tooltip-show with a timer

tooltip-show with a timer

[Erik Iverson]

Hello all,

Could someone help me understand what is going on here?

Define a function called moving-tooltip, which simply shows a tooltip that says 
"hi".


(defun moving-tooltip ()
  (tooltip-show "hi"))

Then, hook the new function up to a timer that runs every two seconds.

(run-with-timer 1 2 'moving-tooltip)

Let the mouse come to rest, and you'll see the tooltip.  Don't move the mouse, 
and the next time the tooltip timer is called, the tooltip gets moved 
(specifically, to the upper-left corner of my screen).

Any ideas as to what is happening here?

I'd love it if the tooltip just stayed where it was if the mouse didn't move.

Thanks,
Erik

If you don't know, you can then cancel the timer with

M-x cancel-function-timers <RET> moving-tooltip <RET>

If you want to cancel timer you have to set it explicitely:

,----
| (setq my-timer (run-with-timer ....))
| (cancel-timer my-timer)
`----

,----[ C-h f tooltip-show RET ]
| tooltip-show is a compiled Lisp function in `tooltip.el'.
| 
| (tooltip-show text &optional use-echo-area)
| 
| Show a tooltip window displaying text.
| 
| Text larger than `x-max-tooltip-size' is clipped.
| 
| If the alist in `tooltip-frame-parameters' includes `left' and `top'
| parameters, they determine the x and y position where the tooltip
| is displayed.  Otherwise, the tooltip pops at offsets specified by
| `tooltip-x-offset' and `tooltip-y-offset' from the current mouse
| position.
| 
| Optional second arg use-echo-area non-nil means to show tooltip
| in echo area.
