If I am understanding what you want, here is how I replace one window 
with another.

 From window A (which calls itself main) I call the child passing in 
itself as a parameter, something like:

self.child = B(self.main)
self.main.hide()

Then from B (which refers to A as parent and itself as main) in 
__init__() I call:

self.posx, self.posy = self.parent.get_position()
self.main.move(self.posx, self.posy)
self.main.show()

Then when I am done with B and want to replace it with A I do this from B:

self.main.hide()
self.parent.show()
self.main.unrealize()

That is how I do it and it seems to work well.
