Possible to show tooltip at (point) ????

Possible to show tooltip at (point) ????

[Kevin Burton]

[-- Attachment #1: Type: text/plain, Size: 901 bytes --]

A few years ago (has it REALLY been that long?) I was playing with
x-show-tooltip so that I could display a tooltip at the given point.

I was mostly interested in this so that I could build just in time code
completion.  This way one could have a function call:

foo(

And type something like C-enter to lookup the previous symbol and show
method argument documentation in a tooltip.

..... anyway.

I needed away to have x-show-tooltip generate under (point).  Is this
possible?

If I remember I can manually position the tooltip if I know the on screen
x/y pixel cartesian position of (point) but I don't think this was possible
either.

This was with an early version Emacs 21...  Anyone know a solution to this?
 Have features been added to Emacs 22 to enable this?

There is a point-to-coord in ourcomments-util in nXhtml, but it does
not always work correctly.

I think it is possible with some hackery--you have to adjust
tooltip-frame-parameters before calling tooltip-show.  If I'm not
mistaken, doc-view mode uses a similar approach to display search
results within pdfs.

You mean by specifying top and left?  I think that is what I was going to do
to position the tooltip but first I need to find out the x/y of the current
point.

I think there is a bug with left margin. (Though I have not had time
to submit a bug report for this.)

In the predictive package?
I think one just needs to compute the left-margin width.

I wrote a tooltip-at-point package a few years ago (but never got it t work
reliably) and added this into the mix....

Here is what I have. There is indeed a problem with the left margin.
What change do you propose?

(defun point-to-coord (point)
  "Return coordinates of POINT in selected window.
The coordinates are in the form \(\(XOFFSET YOFFSET) WINDOW).
This form is suitable for `popup-menu'."
  ;; Fix-me: showtip.el adds (window-inside-pixel-edges
  ;; (selected-window)). Why?
  (let* ((pn (posn-at-point point))
         (x-y (posn-x-y pn))
         (x (car x-y))
         (y (cdr x-y))
         (pos (list (list x (+ y 20)) (selected-window))))
    pos))

Thanks..... looks like this is window relative not screen absolute.
Pretty it sure it won't work with setting the tooltip but hope to be proven
wrong :)

I'll test it later tonight.

Yes..... this DOES work but for a window that's not split.... as soon as you
split the window the coord is for the first window (not the second).
I guess I could look at the current window configuration and double the
current Y if the window is split in half....

Kind of hacky but could work for a proof of concept.

For me it works also if the window is split. The only problem I have
seen is with the margins. Maybe this is platform dependent?

I use this in nXhtml where it used for popup menus for completion in
XHTML. If you want to it is easy to test there.

What platform are you on?  What's your emacs-version?
Mine is:

GNU Emacs 22.3.2 (i386-apple-darwin9.5.0, Carbon Version 1.6.0) of
2008-09-21 on plume.sr.unh.edu - Aquamacs Distribution 1.5

Hm..... that's interesting.  So hopefully this is fixed in 23..... I can
implement a hack for 22 and then disable it under 23...

I don't see any problems with margins in current CVS or 22.3. Can you 
give a specific example?

Try this

  (point-to-coord (point))
  (posn-at-point (point))
  (set-window-margins (selected-window) 20 0)
  (point-to-coord (point))
  (posn-at-point (point))

I get the same result before and after set-window-margins.

Here's my prototype implementation of tooltip-at-point:
(defun tooltip-at-point(message)
  "This is a proof of concep for a tooltip-at-point function for
GNU Emacs.   "
  (interactive
   (list
    (read-string "Message: " )))

  (let*((mp (mouse-position))
        (x-max-tooltip-size (cons (frame-width) (frame-height)))
        (posn (posn-at-point))
        (x nil)
        (y nil))

    (setq posn-xy (posn-actual-col-row posn))
    (setq x (car posn-xy))
    (setq y (cdr posn-xy))

    (set-mouse-position (selected-frame) x y)

    ;;FIXME: see if there's a way to preserve source buffer font lock
    ;;information.  Setting a global 'face' can reset faces for EVERYTHING.
    (x-show-tip (propertize message 'face 'tooltip-at-point)
                (selected-frame)
                (list)
                tooltip-hide-delay
                tooltip-x-offset
                tooltip-y-offset)

    ;;restore the mouse position
    (set-mouse-position (nth 0 mp) (car (cdr mp)) (cdr (cdr mp)))))

... for what its worth. I also wrote a tooltip-at-point-elisp package so
that you can run C-? and lookup a symbol at point.

I can post both of these here.

It would be NICE to have an official way to do this......

I am a user of `predictive' which in my opinion has good facilities
for showing candidates. I think even that the completion stuff has
been factored out in its own package. I think it uses tooltips as one
of the options. Why don't you check it out.

Yeah...

I'm about to take the family to the beach but I will look when I get
home....

http://www.dr-qubit.org/predictive/user-guide/html/Completion-Tooltip.html#Completion-Tooltip

I *think* what they're doing is bringing up the tooltip based on a keyboard
event which *CAN* get the absolute x/y coords.

I have a different goal which is to show the tooltip during idle timeout or
when you enter an overlay.

Specifically, I'm writing a just in time compiler which compiles files right
after you save the and highlights your errors in red.

Anyway.... I'll look at the source and report back.
