Problem with a wx notebook

[faucheuse]

Hi there,

I've created a wx NoteBook in wich I set multiples panels in wich I
set one or more sizers. But nothing displays in the notebook,
everything is outside. I've been searching an answer for 2 days ><.
Can you help me plz ? Here is my code(with only one panel, to sum up
the code) :

class StreamingActivationDialog(wx.Dialog):
    def __init__(self, *args, **kwds):
        # begin wxGlade: StreamingActivationDialog.__init__
        kwds["style"] = wx.DEFAULT_DIALOG_STYLE
        wx.Dialog.__init__(self, *args, **kwds)
        self.bitmap_1_copy = wx.StaticBitmap(self, -1, wx.Bitmap("img\
\logo.png", wx.BITMAP_TYPE_ANY))
        self.labelDnD = wx.StaticText(self, -1, "Si vous avez déjà un
fichier d'activation, faite le glisser dans cette fenetre")
        self.keyBitmap = wx.StaticBitmap(self, -1, wx.Bitmap("img\
\key.bmp", wx.BITMAP_TYPE_ANY))
        self.conclude = wx.StaticText(self, -1, _("test"),
style=wx.ALIGN_CENTRE)

        ### Panel ###
        self.intro3_label = wx.StaticText(self, -1, "Envoyez un mail à
\nactivation at monmail.com\ncontenant le code :",style=wx.ALIGN_CENTRE)
        self.activationCode_label= wx.StaticText(self, -1,
"123456789", style=wx.TE_READONLY)
        self.copy2_Button = wx.Button(self, -1, "Copier dans le presse-
papier")
        self.copy2_Button.Bind(wx.EVT_BUTTON, PanelMail.onCopy)
        ##############

        self.note = wx.Notebook(self, wx.ID_ANY, style=wx.BK_LEFT,
size=wx.Size(100, 341))
        self.page3 = wx.Panel(self.note)

        imagelist = wx.ImageList(94, 94)
        bitmap1 = wx.Bitmap("img\\a.bmp", wx.BITMAP_TYPE_BMP )
        imagelist.Add(bitmap1)
        self.note.AssignImageList(imagelist)

        self.__set_properties()
        self.__do_layout()
        # end wxGlade

    def __set_properties(self):
        # begin wxGlade: StreamingActivationDialog.__set_properties
        self.SetTitle(_("Activation de FlashProcess"))
        self.SetBackgroundColour(wx.Colour(255, 255, 255))
        #self.linkProblem.SetForegroundColour(wx.Colour(0, 0, 0))
        # end wxGlade

    def __do_layout(self):
        # begin wxGlade: StreamingActivationDialog.__do_layout
        self.grid_sizer_1 = wx.FlexGridSizer(6, 1, 0, 0)
        self.grid_sizer_2 = wx.FlexGridSizer(1, 2, 0, 30)
        self.grid_sizer_1.Add(self.bitmap_1_copy, 0, wx.TOP|wx.BOTTOM|
wx.EXPAND, 10)


        ### Page 3 ###
        sizer = wx.BoxSizer(wx.VERTICAL)
        sizer.Add(self.intro3_label, 0, wx.BOTTOM|wx.ALIGN_CENTER, 5)
        sizer.Add(self.activationCode_label, 0, wx.BOTTOM|
wx.ALIGN_CENTER, 20)
        sizer.Add(self.copy2_Button, 0, wx.ALIGN_CENTER, 20)

        self.note.AddPage(self.page3, "", False, 0)

        self.Bind(wx.EVT_TOOLBOOK_PAGE_CHANGED, self.OnPageChanged)
