[PySide] QTextStream() writes empty string

[Tim Doty]

I finally have narrowed down an issue encountered with PySide 1.0.8 (yeah, I just saw the 1.0.9 announcement, but didn't see anything that looked like this). In short, a QTextEdit() based text editor I wrote stomps on files whenever it saves (writes an empty string). It worked fine in previous versions of PySide.

What appears to be happening is that .toPlainText() returns a unicode object and for QTextStream's overloaded << operator a unicode string results in an empty file.

So... how is QTextStream supposed to be used for writing unicode? (if a call to .setCodec() using 'UTF-8' is put in before the string output the same behavior continues so, no, that isn't it)

#!/usr/bin/env python
# -*- coding: utf-8 -*-
from PySide.QtCore import *

myFile = '/tmp/test.txt'
strings = ['Hello World\n', u'Goodbye, Cruel World\n']

for string in strings:
    print 'saving %s' % string
    fh = QFile('/tmp/test.txt')
    if not fh.open(QIODevice.WriteOnly):
        raise IOError, fh.errorString()
    stream = QTextStream(fh)
    stream << string

    fh = QFile(myFile)
    if not fh.open(QIODevice.ReadOnly):
        raise IOError, fh.errorString()
    stream = QTextStream(fh)
    while not stream.atEnd():
        print stream.readLine()
