成功登錄tkinter后如何銷毀Class window？

Question

我當前的代碼位於底部

成功登錄后我試圖關閉Window1並打開Window2

目前，我僅出於測試目的輸入用戶名。

如果one是用戶名條目，我當前的if語句會打開新的 window。 但是顯示了兩個 windows。

我需要擺脫 Window 1 並在成功登錄后只顯示 Window 2 。

我做了一些研究並找到了這個答案，但我認為這不適用於我當前的代碼。

我也嘗試了以下方法，但出現錯誤：

def login_system(self):
    u = self.UsernameEntry.get()
    if u == "one":
        self.newWindow = Toplevel(self.master)
        self.app = Window2(self.newWindow)
        Window1().destory()

錯誤：

TypeError: __init__() missing 1 required positional argument: 'master'

我怎樣才能做到這一點？

from tkinter import *
from tkinter import DISABLED, messagebox
import tkinter.ttk as ttk
import os
import glob
from PIL import Image, ImageTk, ImageGrab
from pathlib import Path
import pyautogui
import time

def main():
    root = Tk()
    app = Window1(root)
    root.mainloop()

class Window1:
    def __init__(self,master):
        self.master = master
        self.master.title("User Log In")
        self.master.geometry('1000x750')
        self.frame = Frame(self.master)
        self.frame.pack(fill="both", expand=True)


        self.UsernameEntry = Entry(self.frame)
        self.UsernameEntry.grid(row = 2, column = 0)


        self.btnLogin = Button(self.frame, text = 'login', width = 17, command = self.login_system)
        self.btnLogin.grid(row = 3, column = 0)

    def login_system(self):
        u = self.UsernameEntry.get()
        if u == "one":
            self.newWindow = Toplevel(self.master)
            self.app = Window2(self.newWindow)

        else:
            self.UsernameEntry.delete(0,"end")


class Window2:
    def __init__(self,master):
        notebook = ttk.Notebook(master)

        notebook.pack(expand = 1, fill = "both")
        #Frames
        main = ttk.Frame(notebook)
        manual = ttk.Frame(notebook)
        notebook.add(main, text='Main-Screen')
        notebook.add(manual, text='Manual')



if __name__ == '__main__':
    main()

您正在使用許多不需要的庫。 無論如何，您只需要一行代碼就可以在 if 語句self.master.withdraw()內部工作

--EDIT-- 因為你要求它，我添加了一個 function 來關閉 cmd

完整代碼

from tkinter import *
...

def main():
    root = Tk()
    app = Window1(root)
    root.mainloop()

class Window1:
    def __init__(self,master):
        self.master = master
        ....

    self.btnLogin = Button(self.frame, text = 'login', width = 17, command = self.login_system)
    self.btnLogin.grid(row = 3, column = 0)

    def on_closing(self): #Add this event handler
        self.master.destroy()

    def login_system(self):
        u = self.UsernameEntry.get()
        if u == "one":
            self.master.withdraw() #Do NOT call destroy as you need the root to be 
                                   #active for Toplevel
            self.newWindow = Toplevel(self.master)
            self.newWindow.protocol("WM_DELETE_WINDOW", self.on_closing) #And add this

            self.app = Window2(self.newWindow)

        else:
            self.UsernameEntry.delete(0,"end")


class Window2:
    ....



if __name__ == '__main__':
    main()
