Question

我使用Tkinter在Python 3.5中创建了一个多线程程序。

当我启动程序时，它不会给出任何错误，但它会形成一个完全白色的窗口。我也尝试停止GUI线程，但程序没有退出...

感谢您的回答。

class StartGUI(threading.Thread):

        self._stop = threading.Event()

    def run(self):
        self.GUI = GUI(None)
        self.GUI.title('Eve 3.0')
        self.GUI.mainloop()

    def stop(self):
        self._stop.set()

    def stopped(self):
        return self._stop.isSet()

class GUI(Tk):

    def __init__(self, parent):
        Tk.__init__(self, parent)
        self.parent = parent
        self.initialize()

    def initialize(self):
        self.grid()

        self.outTxt = Text(self, height=5)
        self.outTxt.grid(column=0, columnspan=3)

        self.eraseButton = Button(
            self, bg='#424242', fg='white', text='Erase', command=self.eraseInput)
        self.inTxt = Entry(self, bg='#424242', fg='white')  # , height=2)
        self.submitButton = Button(
            self, bg='#424242', fg='white', text='Submit', command=self.submitInput)

        self.eraseButton.grid(column=0, row=1, sticky='EW')
        self.inTxt.grid(column=1, row=1, sticky='EW')
        self.submitButton.grid(column=2, row=1, sticky='EW')

    def eraseInput(self):
        self.inTxt.delete(0, END)

    def submitInput(self):
        input = self.inTxt.get()
        self.inTxt.delete(0, END)
        print(input)

if __name__ == '__main__':
    GUIThread = StartGUI()
    GUIThread.start()
    GUIThread.stop()
    stopped = GUIThread.stopped()

编辑：窗口是完全白色的，即使操作系统特定的覆盖层也不会呈现......
