Porting from GUI 4.0 -> 2.1

I had a recent request to port the SUnit Browser
(http://www.odellsoft.com/sunitbrowser) from Dolphin 4.0 to the free version
of Dolphin 2.1.  Having been a late convert to Dolphin, can anyone comment
in a general sense whether this port will be difficult?

The SUnit Browser has a model that executes the functionality of the
browser.  This model has no GUI dependencies and it ports pretty easily - I
used SIF to port it from VisualAge.  However, the GUI part is unique to each
platform.  So the real question becomes whether I can back port the GUI from
4.0 to 2.1 or whether it is essentially a do-over on the GUI.

Thanks in advance for any advice -

ListModel and ChoicePresenter have improved significantly in their support
for identity vs. equality.  There will no doubt be other snags due to things
that have been long-since fixed.

I'll admit that there's a part of me that would quote an hourly rate for the
effort :)   D4 is a great product, and very affordable, especially at the
low end.  Having better third-party support for D4 than the free version
might encourage some folks to pony up, which is good for OA and therefore
for all of us.  Just my $0.02 on the subject, and not at all meant to tell
you what to do.

Have a good one,

Bill

I too had second thoughts about the port, but it was a request from a
university in Uruguay that was using Dolphin Smalltalk 2.1 for a class.
Prior to that request, I had no intention of looking at 2.1.  Since it meant
introducing more folks to Smalltalk, I felt it might be worthwhile if it
wasn't too great an effort.  Perhaps Andy or Blair will want the contact
that e-mailed the request to me as they might offer them an educational
deal.

As far as the value and affordability of 4.0, I agree wholeheartedly!

That's getting to be a pretty good reason to do it; but, it might also be an
excellent project for a graduate student (if they have a grad school) or
even a couple of motivated students in the class.  You might simply file out
the code and leave the details to them.

The deal (unless I found an obsolete page) is:

   http://www.object-arts.com/EducationalPricing.htm

AFAIK, this is not linked - I remembered there was a page describing it and
guessed the URL.

Have a good one,

We are no longer offering this Educational Pricing deal. This link (although
the page is still present) shouldn't be referenced from  anywhere. Existing
registrations under the educational scheme are still valid, however.
