You need to study the docs for the Tree widget in the BWidget package,
e.g. via http://tcllib.sourceforge.net/BWman/Tree.html. 

I think that you can do something like

tcl(mytree, "bindText", "<Button-1>",
                         function(node)print(node)) 

(As multiple hints in the wording should tell you, this is completely
untested)
