[PyQt] modules, nameSpaces, and Wizards

[James Polk]

Good Day to All,

I'd like to engage the heavy weight gurus out there,
but anyone is welcome to respond,..
(Apologies for the long-winded email, but difficult
to accurate explain)

Though not new to software development, I'm still a bit
of a green horn in PyQt, and in my usual habit of running 
before I learn to walk, I've began to code the fun things
and glossed over a few foundation basics, one of which
is modules and namespaces.  I'm used to using these constructs
from other languages and applications, and I had gleaned
how to use these, albeit at a novice level.  But now, I've
got a need where I need to do something kinda' fancy, but
not covered in any of the books I have, nor after web searching,
so here is the dilemma...

I had created 3 separate PyQt apps, each having the same 
development path...

from Designer ----> AAA.ui
from pyuic.py ----> ui_AAA.py

then in my main program, I do the import

import ui_AAA.py as AAX

then write the rest,etc....


So, I was tasked to string these 3 apps togther into a 
continuing sequence,..so I looking at QWizard, and I've
been successful at coding a very small, bare-bones PyQt
program that puts in of the three UIs into the 1,2,3 nature
of the wizard.  Near the top of this program are

import ui_AAA.py as AAX
import ui_BBB.py as BBX
import ui_CCC.py as CCX

My Main Function looks like this:

class MainWizard(QtGui.QWizard):
def __init__(self, parent=None):
QtGui.QWizard.__init__(self, parent)
self.topWObject = parent
self.setWizardStyle(1)
self.setGeometry(400, 200, 650, 750)

self.setPage(0,Step1_CreateAsset_Dialog(self))
self.setPage(1,Step2_UpdateData_dialog(self))
self.setPage(2,Step3_Publish_dialog(self))

and the "Step 1" (Page0) functions is as follow:

class Step1_CreateAsset_Dialog(QtGui.QWizardPage,Wizard_CreateAsset):
def __init__(self, parent=None):
QtGui.QWizardPage.__init__(self,parent)
Wizard_CreateAsset.__init__(self)
self.setupUi(self)

and the other functions for steps 2 & 3 (Page1 & Page2) are essentially
identical...This all works,...and I am much relieved ;-) 
But here's my problem...

Each of these underlying 3 apps, have their own "main" function,
which I can copy&paste in easy enough,...but also each of them
have kinda' long supporting functions.  After a test, I found
I could "brute force" it, and copy&paste the entire program
into (and under) the stepX function above,...but rather than
do that,...isn't there a way, where I can do another "import"
statement and *link* the old-way program into the new-way (wizard) one?

>From other work,...I know that I could do

    import main_AAA.py as AAA_Main

and in subsequent statements,...use the namespace like

    self.whatever(AAA_Main.whatever())

etc,etc...which works in the initial "class" definition function,
but I can't find the right syntax or something to pull in all the
other functions.

I copied 
    main_AAA.py 
to 
    stripped_main_AAA.py

and stripped out everything except the functions,...and tried to
import it back into the wizard main as:

    import stripped_main_AAA.py as AAA_stm

but calling the functions inside "stripped_main_AAA.py" using
the nameSpace prefix "AAA_stm" doesn't work...the first thing
it complains about are graphic elements.

in stripped_main_AAA.py, there's

    self.WarningLabel

but addressing that element back in the Wizard proram as

    AAA_stm.WarningLabel
or
    AAA.WarningLabel

neither works....


So, strategically thinking,...what's the best way to achieve this kind 
of program/module sharing/linking?

Any thoughts, suggestions, advice, or words of wisdom, is mostly greatly
appreciated,
Thank you,
-James
