Coming back ... - the code below seems to do what I want. Comments,
suggestions? Can someone please test on X? Mac?
Changes to tooltip.el:
(defvar tooltip-mouse-pixel-position nil)
(defun tooltip-timeout (object)
"Function called when timer with id tooltip-timeout-id fires."
(if (and
(equal (nth 0 tooltip-mouse-pixel-position) (nth 0
(mouse-pixel-position)))
(> 10 (abs (- (nth 1 tooltip-mouse-pixel-position) (nth 1
(mouse-pixel-position)))))
(> 10 (abs (- (nthcdr 2 tooltip-mouse-pixel-position)
(nthcdr 2 (mouse-pixel-position))))))
(progn
(run-hook-with-args-until-success 'tooltip-hook
tooltip-last-mouse-motion-event))
;;(message "%s ### %s" tooltip-mouse-pixel-position
(mouse-pixel-position))
))
(defun tooltip-start-delayed-tip ()
"Add a one-shot timeout to call function tooltip-timeout."
(setq tooltip-mouse-pixel-position (mouse-pixel-position))
(setq tooltip-timeout-id
(add-timeout (tooltip-delay) 'tooltip-timeout nil)))
