PyQt把控制台输出打印到textEdit（控件）上碰到的问题

[lukeqi]

这是我从Stack Overflow上找的代码，就是PyQt把原本terminal输出的语句转打印到控件上。

不过中文是乱码，亲们有没有人懂怎么把如下的语句正常打印出中文啊？谢谢！

    from PyQt4 import QtCore
    
    class EmittingStream(QtCore.QObject):
    
        textWritten = QtCore.pyqtSignal(str)
    
        def write(self, text):
            self.textWritten.emit(str(text))


    # Within your main window class...
    
    def __init__(self, parent=None, **kwargs):
        # ...
    
        # Install the custom output stream
        sys.stdout = EmittingStream(textWritten=self.normalOutputWritten)
    
    def __del__(self):
        # Restore sys.stdout
        sys.stdout = sys.__stdout__
    
    def normalOutputWritten(self, text):
        """Append text to the QTextEdit."""
        # Maybe QTextEdit.append() works as well, but this is how I do it:
        cursor = self.textEdit.textCursor()
        cursor.movePosition(QtGui.QTextCursor.End)
        cursor.insertText(text)
        self.textEdit.setTextCursor(cursor)
        self.textEdit.ensureCursorVisible()

估计是编码问题。找到问题的办法是顺着你的数据经过的地方，检查在那儿数据出了问题。就你的例子来说： print --> EmittingStream.write --> normalOutputWritten(self, text) --> cursor.insertText(text) 在每一步，检查type(text)（通过插入print或单步调试）.最后一步时，text应该是unicode string。

在print之前加一句： QTextCodec.setCodecForCStrings(QTextCodec.codecForName("utf-8"))
