[IronPython] newbie getting started problem

Tue Aug 10 15:13:03 CEST 2010

Hi I've been following the getting started examples here:
http://blog.jimmy.schementi.com/2010/03/pycon-2010-python-in-browser.html

I've hit a newbie ignorance problem as soon as I've tried to go 'off-piste'
with this (below):

(The debug print statement shows up in the repl console and there are no
exceptions - but no gui shows up)

(In previous Python/Qt contexts I would have been concerned about my script
variables going out of scope at the end of the run and GUI artefacts being
garbage collected - but the examples I'm copying from don't seem to need any
special treatment to avoid garbage collection?).

Any help much appreciated - and by the way - after over 20 years as a
professional programmer - this is about the most exciting technology
combination I've come across.

Pete
