I will do.

Ok, I think I now fully understand your recipe. My own recipe was in
fact over-simplified for what I wanted to show.
So I now change '-1' to '-3' in it, i.e. :
(let (oposn opoint)
(widget-create 'checkbox) ; point is left after the widget
(setq oposn (posn-at-point)
opoint (point))
(forward-char -3) ; cursor now on the widget.
(message "Old: %s (Point at %d)\nNew: %s (Point at %d)"
oposn opoint
(posn-at-point) (point)))
and that still shows the surprising result. In other words, if in a
blank buffer I do
M-: (progn
(widget-create 'checkbox)
(goto-char (point-min))
(posn-x-y (posn-at-point))) ;; or (pos-visible-in-window-p nil nil t)
then I do not get (0 0) -- that is is unexpected to me.
