Example using x-popup-menu needed

Example using x-popup-menu needed

[Dave Neubart]

Hi All:

I need some help with  x-popup-menu.  I've searched through scores of 
.el files and the Emacs manuals looking for really simple examples --- 
but no luck.

Can someone give a very short, simple example of  using this function?

Thanks.

Dave.

How about this, which is quite hand too:

(defun my-bookmark-menu-jump ()
  (interactive)
  (bookmark-jump (x-popup-menu 
                  (list '(400 200) (selected-window)) 
                  (bookmark-menu-build-paned-menu 
                   "Select bookmark" 
                   (bookmark-all-names)))))

Unfortunately, it is not the *correct* way, which is to use keymaps.

What is delaying me from doing this the correct way, is that I haven't 
seen any simple keymaps, and I'm not sure, how to deal with commands 
such as "Goto Line" below, which is not bound to a key (but I am about 
to bind to M-g, anyway)

The example below is easy to edit, and gives Emacs a KDE/Gnome look & feel.

Really cool! But the function redo doesn't exist on my emacs
(GNU Emacs 21.3.50.1 (i386-msvc-nt5.1.2600) of 2003-09-12 on
ALABANDA).

Any idea?

If this is code for public consumption, please don't.

Try C-x b *Group* C-h k M-g

This is for public consumption. I tried C-M-g, but Emacs
seems to think that this is the same as M-g (or C-g, can't
remember which)
S-C-g nor S-M-g don't seem to distinguish, either.

I reckon that leaves "C-c g" as a global binding.

If you like that, take a look at

I defun redo in e-macs.el (maybe e-functions.el)

After the years you've spent in this newsgroup, you should know better:
it's the text terminal you're using that thinks it's a good idea to send
the same byte-sequence to Emacs in the two cases.  Emacs can't do anything
about it.  But if you use a windowing system, the problem should disappear.

> S-C-g nor S-M-g don't seem to distinguish, either.

You mean C-G and M-G ?  Same thing (except that M-G is downgraded to M-g
by Emacs if there's no binding for M-G).

As the Defining Menus section of the Emacs Lisp manual says, you should
not provide the equivalent keyboard key sequence in the menu, because
Emacs calculates them automatically.

Here's the right way to do it:

(defvar right-popup-menu
   (let ((menu (make-sparse-keymap "Commands")))
     (define-key menu [dabbrev-expand] (cons "Complete word" 'dabbrev-expand))
     (define-key menu [undo] (cons "Undo" 'undo))
     (define-key menu [grep] (cons "Search files" 'grep))
     (define-key menu [redo] (cons "Redo" 'redo))
     (define-key menu [yank] (cons "Paste" 'yank))
     (define-key menu [goto-line] (cons "Goto line" 'goto-line))
     (define-key menu [copy-region-as-kill] (cons "Copy" 'copy-region-as-kill))
     menu))

(defun right-popup-command ()		; event
   "Run the command selected from `right-popup-menu'."
   (interactive)		 
	; "e"
   (call-interactively (or (car (x-popup-menu t right-popup-menu))

(global-set-key [mouse-3] 'right-popup-command)

why do such unnecessary copying ?

You mean (x-popup-menu
          t (list menu-title
                  (cons menu-title
                        (mapcar (lambda (item)

                                item-list))))

You mean

  (call-interactively
   (choose-from-menu "Commands"
                     '(("Copy             C-insert" . copy-region-as-kill)
                       ("Goto Line"                 . goto-line)
                       ("Paste/Yank       S-insert" . yank)
                       ("Redo"                      . redo)
                       ("Search Files"              . grep)
                       ("Undo             C-_"      . undo)
                       ("Word Completion  M-/"      . dabbrev-expand))))

If you define `right-popup' as a menu keymap, you'll save yourself
the trouble of calling the commands and you'll get the hotkeys for free.

Oops, something got deleted:

Would you mind to post a complete example? I tried to insert your code
but obviously made some mistake :-(

I think C-x g is a good binding.  insert-register is also bound to C-x
r g and C-x r i, which are more logical bindings, anyway.  Thus, I
think that insert-register-compatibility-binding can be sacrificed :-)

What do people think?

Makes sense to me.  I'd also like a binding for goto-char: C-x G (C-x S-g).
