使用Tkinter和Python在同一個框架內插入兩個不同類到筆記本中的問題

Question

我一直試圖在Tkinter的同一個框架內插入兩個不同的類（在「MyListbox」和「Calculation」下面的代碼中）蟒蛇。其實我沒有收到我電腦的任何報告，說我錯在哪裏。我的電腦沒有顯示任何內容，甚至沒有消息。你能幫我解決這個問題嗎？

在此先感謝。

下面是代碼：

Answer 1

您使用app2 = Calculation (stepOne)，這意味着你將不同的部件在同一網格位置相同的父。在這種情況下的結果是Tkinter根本不顯示任何小部件。

但是即使app2 = Calculation (stepTwo)改變它，你仍然有同樣的問題，這個代碼兩行：

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

您沒有設置任何父母，所以它使用默認Tk的元素，同樣的問題我之前提到過，但這次是根元素。

最後，我強烈建議您只爲每個模塊使用一條導入語句，因爲Tkinter和ttk對某些類使用相同的名稱，如果您使用的是主題小部件，它也會不同。

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