Question

学习如何使用tkinter时，我遇到了一个我不理解的错误，因为这对我来说真的没有意义。它指出选项“ -menu”未被识别，但是...我不使用它？

感谢您的阅读和帮助！

import tkinter as tk


LARGE_FONT = ('Verdana', 12)


class CofBTC(tk.Tk):

    def __init__(self, *args, **kwargs):

        tk.Tk.__init__(self, *args, **kwargs)
        container = tk.Frame(self)

        container.pack(side='top', fill='both', expand=True)

        container.grid_rowconfigure(0, weight=1)
        container.grid_columnconfigure(0, weight=1)

        self.frames = {}

        frame = startPage(container,self)

        self.frames[startPage] = frame

        frame.grid(row=0, column=0, sticky='nsew')

        self.showFrame(startPage)

    def showFrame(self, cont):

        frame = self.frames[cont]
        frame.tkraise()

class startPage(tk.Frame):

    def __init__(self, parent, controller):

        tk.Frame.__init__(self, parent, controller)
        label = tk.Label(self, text = 'Start Page', font = LARGE_FONT)
        label.pack(pady=10, padx=10)

root= tk.Tk('TestTkinter')

app = CofBTC()
app.mainloop()

编辑：被要求提供完整的错误消息，所以就在这里（我不太了解，因此出于某种原因，我没有想到某些人确实理解了这些笑声）： >

TclError: unknown option "-menu"`

Answer 1

问题是因为您将controller发送到Frame

tk.Frame.__init__(self, parent, controller)

它不知道如何处理这个意外元素

您需要

tk.Frame.__init__(self, parent)

顺便说一句：：如果您从tk.Tk-class CofBTC(tk.Tk)继承，则不需要root= tk.Tk('TestTkinter')，因为tkinter应该只使用一个窗口创建与Tk()

在Python 3中，您可以使用super()

    #tk.Tk.__init__(self, *args, **kwargs)
    super().__init__(*args, **kwargs)

和

    #tk.Frame.__init__(self, parent)
    super().__init__(parent)

TclError：在python3.7上使用tkinter的未知选项'-menu'
