Well, I've found a partial answer for a slightly less complicated
megawidget:

>>> nbpage1 = notebook.add ('first',label="First")
>>> nbpage2 = notebook.add ('second',label="Second")
>>> notebook.pages()
[<Tix.TixSubWidget instance at 0x00BAB940>, <Tix.TixSubWidget instance
at 0x00BA
BDF0>]
>>> notebook.subwidget_list
{'nbframe': <Tix.TixSubWidget instance at 0x00BABC38>, 'second':
<Tix.TixSubWidg
et instance at 0x00BABDF0>, 'first': <Tix.TixSubWidget instance at
0x00BAB940>}
>>> nblab = Tix.Label(nbpage1,text="Test First Tab")
>>> nblab.pack()
>>> nbbtn = Tix.Button(nbpage2,text="Test Second Tab")
>>> nbbtn.pack()
>>> nbbbox = Tix.ButtonBox(nbpage1)
>>> nbbbox.add ('nbbxb1',text='Yeah!')
'.12236560.nbframe.first.12237760.nbbxb1'
>>> nbbbox.pack()
>>> nbbbox.add ('nbbxb2',text='Nah...')
'.12236560.nbframe.first.12237760.nbbxb2'
>>> nbp2lab1 = Tix.Label(nbpage2,text='This is the second most\ncomplicated widg
et that has been mastered\nCome over some day maybe play poker')
>>>
>>> nbp2lab1.pack()

I still don't have ListNoteBook widgets sussed, but I'm on the road.
