Question

I have the following elisp:

(require 'widget)

(eval-when-compile
  (require 'wid-edit))

(defun testit ()
  (interactive)

  (switch-to-buffer "*Widget Test*")

  (widget-insert "Test field: ")
  (widget-create 'editable-field
         :size 25
         :notify (lambda (widget &rest ignore)
               (message (widget-value widget))))

  (use-local-map widget-keymap)
  (widget-setup))

It creates a text widget in a new Emacs buffer. I intend it to show the value of the widget in the minibuffer on each change, but it doesn’t seem ever to call the :notify function. Why not?

Answer 1

It appears that it didn’t work because I had unknowingly messed up widget.el and needed to reload the package. Restarting Emacs did the trick.
