上篇文章的将命令行输出重定向到UI界面之后，在关闭UI界面时候会报错

has no attribute of flush in python或者

PyQt: RuntimeError: wrapped C/C++ object has been deleted

解决方案是在命令行输出重定向到的类里面添加一个函数:
 

class ButtonOne(QThread):
    _signalForText = pyqtSignal(str)
 
    def __init__(self):
        super(ButtonOne, self).__init__()
 
    def write(self, text):
        self.signalForText.emit(text)
 
    def run(self):
 
        for i in range(15):
            time.sleep(1)
            print(i)
        print('end')
 
    @property
    def signalForText(self):
        return self._signalForText
    
    def flush(self):
        pass

这样就可以解决。

添加的函数为:

def flush(self):
    pass
