[ltk-user] wrong # args when trying to setup a command for the scale widget
by Russell Kliese 16 Nov '09

Hi, I'm getting the following error reported when trying to setup a command to be executed when a scale widget is changed: wrong # args: should be "callback s" wrong # args: should be "callback s" while executing "callback w4 0" (command executed by scale) The following code reproduces this error. (defun command-test() (ltk:with-ltk () (let* ((f (make-instance 'ltk:frame)) (b1 (make-instance 'ltk:button :master f :text "Button 1" :command (lambda () (format t "Button~&")))) (scale (make-instance 'ltk:scale :master f :command (lambda (val) (format t "Scale val:~D~&" val))))) (ltk:pack f) (ltk:pack b1 :side :left) (ltk:pack scale :side :left) ))) I'm using LTK 0.91. Perhaps this is caused by a bug in the command sent to tk to set up a callback. Any pointers to the part of the code I should look at to fix this problem would be appreciated. Cheers, Russell

I just saw these posted on usenet. They appear to be another set of "megawidgets", now with LTK bindings. http://coding.derkeiler.com/Archive/Lisp/comp.lang.lisp/2009-11/msg00208.ht… Or go directly to the project and lisp docs at http://gestaltitems.sourceforge.net/ http://gestaltitems.sourceforge.net/lisp/index.html Later, Daniel

[ltk-user] :textvariable

Hi, I get an error if I try to use a :textvariable in a label: (with-ltk () (let ((foo "")) (make-instance 'label :textvariable foo))) Invalid initialization argument: :TEXTVARIABLE In fact, when I expand the code to create a label class in ltk.lisp I see that there's no :textvariable key: (defwidget label (tktextvariable widget) () "label") And the textvariable that is being generated is text_<value of :text>. Any chance this can be fixed in the next release? Cheers, Pedro
