The difficulty here is that you want to pass information to the form before the form instance is created. Perhaps you could create a classmethod in your form class that would accept these additional parameters, and store them in class attributes. Then they could be retrieved and acted upon in the __init__() of the form. Something like:

(in the form class)

@classmethod

def storeSetupValues(cls, projectName=None, dataFile=None, ...):

cls.projectName = projectName

cls.datafile = dataFile

...

def __init__(self, ...):

super(MyFormClass, self).__init__(...)

self.doExtraSetup()

def doExtraSetup(self):

self.readDataFile(self.datafile)

...
