推荐答案
Python 产生的输出控制台写入程序输出流 sys.stdout(正常输出)和 sys.stderr(错误输出，例如异常回溯).在这种情况下，我们将使用 stdout
The output consoles produced by Python are written to the program output streams sys.stdout (normal output) and sys.stderr (error output, such as exception tracebacks). In this case we will use stdout
class Stream(QtCore.QObject):
newText = QtCore.pyqtSignal(str)
def write(self, text):
self.newText.emit(str(text))
class Window(QtGui.QMainWindow):
def __init__(self):
super(Window, self).__init__()
self.setGeometry(50, 50, 500, 300)
self.setWindowTitle("PyQT tuts!")
self.setWindowIcon(QtGui.QIcon('pythonlogo.png'))
self.home()
sys.stdout = Stream(newText=self.onUpdateText)
def onUpdateText(self, text):
cursor = self.process.textCursor()
cursor.movePosition(QtGui.QTextCursor.End)
cursor.insertText(text)
self.process.setTextCursor(cursor)
self.process.ensureCursorVisible()
def __del__(self):
sys.stdout = sys.__stdout__
