Thanks for the hint, Jason! But I am still struggling. Your example works fine. But it covers only a single text widget. I am trying to scroll a collection of widgets, like this: (defun scrolltest () (with-ltk () (let* ((root (make-instance 'frame)) (button-list (make-instance 'listbox :master root)) (scrollbar (make-instance 'scrollbar :master root :orientation :vertical)) (quit-button (make-instance 'button :master root :text "Quit" :command (lambda () (setf *exit-mainloop* t))))) (pack root :side :top) (pack quit-button :side :bottom :pady 10) (pack button-list :side :left) (pack scrollbar :side :left :expand t :fill :y) (configure scrollbar "command" (format nil "~a yview" (widget-path button-list))) (configure button-list :yscrollcommand (format nil "~a set" (widget-path scrollbar))) (dolist (button-number '(1 2 3 4 5 6 7 8 9 0)) (let ((b (make-instance 'button :master button-list :text button-number :command (lambda () (format t "~a~%" button-number))))) (pack b :side :top :anchor :w)))))) The widgets simply don't seem to be connected :-( I have also tried with a frame instead of a listbox, but frames don't seem to support the yscrollcommand. -- Josef Wolf jw@raven.inka.de
