                    appendOnly: true,
                    [cellEditing]
                }           
            }
        });

---

I get error "SyntaxError: invalid property id" on string "[cellEditing]". Where is the problem?

As I understand, for using cellEditing, I should use property "columns".
But I don`t need menu,which is created for columns.
I just need possibility to edit name only for folders by doubleclicking and from menu. How I can make this?
