Problem solved. I was not properly passing the master widget reference
in my frame classes
class MyWidget(Frame):
def __init__(self, master, columns,rows, trace_write=None):
Frame.__init__(self) # here's my mistake
...
...
...
should have been:
class MyWidget(F
I'm still hammering away, and have found that when I change:
class testWidget(Frame):
def __init__(self, master):
Frame.__init__(self)
self.createWidgets()
def createWidgets(self):
Label(self,text="testWidget").grid()
to:
def __init__(self, master):
