Hi all,
The following snippet inserts a button with a long label and a wrap-prefix.
Clicking the prefix causes an error, whose backtrace is shown below.
(with-current-buffer (get-buffer-create "*button*")
(erase-buffer)
(insert-text-button
(let ((str "long long long long text "))
(concat str str str str str))
'follow-link t
'action (lambda (&rest args) (print args))
'wrap-prefix "this is the wrap prefix")
(pop-to-buffer (current-buffer)))
Debugger entered--Lisp error: (void-function nil)
nil(("this is the wrap prefix" . 9))
button-activate(("this is the wrap prefix" . 9) t)
push-button((mouse-2 (#<window 13 on *button*> 81 (76 . 29) 379842354 ("this
is the wrap prefix" . 9) 81 (9 . 1) nil (4 . 12) (8 . 17))))
funcall-interactively(push-button (mouse-2 (#<window 13 on *button*> 81 (76 .
29) 379842354 ("this is the wrap prefix" . 9) 81 (9 . 1) nil (4 . 12) (8 .
17))))
call-interactively(push-button nil nil)
command-execute(push-button)
Cheers,
Clément.
