[Pythoncard-users] Brain Fade

Evening all,

Its late, but I can't find any examples of what I want to do anywhere. 
This is a fairly frequent occurrence in the world of relational 
databases and I've been scratching my head trying to figure out how to 
represent it in PythonCard.

Enough teasing, I have a table which contains keys and descriptions and 
I want to display the available descriptions in a 'choice' widget. Which 
is fairly easy. But when the user selects an element in the choice 
widget I want my code to know the corresponding key value. Is there any 
way to associate multiple items (say tuples?) with a choice widget?

At the moment I'm returning the key-description pairs into a dictionary, 
so of course it would be nice to just get the key from the description 
value but I don't know of a way to do this in ordinary Python, unless I 
am being more of an idiot than usual.

I don't think I can associate multiple values with each item in 
PythonCard (or wxPython for that matter) so I probably need to do this 
in my program.

But, and this is a big but, I don't want to have to iterate through all 
of the available key-description pairs to find the key I'm looking for 
based on the value from the choice widget.

Any suggestions?

Regards,
Andy
