wxNotebook on a wxPanel.. how?

[phark52]

I have a wxFrame. On it is a wxNotebook, the Notebook ctrl has 5 tabs
(Each one is a wxPanel.) On one of the tab pages (panels) I want to add
another notebook ctrl. I get no errors but nothing shows up on the
panel.. why is that? If I add a button or checkbox to the sizer on that
panel, it shows. A notebook ctrl just isn't visible. The code is below:

I checked and AddPage() returns True
Weird thing is I can see a little bit, like the corner of a button
where the wxNotebook is supposed to start.

class TabPage(wxPanel):
def __init__(self, parent):
wxPanel.__init__(self, parent, -1)

self.nb = wxNotebook(self, -1)
self.nb.AddPage(wxPanel(self.nb, -1), "Settings")

sizer = wxBoxSizer(wxHORIZONTAL)
sizer.Add(self.nb(self))
self.SetSizer(sizer) 
self.Layout() 
self.Fit()

The above code I pasted was not correct. I pasted an older version. The
sizer.Add() line should of been sizer.Add(self.nb) -- omit the (self).

but I fixed the problem. I had to change that same line to
sizer.add(self.nb, 1, wxEXPAND|wxALL)

Writing C readable bitfield structs?

[phark52]

How would I go about writing a bitfield that can be read by my C app? I
want to pack a few bools into one int.

I know an extended module exists (npstruct) which helps you do this but
I want to do it manually or using one of the standard modules.

struct S {
unsigned int a : 1;
unsigned int b : 1;
unsigned int c : 1;
unsigned int d : 1;
};

fread(from file (file written by Python app) into an instance of struct
S)
then I want it to be used as follows:
if (instance.a) f();
if (instance.b) g();
struct S comes out to 4 on my arch. I do not want to use a new int for
every member of struct S.

Anyone have any idea?
