Looking at the lines below
As related to the code I posted above.
I believe this code will allow me to instantiate the class
MyDialog, wait until the window is destroyed and then
continue on my merry way.
root = Tk()
d = MyDialog(root)
root.wait_window(d.top)
Now if I pass an instance of Unamepword into the constructor of
MyDialog(unamepword) , I can modify uStr and pWord in MyDialog and
the local copy will get updated.
Correct?
class Unamepword:
##
## class to hold user name and pWord for Database
uName = None
pWord = None
def __init__(self, uStr, pStr):
self.uName = uStr
self.pWord = pStr
Many thanks for your attention to this matter.
