Text widget Btn1Down is bound by default to select-start(), which you are
wiping out.
Also, this widget-callback-current-channel business has got to go. Why can't
this just be an argument to the callback? (Make it a function, not a form.)

Huh? Your suggestion as I recall!!!! I don't think it can be an argument
because of the various different types of callback that there are.

I did offer to fax you all the documentation.
Don't you have access to the sources? The Athena widgets are open source.

I seriously doubt I made this suggestion, since it's so unclean.
I don't understand when you say "the various types of callback". Are you
using
the callback for various different purposes?
Your widget callbacks should work just like any other callback: they take two
arguments, one indicating the object to which the callback was attached (an image
instance, i think), and the event that caused the callback to be invoked.

That way, the callbacks can easily figure out the dialog box and

Obviously transatlantic differences in English meaning are larger than I

No. Callbacks are allowed to be many different things - some functions,
others just forms or symbols.

No. Callbacks are allowed to be many different things - some functions,

it's very simple -- you defined the glyph widget api, including the :callback
keyword, so you can change it. none of your api is set in stone. you yourself
suggested "design should be gradual, and evolve as necessary" in response to my
suggestion to try to get things right the first time, rather than creating
hacked-up implementations; so you can hardly argue that you can't change what
you've already implemented.
the only difference is that instead of calling "Feval", call "call2".

If XEmacs was my full time job, maybe. But actually I *don't* feel like
making the effort. Supporting Athena *at all* has been a tremendous pain
for me. If you would rather I stop that suits me just fine.

This makes widget callbacks different from menubar and other callbacks. I
don't think this is user friendly and in fact breaks abstraction IMO. Feval
is not called in all cases - sometimes Fcall_interactively is used. I think
the fact that you can just drop an existing function in as a callback is a
Good Thing, so I think your latest suggestion is "unclean". Changing
widget-callback-current-channel to a function is probably an ok thing to do.

I am completely vetoing widget-callback-current-channel. How about you create
a new keyword, :new-callback, that is a function of two args, like i specified
before.
btw if you really are calling your callback using call-interactively, why don't
you declare
a function (interactive "e") and then call event-channel on the resulting
event?
that should
get you the same result as widget-callback-current-channel.
the problem with this and everything you've proposed is that there's no way, of
course,
to get at the actual widget that you were invoked from. would you propose adding
widget-callback-current-widget?

Well, you did originally....
Right now I'm not sure how important it is to get at the widget, although I
can be convinced otherwise.
