ComboBox and Set() command; do I missunderstand the wxPython in Action book?

Hi,

I am a bit confused about the ComboBox. I would like to replace the
items of it and in the wxPython in Action book it says on page 222 that:

  "Since wx.ComboBox is a subclass of wx.Choice, all of the methods of
  wx.Choice can be called on a combo box, as displayed in table 7.14."

Now table 7.14 says that it lists the methods of a list boxes and among
others there is the Set() command listed.

I tried it but I am getting an AttributeError exception:

    [...]
    File "e:\pj\view.py", line 268, in __init__
      cb.Set(['hello', 'day',])
  AttributeError: 'ComboBox' object has no attribute 'Set'

The confusion comes in when I look in the wxPython documentation at
wxPython.org. There it shows that the

- ComboBox is derived from ItemContainer and Control
- Choice as well as ListBox are derived from ControlWithItems and
  Control

When I look for the Set() member function, that it is actually part of
ListBox and hence cannot be used in Choice.

Am I understanding the book wrong? It seems to me that it is not right
what is said there about the ComboBox?

Thanks for any clarification.

Cheers,

Guenter
