[Gambas-user] How to search for an item in a treeview

[Stephen Bungay]

   Yes, your original post did not ask for anything to be repopulated.. 
indeed, nothing has been removed from the treeview so you don;t have to 
repopulate it using this method.
   Could you be a little more clear on what it is you are trying to 
accomplish? We have the find done.. whats with the repopulate?
