Strings, Unicode, and ListCtrl

wxPython Users

Hi All,

I'm migrating an application to the latest wxPython version.

By incident I got the Unicode version which complains when I use ListCtrl's SetStringItem() method because the string contains an accented character (not in range(128)). The non-Unicode version doesn't complain and shows the correct character.

My questions:
- Is this how it is supposed to be?
- How can I make it work on both Unicode and non-Unicode?

Windows XP/Python 2.3.4/wxPython 2.5.2.7

Thanks all for telling me to RTFM. I did.

I'm still puzzled, as I only have errors on accented characters in a ListCrtl w/Unicode.
The same string goes without a problem into a StaticText.

Yes. In the unicode builds the default Python encoding is used to convert strings to unicode objects whenever a wxString is expected by the C++ code. Since your default encoding is probably 'ascii' then it fails.

- How can I make it work on both Unicode and non-Unicode?

There are some options:

* Change the default encoding for your python.

* Pass all strings through a function that does something like this pseudo code:

  if obj type is string and 'unicode' in wx.PlatformInfo:
    obj = decode to unicode object with some appropriate encoding
  return obj
