I’m very sorry, but there is no document about TkTreeCtrl.  
Please see the demo of TkTreeCtrl at “ext/tk/sample/tkextlib/treectrl/”  
on Ruby’s source tree.  
And please see the manual of TkTreeCtrl by comparison to

“tkextlib/treectrl/tktreectrl.rb”.  
`Tk::TreeCtrl::Column', `Tk::TreeCtrl::Element’,  
`Tk::TreeCtrl::Item', and `Tk::TreeCtrl::Style’ are  
classes to manipulate those component.

# a little similar to the relationship betwieen a canvas and

# canvas items.

In many cases, it may be OK to use standard style for controlling  
widget objects on Ruby/Tk.
