problem extending tkSimpleDialog.Dialog

[William Gill]

I have created a widget that extends Frame() and contains labels, 
checkboxes, and entrys.  I am trying to use tkSimpleDialog.Dialog to 
create a modal display of this widget, but am running into some 
(addressing) problems.  My widget displays in the parent widget, not the 
tkSimpleDialog.Dialog?  I hope this snippet is enough to help, as my 
actual code is really too hard to follow.

class showtestWidget(tkSimpleDialog.Dialog):
     def body(self,master):
       Label(master,text="showPhoneNums").grid()
       testWidget(self).grid()

class testWidget(Frame):
     def __init__(self, master):
       Frame.__init__(self)
       self.createWidgets()
     def createWidgets(self):
       Label(self,text="testWidget").grid()

When the parent script instantiates showtestWidget() it should create a 
transient dialog containing a label with the text "showPhoneNums".  It 
does, but the label containing the text "testWidget" is being created in 
the parent widget, not the dialog.

It seems obvious to me that I'm addressing the wrong parent somehow, 
since the label (probably the testWidget) is being created, but in the 
wrong place.

I tried changing   testWidget(self).grid() to 
testWidget(master).grid(), just to see if that helped, but it made no 
difference.

Can someone show me where I went wrong?
