So you think PythonCard is old? Here's new wine in an old bottle.

For serveral years, I have been looking for a way to migrate away from
desktop GUI/client-server programming onto the browser based network
computing model of programming. Unfortunately, up until recently,
browser based programs are very limited - due to the limitation of
HTML itself. Eventhough PythonCard hasn't keep up with the latest
widgets in wxpython, the programs so created still works a lot better
- until now.

If you look at programs at some of the major sites these days - like
Google calendar, Netflix, blockbuster, and so forth - you would
undoubtedly notice that the quality of the programs are pretty much at
par with the desktop programs we use everyday. Since the curious mind
wanted to know how these programs are done, I started investigating
and found out that what a difference a few years have made to
Javascript - the once much hated beast of the Internet age - and
during my search for perfection, I found Qooxdoo (http://
qooxdoo.org/).

Qooxdoo is a Javascript toolkit that sits on top of Ajax. Take a look
at some of the *impressive* widgets
at http://demo.qooxdoo.org/current/showcase/#Form.

So, what's that got to do with Pythoncard? Read on.

After trying for a few days learning Qooxdoo, my head really really
hurts. Getting too old to learn this stuff, I was mumbling.

Then I looked some more. I found QxTransformer (http://
sites.google.co m/a/qxtransformer.o rg/qxtransformer/Home) which is a
XSLT toolkit that creats XML code that invoke qooxdoo.

So, what's that got to do with Pythoncard? Read on.

After trying for a few days learning QxTransformer, my head really
really hurts. Getting too old to learn
this stuff, I was mumbling.

I want Pythoncard.

Damn Pythoncard! Once you got hooked, everything else looks
impossibly complicated and unproductive.

But then I looked closer. It turns out the XML file created by
QxTransformer is *very* similar in structure when compared to the
resource files used in PythonCard. Since there are no GUI builders
for QxTransformer, and I can't affort to buy the one for Qooxdoo
(Java! Yuk!), I decided to roll up my sleeves, took the Pythoncard's
Layout Manager and modified it and created my own "Poor Man's Qooxdoo
GUI Layout Designer".

The result? See the partially completed application at:

http://test.powersystemadvisors.com/

and the same application running from the desktop:

http://test.powersystemadvisors.com/...HelloWorld.jpg

It shouldn't be long before I can fill in the gaps and have the GUI
builder maps the rest of the Pythoncard widgets to Qooxdoo widgets.
Once I've done that, I can have the same application running from the
desktop, or from the browser. And it shouldn't take more than minutes
to create such applications.

Welcome to the modernized world of Pythoncard!!!

Do they work? (Not all of them will work - some requires a database)
Yes, the examples work. Just the resourceEditor. py and the
layoutEditor.py in the distributed version and your modified
layoutEditor.py don't.

Ok, here is how it works for me: copy all the *.rsrc.py from the
modules subdirectory to the parent directory. This works for the
standard resourceEditor folder and your custom layoutEditor folder.
What the heck. Now I can deal with more productive things...
Mmmmmm...this is a Mac thing.

John, you are the man
during my search for perfection, I found Qooxdoo (http://qooxdoo.org/).

...

I found QxTransformer (http://sites.google.com/a/qxtransfor...ansformer/Home) which is a
XSLT toolkit that creats XML code that invoke qooxdoo.
Qooxdoo is indeed really impressive. But I read that YAHOO will serve
the javascript files for you from their CDN when you use YUI, for
free, and that's no peanuts, so I wonder, did you find anything at all
like that that could be used with YUI?

I have evaluated XForms, Laszlo, Flex, ZK, ... but I have to say
QxTransformer is the cleverest solution I have found so far (thanks to
you). I love it.

I want Pythoncard.
I feel with you

Thanks!

Sorry but I don't know any of this. I am pretty new to web
programming.

I have done quite a bit of work to improve things. We are now
officially calling the project PyQooxCard. See:

http://sites.google.com/a/qxtransfor...ansformer/Home

I put together my first app which took less than a day. Not bad
because there are 36 screens, and over 100 data fields. See:

http://epc.powersystemadvisors.com

3 cheers to PythonCard.

Thanks!

Have you shown this stuff to the google AppEngine folks!
Thats being touted as the thing that'll make web-2 easy

but you have to write code (Python) which will turn off 99% of
possible users.

What made Hypercard really great (and Supercard on DOS, and the new
clones like Revolution) is that it was a drag-n-drop GUI designer, it
"built-in" the data storage (persistence layer is what we call it now)
it was INTEGRATED, (you only had to get the one thing, not heinz-57-
bloody-pieces) and it used an easily-readable interpreted programming
language.

App-Engine has the persistence, and the integration, its missing the
others and without them it'll never be great.

call those guys, they need you!
I need your stuff on their infrastructure. THAT would be worth a case
of champagne.

Google App Engine is _only_ focused on providing a framework for
scaleable apps, the GUI end is left entirely up to the developer (and
really _shouldn't_ be integrated at that level, IMO).

There's nothing preventing you from building something on top of GAE
that does what you want; using their AJAX Libraries API is a good
place to start: http://code.google.com/apis/ajaxlibs/

I also like that it does not force you to use...
