I have a TK::Tree on the left where I select an item from the tree. On the right, I have information pertaining to the selected item. I used the -browsecmd callback and this works, mostly.

The issue I have is that when no item is selected, I still display stale information for the last item selected. Is there a way to invoke the callback in theis situation with an empty string for the key?

Thanks!
