I changed the version of wxWidgets and wxPython to the latest from 2.8.12 and the application can’t start after that.
The problem:
self.m_Auinotebook is of type wx.aui.AuiNotebook .
The call :
self.m_Auinotebook.AddPage( self.m_panel6, u"Text", False, wx.Bitmap( u"res/text.png", wx.BITMAP_TYPE_ANY ) )
throws the exception:
<<<
File “C:\Python27\lib\site-packages\wx-3.0-msw\wx_core.py”, line 13623, in AddPage
return _core_.BookCtrlBase_AddPage(*args, **kwargs)
TypeError: in method ‘BookCtrlBase_AddPage’, expected argument 5 of type ‘int’
swig/python detected a memory leak of type ‘wxPyXmlSubclassFactory *’, no destructor found.
I have found a similar case in this old message of 08.02.2012 (quoted at the end of this mail), so this was an old bug.
Another call brings the same result:
self.m_logsAuinotebook.AddPage( self.m_panel9, u"Log", False, wx.NullBitmap )
( The code is generated by wxFormBuilder. )
wxPython DEMO works only because instead of C++ version of aui it uses wxPython version:
import wx.lib.agw.aui as aui
So as workaround it is possible to replace :
import wx.aui
with:
#import wx.aui
import wx.lib.agw.aui as aui
wx.aui = aui
Are there any better solution?
Otherwise it is needed to patch the code generated by wxFormBuilder just to plaster this bug.
Thanks!

Big quote of an old mail:
<<<
Subject: Re: [wxPython-users] Re: GenericDatePickerCtrl crashes
[wxWidgets] 2.9.3.1 breaks the .AddPage method of AuiNotebook. The
statement:
self.auinbDataLists.AddPage( self.pnlAllVehicles, u"Vehicles",
False, wx.NullImage )
works in 2.9.2.4 but in 2.9.31 generates this exception:
TypeError: in method ‘BookCtrlBase_AddPage’, expected argument 5
of type ‘int’
If I eliminate that last argument (wx.NullImage), it works. (FYI,I think FormBuilder creates the wx.NullImage argument.)
The AuiNotebook is now derived from BookCtrlBase instead of
reimplementing all the basic functionality itself. AddPage in
BookCtrlBase looks like this:
virtual bool AddPage(wxWindow *page,
const wxString& text,
bool select = false,
int imageId = -1);
There is still the AddPage in AuiNotebook like the following, but
apparently the one in the base class is taking precedence there…
bool AddPage(wxWindow* page,
const wxString& caption,
bool select = false,
const wxBitmap& bitmap = wxNullBitmap);
