Question

我需要帮助。我需要在genkeymenu函数中将图像背景显示到我新创建的帧中。但问题是，一旦创建了框架，图像背景似乎只会在第一个创建的框架中发生变化。我试图寻找解决方案，但没有任何作用。我可以问一下这是什么问题吗？

您指定要在顶层窗口中显示的所有窗口小部件，但不会为后台执行此操作。 background_label = Label(generatemenu, image=bg1)

import Tkinter as tk
from Tkinter import *
PIL import Image, ImageTk



def genkeymenu():
    generatemenu = tk.Toplevel(mainmenu)

    bg1 = ImageTk.PhotoImage(file="key2.jpg")
    background_label = Label(generatemenu, image=bg1)# specify the window you it to appear.
    background_label.place(x=0, y=0)
    background_label.image = bg1

    keynamelabel = Label(generatemenu, text="Enter your key name")

    keynameEntry = Entry(generatemenu)

    keynameButton = Button(generatemenu, text="Enter")


    check1024= Checkbutton(generatemenu, text="1024 bit")
    check2048= Checkbutton(generatemenu, text="2048 bit")
    check4096= Checkbutton(generatemenu, text="4096 bit")

    tk.background_label.grid(row=0)

    keynamelabel.grid(row=0)
    keynameEntry.grid(row=1)
    keynameButton.grid(row=2)

    check1024.grid(row=3, column=0)
    check2048.grid(row=3, column=1)
    check4096.grid(row=3, column=2)

    generatemenu.title("Generate Key")
    generatemenu.mainloop()


mainmenu = tk.Tk()

bg = ImageTk.PhotoImage(file="key.jpg")
background_label = Label(image=bg)
background_label.place(x=0, y=0)

genkeybutton = Button(mainmenu, text= "Generate Key Pair", fg="black", 
command=genkeymenu)
encryptbutton = Button(mainmenu, text= "Encrypt your message", fg="black")
decryptbutton = Button(mainmenu, text= "Decrypt your message", fg="black")

background_label.grid(row=0)

genkeybutton.grid(row=0, column=0, sticky = N, rowspan=2)

encryptbutton.grid(row=0, column=0)

decryptbutton.grid(row=0, column=0, sticky=S)

mainmenu.title("RSA ENCRYPTION")
mainmenu.mainloop()

如何将背景图像放在第二帧？
