Here it is:

(defun tooltip-show-at-point (text)
  "Display a tooltip with TEXT near cursor."
  (let* ((oP (mouse-pixel-position))
         (tooltip-x-offset 0)
         (tooltip-y-offset (- (frame-char-height))))
    (set-mouse-at-point)
    (tooltip-show text)
    (set-mouse-pixel-position (nth 0 oP) (nth 1 oP) (nthcdr 2 oP))
    ))
