Why Does .Hide()ing and .Show()ing Panels in wxPython Result in the Sizer Changing the Layout?

Question

As referenced in my previous question, I am trying to make something slightly wizard-like in function. I have settled on a single frame with a sizer added to it. I build panel

Answer 1

I think I figured it out. Instead of calls to the Show and Hide methods of the panels, you need to call the Show and Hide methods of the root sizer:

self.Show()

becomes

self.GetParent().GetSizer().Show(self)

...and so on.

Also, after each call, you need

self.GetParent().GetSizer().Layout()
