Strange Sizer Answer...

Hello NG,

I am working on a medium-sized wxPython thing and, while I am becoming crazy for other problems, I get sometimes this kind of messages:

File “C:\Python24\Lib\site-packages\wx-2.6-msw-ansi\wx_core.py”, line 11491,
in IsShown
return core.SizerItem_IsShown(*args, **kwargs)
wx._core.PyAssertionError: C++ assertion “wxAssertFailure” failed in …\src\common\sizer.cpp(458): unexpected wxSizerItem::m_kind

???

Does anyone know what this message could mean? Thanks a lot for every suggestion…

Andrea.

It means that IsShown was called on an item that is not referencing a Window, a Sizer or a spacer. Not sure how that could happen though...

Maybe an item was added and IsShown was called before a Layout()? Try
sizer.Layout() before calling IsShown().
