使用Tkinter和Python将同一框架内的两个不同类插入笔记本的问题

Question

我一直在尝试使用Tkinter和Python在同一框架内插入两个不同的类(在下面的"MyListbox"one_answers"Calculation"代码中)。实际上，我还没有收到任何来自我的电脑的报告，告诉我哪里错了。我的电脑什么都没显示，连一条信息都没有。你能帮我解决这个问题吗?

提前感谢。

代码如下:

import Tkinter
from Tkinter import *
from Tkinter import Tk, Text, BOTH, W, N, E, S
from ttk import Frame, Button, Label, Style
import Tkinter as tk
import ttk 
import tkFont

notebook = ttk.Notebook(root)
notebook.pack(fill=BOTH, expand=True)

    app2 = Calculation (stepOne)----> This is not working!
    root.mainloop()

Answer 1

您正在使用app2 = Calculation (stepOne)，这意味着您将具有相同父元素的不同小部件放置在相同的网格位置。在这种情况下的结果是，Tkinter根本不显示任何小部件。

但是即使用app2 = Calculation (stepTwo)改变它，你仍然有同样的问题与这两行代码:

self.Button = Button(text='Calculate',width=8,command=self.Calc)
self.Button.grid(row=9,column=2,padx=2,pady=3)

您没有设置任何父元素，因此它使用默认的Tk元素，并且出现了我之前提到的相同问题，但这次是根元素。

最后，我强烈建议您对每个模块只使用一个import语句，因为Tkinter和ttk对某些类使用相同的名称，如果您使用主题小部件或不使用，则会有所不同。

import Tkinter as tk
import ttk 
import tkFont
import tkMessageBox
import sys
import math
