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)
...
