treeview question

[kadil <ksadil bigpond com>]

I would like to use a tree-table type widget in my new application. I 
understand that a "Tree View" widget acomplishes this, however it is 
undocumented in the Tutorial and the API is quite "clinical" for a novice 
such as myself. Can someone please direct me to an example  that has more has 
a Tree View with more than one column so I can experiment with the API. 

Thanks,
Kim
