Thanks Terry, sorry I missed your previous mention of this. From what I recall 
the treeview doesn't allow editable items, but what I've done in similar 
circumstances before (editing text items on a canvas in drawing type programs) 
was 'place' an entry widget on top of it at the right location as needed and 
then get rid of the entry when done, which provides the correct effect.

You know what, I think I know why they might have used an Entry widget... for 
really long values of variables the entry can stay a fixed width and will 
horizontal scroll, but a label will expand to the size of the content
