Best strategy to disable a touchpad on a laptop when in Emacs?

Best strategy to disable a touchpad on a laptop when in Emacs?

[Arthur Miller]

I sometimes touch the touchpad accidentally, with a palm and caouse
cursor to jump around or trigger a pop-up. How can I tell Emacs to
ignore all touchpad events? I guess they are registering as mouse
events? I don't use mouse much in Emacs, barely at all, so I oculd live
without mouse completely.

Or can I turn it off per process in the os (windows)? I can't turn the
touchpad of in the system entirely, it is my wife's and I am just
borrowing it sometimes :).

Some solutions are shown here:
https://askubuntu.com/questions/886092/how-do-i-disable-the-touchpad-while-typing

First tell what operating system do you use, and if you use X.org or
what? As solutions vary depending of the environment.

I was looking for something like how to tell emacs to ignore all mouse
events. The os is Windows, so unfortunately hacking X setup won't
help. Thanks anyway.

Forgott to say: if I got it to work via Emacs, it would be OS independent.

Find a way to disable touchpad on command line in Windows, and make
equivalent to this function below. Do you have such solution?

(defun touchpad-toggle ()
  (interactive)
  (if touchpad-toggle
      (progn
	(setq touchpad-toggle nil)
	(shell-command "xinput disable 11")
	(message "Touchpad disabled"))
    (progn
      (setq touchpad-toggle t)
      (shell-command "xinput enable 11")
      (message "Touchpad enabled"))))

Then you add some hook or process to monitor 2 seconds or more after
typing that it remains disabled.

I know how to call a shell command from Emacs Jean. I don't want to turn
off and on the touchpad every time I borrow the computer. I will sooner
or later forgett it and the best of all best ladies will be annoyed why
her computer does not work any more :). I just want it to now work in
Emacs, not in other apps. I found disable-mouse by Purcell, I'll see how
that one works.

disable-mouse works good enough seems like, at least good enough for me,
so I'll go with that. Thanks Purcell!

By the way, I just found a blog post by Malabarba (Endless Parenthesses)
about same issue:

OK you really wish to disable touchpad explicitly. I was thinking you
are finding solution to disable touchpad while typing so that palm
does not interfer with it.

Well, yes, that is what I wanted, but only in Emacs, not in other
applications. I don't wanna go click every now and then in some system
dialog or something. Disable-mouse-mode does the job.

For this function:
https://endlessparentheses.com/disable-mouse-only-inside-emacs.html

- how can we turn on that minor mode this function with the first key
  typed? That would disable the touchpad during typing.

- how can we turn off that minor mode, 2 or number seconds after
  typing?

You could put it on an idle timer, but why?

There is no reason to turn that mode on or off at all. Emacs is all
about typing keys. I don't see how I would use Emacs otherwise. I rarely
use mouse even normally on my desktop. I don't see the point of
constantly turning it on/off. It would be just unnecessary processing,
really. So I have put (global-disable-mouse-mode 1) in my init file.

By the way, to answer your previous mail too, I have seen Malabarba's
blog. Purcell's disable-mouse-mode does everything there already. You
can get it from his GH: https://github.com/purcell/disable-mouse

Proposed approach:

…and as far as I can see you got the problem solved that way.

However, have a different approach that might be applicable in some
circumstances:

Connect an external, your own keyboard when using other people’s
laptops. This way, you (1) have a comfortable and familiar keyboard,
(2) do not approach the touchpad sufficiently to accidentally touch
it.

Yes indeed, but I am away from home and don't wanna carry around a
keyboard. Disable-mouse-mode, works really fine. The touchpad still
moves pointer around; would like to turn off pointer motion too, but
presses are ignored, so it is good enough.

To disable that you could just do:

(define-minor-mode disable-mouse-mode
  "A minor-mode that disables all mouse keybinds."
  :global t
  :lighter " 🐭"
  :keymap (make-sparse-keymap))

(dolist (type '(mouse down-mouse drag-mouse
                      double-mouse triple-mouse))
  (dolist (prefix '("" C- M- S- M-S- C-M- C-S- C-M-S-))
    ;; Yes, I actually HAD to go up to 7 here.
    (dotimes (n 7)
      (let ((k (format "%s%s-%s" prefix type n)))
        (define-key disable-mouse-mode-map
          (vector (intern k)) #'ignore)))))

(disable-mouse-mode 1)
