Hello,
the following error message is printed when resizing a wxListCtrl
combined with wxListCtrlAutoWidthMixin. This happens only
when a wxImageList is NOT associated with the wxListCtrl.
When a wxImageList is associated with wxListCtrl everything
works fine.
I use wxPython 2.4.0.7 running on python 2.2.1

Is it a virtual list control? If so, then you need to always provide a OnGetItemImage method, even if it just returns -1. If not, then it is a bug. Please distill it down to a small sample that shows the problem.

Arye, I had this problem when I moved from GTK/Linux to MSW. It's a
platform inconsistency and perhaps even an MSW-bug. I solved it by
adding this to my subclass of ListCtrl:
def OnGetItemImage(self, item):
return 0

The docs explicitly state that you don't have to override that method
*if* you don't have an image list associated with the control. And
that's the behavior on GTK/Linux. Only on MSW did I have to provide
that method, so that seems like a bug.
fyi,
