[ltk-user] new method listbox-delete

[Shawn Betts]

Hi folks,

I believe this is missing:

(defgeneric listbox-delete (l start &optional end))
(defmethod listbox-delete ((l listbox) start &optional end)
  (check-type start (integer 0 *))
  (format-wish "~a delete ~a ~a" (widget-path l) start (or end "end")))

If it isn't, what function should I be calling? :)
