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

Hi,

I am one of the two developers working on the xml-to-javascript
converter (qxtransformer) John has mentioned and we are thrilled that
our project has found a use in the PythonCard community.

However, we have a problem getting PythonCard to work on our Macs (Mac
OS 10.5 Leopard). We should probably be asking this on the PythonCard
help list, but since the list seems to be somewhat deserted (very few
posts) and John is active here and people seem to be using PythonCard,
maybe someone has an idea. It might be very simple and stupid - I have
never worked with python before.

I am using
- PythonCard 0.8.2 release on Leopard, which is copied by setup.py to /
Library/Python/2.5/site-packages
- John's layoutEditor package, (http://qxtransformer.googlegroups.com/
web/layoutEditor.zip)

PythonCard email list says that Leopard and PythonCard 0.8.2 seem to
like each other generally:

and I can get the examples working. However, when I start John's
modified layoutEditor.py, I get an empty window and the following
error is thrown:

no resource file for /Users/bibliograph/Programme/PythonCard/tools/
layoutEditor/multipropertyEditor

    f = open(filename)

there is a file PythonCard/tools/layoutEditor/modules/
multipropertyEditor.rsrc.py

When I resize the window, I get the following errors

Thanks for any pointers,
