Hi
I want to get a tip's information created by x-show-tip, for example: width, height, x and y
but I fail to find the way, anyone can help me?
by the way, is a tip a window or a frame?
thanks very much :-)

A tooltip is a frame, when Emacs creates it itself; in that case, you
should be able to find the values in tooltip-frame-parameters. But
with some toolkits, notably with GTK, the tooltip is by default
produced by the toolkit, and in that case I think the settings are in
the toolkit configuration files, out of Emacs control.

We have invested some efforts to hide information about the tooltip
implementation. The major reason was to protect our own routines from
operating on tooltip frames and windows. Compare, for example,
http://lists.gnu.org/archive/html/emacs-devel/2018-02/msg00694.html
From there you can see that the return value of 'visible-frame-list'
and the 'tooltip' frame paramter can give you the current tooltip
frame if it is visible and native (that is created by Emacs itself).
The size and position paramters of that frame should give you the
values you cited above.

'tooltip' (or 'tip') usually refer to the text only. Emacs can put
that text into a window, that window into a frame and ask the window
system to display that frame in a window-system window. But Emacs can
drop that text directly to GTK in which case no frame will be made.
For GTK tooltips no information can be retrieved.

I use the following code to test, but failure
1. width and height parameter do not work
2. I can find any frame with 'tooltip parameter
```
(setq tooltip-reuse-hidden-frame t)
(setq x-gtk-use-system-tooltips nil)
(progn
(x-show-tip "this is a test"
(selected-frame)
'((name . "tooltip1")
(internal-border-width . 2)
(left . 200)
(top . 300)
(width . 200)
(height . 600)
(border-width . 1)
(no-special-glyphs . t))
100 0 0)
(dolist (frame (visible-frame-list))
(princ (frame-parameter frame 'tooltip))))
```

This may hide the frame from 'visible-frame-list'.

On linux (guixsd), emacs master, I can see the tooltip but print nil
(setq tooltip-reuse-hidden-frame nil)
(progn
(x-show-tip "this is a test"
(selected-frame)
'((name . "tooltip1")
(internal-border-width . 2)
(left . 200)
(top . 300)
(width . 200)
(height . 600)
(border-width . 1)
(no-special-glyphs . t))
100 0 0)
(dolist (frame (visible-frame-list))
(when (frame-parameter frame 'tooltip)
(princ (frame-parameters frame)))))

What happens if you set x-gtk-use-system-tooltips to nil?

Does this mean: when tooltip-reuse-hiden-frame is t, the return of visible-frame-list
will always do not show tooltip frame, no matter tooltip actuly show or
hide?

No. While the tooltip is shown the tooltip frame is on
‘visible-frame-list’.

Thanks for the information :-)
x-show-tip's background-color works well, but
can not change foreground-color, does it do not support foreground-color?
```
(progn
(x-show-tip
(substring-no-properties
"
this is a test
this is a test
this is a test
this is a test")
(selected-frame)
'((name . "tooltip")
(internal-border-width . 2)
(background-color . "white")
(foreground-color . "red")
(left . 200)
(top . 300)
(border-width . 1)
(no-special-glyphs . t))
10 0 0)
(dolist (frame (visible-frame-list))
(when (frame-parameter frame 'tooltip)
(princ (frame-parameters frame)))))
```

Haven't been following this thread. But yes,
you can change the foreground color. E.g.:
(x-show-tip
(propertize "cuckoo" 'face `(:foreground "red"))
(selected-frame)
nil
5)
Perhaps you can't do it using an alist, though.
I don't recall - but that's probably why I do
it as shown above.

I forgot to answer that: Emacs adjusts the tooltip window size
according to the contents of the tooltip. So width and height are
calculated internally and your parameters are not respected.
