Hello,
I'm trying to use the validatecommand of entry. The following code
throws an error. How do I use it correctly?
Thanks,
Frank
(defun foo ()
(with-ltk ()
(let ((e (make-instance 'entry :text "hello world!"
:validate "focusin"
:validatecommand (lambda ()
(format t
"validating...")))))
(pack e))))
(foo)
#|
invalid command name "1"
invalid command name "1"
while executing
"1"
(in -validatecommand validation command executed by .wc)
|#
