Thanks Jordah, however this is not actually a bug. It is quite deliberately
done this way. The reason is that for TreeViews, it is possible that the
item you are setting is not visible due to it being inside a collapsed
parent item. To force each item set to take focus might not be a desirable
thing. If one wants this effect though, you can do it by calling setFocus()
after you set the item.

     Example:

      setText ( {myTreeView, itema}, "New Text for A")
      setText ( {myTreeView, itemb}, "New Text for B")
      setFocus( {myTreeView, itema})

-----------
Derek.
