Tkinterウィジェットは異なるフレームに移動しますか？

Question

私はクイズベースのゲームを作っています。私のウィジェットがどこにでも配置されている理由を理解できないようです。私は自分のStartPageをすべてうまく持っていたが、ページ2のウィジェットを別々のフレームに追加したとき、別のフレームに移動した。あなたのPageTwoクラスで

import tkinter as tk 
from tkinter import * 

TITLE_FONT = ("Helvetica", 18, "bold") 


class foodtechquiz(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 = {} 
     for F in (StartPage, PageOne, PageTwo, PageThree, PageFour, PageFive): 

      page_name = F.__name__ 
      frame = F(parent=container, controller=self) 
      self.frames[page_name] = frame 


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

     self.show_frame("StartPage") 

    def show_frame(self, page_name): 
     #Show a frame for the given page name 
     frame = self.frames[page_name] 
     frame.tkraise() 


class StartPage(tk.Frame): 

    def __init__(self, parent, controller): 

     tk.Frame.__init__(self, parent) 
     self.controller = controller 
     controller.geometry("600x500") 


     label = tk.Label(self, text="Food Technology Quiz", font=TITLE_FONT) 
     label.place(x=160, y=30) 

     name = tk.Label(self, text="By Jett Townsend", font=("comicsansms", 15), bg = "white") 
     name.place(x=220, y=410)

     button3.place(x=430, y=200) 
     button4 = tk.Button(self, text="Safety", 
         command=lambda: controller.show_frame("PageFour")) 
     button4.place(x=175, y=340) 
     button5 = tk.Button(self, text="Food Preperation", 
         command=lambda: controller.show_frame("PageFive")) 
     button5.place(x=350, y=340) 

     banana = PhotoImage(file = "C:/Users/Jett/Downloads/banana1.gif") 
     question_image = Label(self, image = banana) 
     question_image.photo = banana 
     question_image.place(x=70, y=85) 

     hands = PhotoImage(file = "C:/Users/Jett/Downloads/hygiene.gif") 
     question_image = Label(self, image = hands)

     foodprep = PhotoImage(file = "C:/Users/Jett/Downloads/foodprep1.gif") 
     question_image = Label(self, image = foodprep) 
     question_image.photo = foodprep 
     question_image.place(x=338, y=250) 



class PageOne(tk.Frame): 

    def __init__(self, parent, controller): 
     tk.Frame.__init__(self, parent) 
     self.controller = controller 



class PageTwo(tk.Frame): 

    def __init__(self, parent, controller): 


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

     hygieneheading = tk.Label(text="Hygiene", font=("comicsansms", 25), bg = "white") 
     hygieneheading.place(x=235, y=30) 
     question = tk.Label(text="1. Washing water with hot water kills more bacteria than washing with cold.", font=("arial", 10), bg = "white") 
     question.place(x=85, y=100) 
     truebutton = tk.Button(text="True") 
     truebutton.place(x=60, y=300) 
     truebutton.config(height=5, width = 32) 
     falsebutton = tk.Button(text="False") 
     falsebutton.place(x=315, y=300) 
     falsebutton.config(height=5, width = 32) 

class PageThree(tk.Frame): 

    def __init__(self, parent, controller): 
     tk.Frame.__init__(self, parent) 
     self.controller = controller 

class PageFour(tk.Frame): 

    def __init__(self, parent, controller): 
     tk.Frame.__init__(self, parent) 
     self.controller = controller 

class PageFive(tk.Frame): 

    def __init__(self, parent, controller): 
     tk.Frame.__init__(self, parent) 
     self.controller = controller 


if __name__ == "__main__": 
    app = foodtechquiz() 
    app.mainloop() 

Answer 1

、あなたは彼らの親を定義せずにウィジェットを作成します。あなたのウィジェットが右の親に配置されていることを確認するには、この親をウィジェット作成の最初の引数として指定する必要があります。例えば、PageTwoの__init__()方法では、書き込み：

truebutton = tk.Button(self, text="True") 

はtruebutton（そのメソッド内PageTwoインスタンスを表す）selfの子を作ること。
