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!!!

So far, I have the following widgets working:

window, button, checkbox, static text, static box, list, combobox,
spinner, radio button group

Shouldn't be long before the following works:

static line, image, image button, choice.

Actually, I was asking what operations you chose to support in 'static
text'. Additional Python methods of strings could be made to work on
them.

John,

This is very interesting! Please do make this available. I love
PythonCard, but I am doing mainly web programming these days.

I will mention this on my next podcast. Can you do a slider?

Hey, that's really neat !

I remember dabbling in Pythoncard in the early days, some years ago, it was
a very interesting project. I gave it up eventually, partly because it
seemed somewhat abandoned (I see it's still stuck in 2006 ?), but mostly
because the wxPython dependency was either unavailable or too hefty for the
sort of machines I was interested in using it on (a Sharp Zaurus then, now
Nokia Internet tablets). Since then I've been doing web apps instead,
hosted and used on the devices themselves.

So using Pythoncard as a designer for web apps, of course that rings a
bell...

Do you have any idea of the computing requirements of Qooxdoo and
QxTransformer, compared to a native Pythoncard app ? I wonder if your stuff
would run acceptably on today's mobile platforms (the Nokias have a Firefox
derivative that is reasonably competent at javascript), and would give it a
try if it's not too arcane.

Do keep us posted !

TIA,
fp

Not sure if Qooxdoo supports slider yet. I have to ask.
