David,
I am reposting this to the list to let other people provide you with a
probable better answer.
I'm not really gui-oriented, so I might have a narrow sight of the problem.
I downloaded and tried the easygui script. Looks like your actual
problem is it's lack of support for value/text pairs. So, depending on
your actual needs I'd consider using a "less than easy" library.
If you still want/need to stick with this one, you will have to pass the
index as part of the label and parse the answer afterwards. You could do
something like:
# starts code:
import easygui
def getIndex(choice):
return int(choice.split('.', 1)[0]) - 1
choices = ['Personality Test', 'Political Test', 'Driving Test', 'Icules
Test']
labels = ["%s. %s" % item for item in enumerate(['dummy'] + choices)][1:]
answer = easygui.multchoicebox(
message="Pick the test(s) you would like to run from the list
below.",
title="Validation Tests",
choices=labels
)
tests = [getIndex(item) for item in answer]
# ends code
After this, the variable "tests" holds the list of the chosen indexes,
that you can use to get any value from the actual objects you had in
your original list.
A much simple approach (given the fact that you will probably never have
two identical labels) is to simply use list.index, but given
easygui.multchoicebox's nature, you will first have to sort your objects
labels aphabetically:
# starts code:
import easygui
labels = ['Personality Test', 'Political Test', 'Driving Test', 'Icules
Test']
labels.sort()
answer = easygui.multchoicebox(
message="Pick the test(s) you would like to run from the list
below.",
title="Validation Tests",
choices=labels
)
tests = [labels.index(item) for item in answer]
# ends code
Notice that these indexes refer to the labels order, not necessary your
original objects'. Supposing you initially had a list of dictionaries,
you will have to sort that list by the labels first. E.g.:
>>> objects = [{'label': 'Personality Test', 'cargo': 'something'},
{'label': 'Political Test', 'cargo': 'something'}, {'label': 'Driving
Test', 'cargo': 'something'}, {'label': 'Icules Test', 'cargo':
'something'}]
>>> from operator import itemgetter
>>> objects.sort(key=itemgetter('label'))
>>> objects
[{'cargo': 'something', 'label': 'Driving Test'}, {'cargo': 'something',
'label': 'Icules Test'}, {'cargo': 'something', 'label': 'Personality
Test'}, {'cargo': 'something', 'label': 'Political Test'}]
>>> labels = [obj['label'] for obj in objects]
>>> labels
['Driving Test', 'Icules Test', 'Personality Test', 'Political Test']
HTH,
