alternate button push?

alternate button push?

[Jack Vinson]

Is there a way to set up code for an "alternate" button press?  Normally,
I want the default button behavior in Gnus.  Sometimes, however, I want to
do something different with the thing under the button.  

For example, the code that Stefan Waldherr just sent:  Standard behavior is
to save the object.  I might want an alternate behavior that simply opens
the object for view in the article buffer (or another buffer).  With an
html link, I might want to fire up my default browser as a normal action
and fire up w3 as an alternate action.  

I was thinking that I could bind C-Return to the alternate, but it appears
there are special text properties associated with buttons and I don't know
if we can set these ourselves.

You can bind that key in the article buffer, and then the command
could just check whether it's over a button or not.

(get-text-property (point) 'gnus-data)

returns the MIME handle.

Modify `gnus-mime-button-map'.  For instance:

(define-key gnus-mime-button-map [(control return)] <your-command>)

Let me know if that doesn't work.

I had to simply define-key for [C-return] in the gnus-article-mode-map.  I
have created a function which does _something_ different with a URL, but it
isn't very elegant.  Is there a good place to look for pointers on how to
deal with the text properties that have been set for buttons?  Lars
suggested gnus-data, but I don't know what to do with it once I have it.

Try setting gnus-widget-button-keymap to something you can use.  For
instance:

(setq gnus-widget-button-keymap (make-sparse-keymap))
(define-key gnus-widget-button-keymap [mouse-2] 'your-function)
(define-key gnus-widget-button-keymap [return] 'your-function)

(defun your-function (event)
  (interactive "e")
  ...)

WIBNI if down-mouse-3 over a button would pop up a menu for doing
useful stuff with the thing represented by the button?

On a URL, this could be `View using {w3,netscape,lynx}', on a MIME
part button, this could be `Display inline', `View', `Print', `Save',
and stuff.

This doesn't do anything for me.  Gnus doesn't think [C-return] on the
gnus-widget-button-keymap is terribly interesting.  In fact 
'C-h k C-return' tells me there is nothing bound to it in the *Article*
buffer.  I set this key to gnus-article-mode-map and it works just fine.

The next question involves writing this function.  I have a rather messy
looking thing that looks at both the gnus-data text property (for MIME) and
the gnus-button-entry (for other buttons, like URL's).  Is this going to
change as Lars updates the button handling routines?

Is there an easier way to test for the kind of button that was pressed?  I
could imagine things like button-url-p, button-signature-p,
button-citation-p, button-mime-p, and so forth.

I'm not sure whether mouse-3 is the right binding, but the idea's
probably good.

 Kai> On a URL, this could be `View using {w3,netscape,lynx}', 

Do you really need something more for URLs than allowed for by
`browse-url-browser-function' (which could even pop up a menu of
choices)?  On the occasions I need to invoke a non-default browser, I
just invoke browse-url-mumble directly, but input welcome.  (I do have
it mind at some stage browse-url functions for other things such as
wgetting tarballs.)

Definitely for that one.  I might even vote for that on button-2.

[M-x customize-variable RET browse-url-browser-function RET...]
Well, there are lots of choices for browse-url-browser-function, this
is probably more than sufficient.  Only additional wish would be a way
to retrieve the data and store it on the local disk, in whatever
fashion.  (Using w3 or wget or whatever to retrieve it.)

Yes.  I want the equivalent of Netscape's "copy URL location to
clipboard".  This is especially useful when one wants to use Wget for
downloading.  I might also want to implement a "retrieve URL using
Wget" function and put it on that menu.

button3 would be a good binding for XEmacs.  I don't know about FSF
Emacs, but I think MIME buttons are on mouse-3 there, so we have a
precedent.

We already have that on button3 in XEmacs.  Doesn't it work on FSF?

That's strange.  Perhaps GNU Emacs doesn't support `:button-keymap'
for widget buttons?

Not much easier than marking the URL, is it?

That's a must. What I use at home is a function that adds the URL to a 
buffer (file). This file is later piped into wget when I'm online
again.

It is much easier, at least for me.  I am irked with having to go to
the *Article* buffer intentionally, or dragging the mouse explicitly.
