        button_back = Button(window,text="Sluiten",command = self.mainWindow())
        button_back.pack()
    def quitAll(self):
        '''Close all the current windows'''
        self.lijn_window.quit()
        self.app.quit()
    def lijnritten(self):
        ''' Make the lijnritten window'''
        self.app.quit()
        self.lijn_window = Tk()
        self.lijn_window.title("lijnritten")
        self.endButton(self.lijn_window)
        self.finish(self.lijn_window)
main(None)

Answer 1

当您链接命令时，不要使用 () 所以 command=self.action，就像这样。此外，这一行似乎给您带来了一些麻烦 self.quitAll()...不确定您要用它做什么，但这是我的两分钱。
