Remove Org and Tbl from menubar for derived mode

Remove Org and Tbl from menubar for derived mode

[Christian Wittern]

Hi there,

I am developing a mode derived from org for special editing and browsing 
purposes.  I will add my own menu to the menubar and would like to remove 
the menus added by org, "Org" and "Tbl", in order not to confuse my users, 
who will be Emacs newbies in most cases.
I tried several things like

(define-key org-mode-map [menu-bar Org] nil)
or
(define-key global-map [menu-bar Org] nil)
and some other combinations of this line of thought, but nothing succeeded 
in removing the stuff.

I wonder if anybody here has any advice?

All the best and thanks in advance,

Christian

Interesting question, and I do not know the answer.  Only that you certainly should not change the org-mode-map, because such changes would have effects in all Org mode buffers.

I have never defined menus, but a quick look tells me you use
define-key.  If that is correct, then can't you just redefine the Org
and Tbl menu to nil?  I believe if you do that with regular key
sequences, any existing bindings get removed.

Just a thought.

Oops, Christian already tried that!  I guess it's time for me to go to
bed :-p.

Not really an advice, just a hint: doesn't org-mode itself use easy-menu
to remove outline from the menu bar?

Yeah, I have seen that.  The problem is the way easy-menu-remove is defined:

easy-menu-remove is an alias for `ignore' in `easymenu.el'.

And the docstring explains:
<quote>
Remove MENU from the current menu bar.
Contrary to XEmacs, this is a nop on Emacs since menus are automatically
(de)activated when the corresponding keymap is (de)activated.
</quote>

In addition to that, it seems that this is not removing the top-level menu, 
but some of the sub-menu entries (... if I understand this correctly...).

And, as Carsten reminded me, what I do *not* want to do is de-activate 
org-mode's keymap:-)

So still wondering...

The elisp manual says (sec. 22.17.5, "The Menu Bar"):

,----

Try this

    (add-hook 'org-mode-hook
              (lambda nil
                (local-unset-key [menu-bar Org])))

Thanks, if I do this for my derived mode, it does exactly what I need!
