Hi Peter,
Please consider the attached patch against http://ltk.rplay.net/svn/branches/ltk/repl@215
It implements several essential treeview commands; they are being used to implement a symbol/package browser for ABLE. http://common-lisp.net/project/able/
The attached treeview-example.lisp demonstrates their usage. * (load "treeview-example.lisp") * (ltk-user::show-symbols :ltk-user)
Thanks, Daniel
