How to display the path of selected node of a tree table.

Question

Hi,
I have one use case where I have to display the path of node of tree table which is selected one.
e.g.
Suppose the tree table is like this.
Folder1(root)
          ->folder2
          ->folder3
                    ->folder4
Now when I select this folder1 then path display should be "/folder1(root)"
when i select the folder4 then path should be "/folder1(root)/folder3/folder4"
Hope this one will help to understand my use case..
Thanks
