I was wondering about this, so I did quite a bit of google searches, and came up with the SetWrapMode(self, mode) function. However, it was never really detailed, and there was nothing that really said how to use it. I ended up figuring it out, so I thought I'd post a thread here and answer my own question for anyone else who is wondering how to make an stc.StyledTextCtrl() have word wrap.
It would be more maintainable to use the constants stc.WRAP_NONE, stc.WRAP_WORD, stc.WRAP_CHAR and stc.WRAP_WHITESPACE instead of their numerical values.
