我怎样才能得到填充屏幕的框架？

Question

我正在为我的计算机科学项目创建一个测试，我无法获得定制的背景来填充整个屏幕。

这是一个截图在这里输入图像描述

这是我的密码：

from tkinter import*
import customtkinter
import tkinter as tk
from tkinter import ttk
from PIL import ImageTk, Image


class homepage(customtkinter.CTkFrame):
      def __init__(self, master):
          customtkinter.CTkFrame.__init__(self, master)
          self.Frame = customtkinter.CTkFrame(
          master=self,).pack()

          self.Button = customtkinter.CTkButton(self, text="sign up", 
                        command=lambda: master.switch_frame( "pagethree")).pack()
        
          self.Button = customtkinter.CTkButton(self, text="login", 
          command=lambda: master.switch_frame(            "Pageone")).pack()

为什么你不试着把里面的pack()：填充和展开选项？这是找零。

from tkinter import*
import customtkinter
import tkinter as tk
from tkinter import ttk
from PIL import ImageTk, Image


class homepage(customtkinter.CTkFrame):
      def __init__(self, master):
          customtkinter.CTkFrame.__init__(self, master)
          self.Frame = customtkinter.CTkFrame(
          master=self,).pack(fill = 'both', expand = 1)

          self.Button = customtkinter.CTkButton(self, text="sign up", 
                        command=lambda: master.switch_frame( "pagethree")).pack()
        
          self.Button = customtkinter.CTkButton(self, text="login", 
          command=lambda: master.switch_frame(            "Pageone")).pack()
