Hello,

is there any way to get a scroll mouse to be used with GNU Emacs, even if
this means recompile?

Hum, it look like mouse-wheel-mode is set to nil in your copy of
Emacs. Try put this in your .emacs:

(mouse-wheel-mode t)

In your custom.el, add the line

 '(mouse-wheel-mode t nil (mwheel))

to the custom-set-variables list.

Geez, I can't believe I made this mistake. It should read:

(setq mouse-wheel-mode t)

The former works. The latter is wrong.

According to the doc string, it should read (mouse-wheel-mode 1):

,----[ C-h f mouse-wheel-mode RET ]
| mouse-wheel-mode is an interactive compiled Lisp function in `mwheel'.
| (mouse-wheel-mode &optional ARG)
| 
| Toggle mouse wheel support.
| With prefix argument ARG, turn on if positive, otherwise off.
| Returns non-nil if the new state is enabled.
`----

But apparently the only the mode is turned off if ARG is zero or
negative:

ELISP> (cons (mouse-wheel-mode 1) mouse-wheel-mode)
(t . t)

ELISP> (cons (mouse-wheel-mode t) mouse-wheel-mode)
(t . t)

ELISP> (cons (mouse-wheel-mode 0) mouse-wheel-mode)
(nil)

ELISP> (cons (mouse-wheel-mode -1) mouse-wheel-mode)
(nil)

ELISP> (cons (mouse-wheel-mode 'foo) mouse-wheel-mode)
(t . t)

Bye, Reiner.

Yes, and that's the form I would use. (I deliberately wrote "The
former works", not "The former is correct" :).)

Seriously though, the Minor Mode Conventions say that `t' should be
OK:

    The command should accept one optional argument. If the argument
    is `nil', it should toggle the mode (turn it on if it is off, and
    off if it is on). It should turn the mode on if the argument is a
    positive integer, the symbol `t', or a list whose CAR is one of
    those. It should turn the mode off if the argument is a negative
    integer or zero, the symbol `-', or a list whose CAR is a negative
    integer or zero. The meaning of other arguments is not specified.

Thanks, you learn something new everyday. To tell you the truth, I never
had to set it up manually. It worked out of the box with CVS Emacs.

I got confused because mouse-wheel-mode is both a function and
variable. I just glanced over the variable docstring without reading it
fully. :-(

You mean the "list" that starts with a warning like:

  ;; custom-set-variables was added by Custom.
  ;; If you edit it by hand, you could mess it up, so be careful.

Please don't recommend such things to others:
Either use M-x customize-variable RET mouse-wheel-mode RET
or add (mouse-wheel-mode 1) in your .emacs.
