Thanks for the link, but it's no help to me.
Well it would have been if you'd taken it as a starting point in
looking for what you were after... if you look on the Introduction
page for the document mmalc pointed you at, you'll find a link to this:
http://developer.apple.com/documentation/Cocoa/Conceptual/
CurrencyConverterBindings/
which should make the answer to your original question fairly
obvious. If you work through that example, and (maybe) compare it
with the original currency converter sample (which doesn't use
bindings), I think you'll find it easier to understand.
Apple's reference docs have Cocoa-savvy people as their target
audience,
not newbies like me. I've tried to read the one you pointed at, but
it was
the same frustration as with some other refdocs I tried before.
Apple's Guide documentation (which is what you were pointed at) is
actually quite good, but it does have to assume some prerequisites
otherwise it'll be restating the basics all the time, which will get
in the way of what it's trying to explain. The Introduction pages
usually state what the author of the document expects you to have
read (and understood), so you can tell when you're getting in over
your head, and also where you need to look to avoid that problem.
(Perhaps someone should draw a chart of all of the documents and
their pre-requisites so that people who want to study a particular
topic can see what they need to learn first...)
They are simply not aimed at newbies like me.
Some of them are, some of them aren't, and there are different types
and levels of newbie. It's possible (for instance) to be an expert
on vanilla Cocoa, but to be a newbie at bindings or Core Data. I'm
in the latter camp myself... I haven't really used Core Data at all
to date, because of the kinds of apps I work on. So there, I'm a
newbie (and that's why you won't generally find me answering
questions about Core Data...).
So where should a newbie get some help. I'm hoping at the forum
like this.
Yes, *but* the people here won't lead you by the nose to your
answer. Nobody has time to do that for all of the people who might
post questions to the list, so sometimes you'll get a fairly terse
answer if you ask a question that (a) is something you could have
found for yourself, (b) is obvious, (c) is the same question that ten
other people just asked, (d) doesn't make sense, etc. etc.
So even though the answer was terse, remember that mmalc (who is a
volunteer) did give you an answer and also tried to point you to
somewhere where you could find more information.
Kind regards,
Alastair.
