如何让一个tkinter框显示在另一个tkinter窗口中？

Question

我想做一个密码存储和哈希系统的图形用户界面，但我遇到了一个障碍。我有两个按钮，一个用来登录，另一个用来创建账户。当点击登录按钮时，一个新的tkinter窗口打开，并显示登录页面。然而，登录按钮应该显示在第二页，但它没有，我不知道为什么。这里是整个系统的代码。

import tkinter
from tkinter import*

username = ("Tom")
password = ("test") 
usernameguess1 = ("")
passwordguess1 = ("")


def trylogin():
   print ("Trying to login...")
   if usernameguess.get() == username:
       print ("Complete sucsessfull!")
       messagebox.showinfo("Sucess ", "Successfully logged in.")
   else:
       print ("Error: (Incorrect value entered)")
       messagebox.showinfo("Error", "Sorry, but your username or password is incorrect. Try again")

def loginpage():
    #Gui Formatting
    window = tkinter.Tk()
    window.resizable(width=FALSE, height=FALSE)
    window.title("HasherTest_V0.1 Login")
    window.geometry("300x150")

    #Username and password boxes
    usernametext = tkinter.Label(window, text="Username:")
    usernameguess = tkinter.Entry(window)
    passwordtext = tkinter.Label(window, text="Password:")
    passwordguess = tkinter.Entry(window, show="*")

    usernameguess1 = usernameguess

    #login button

    attemptlogin = tkinter.Button(text="Login", command=trylogin)

    usernametext.pack()
    usernameguess.pack()
    passwordtext.pack()
    passwordguess.pack()
    attemptlogin.pack()
    window.mainloop()


#Gui Formatting (again)
window = tkinter.Tk() 
window.resizable(width=FALSE, height=FALSE)
window.title("HasherTest_V0.1")
window.geometry("300x150")

loginbutton = tkinter.Button(text="Login", command=loginpage)
loginbutton.pack()

这里是第二个窗口的代码. 由于某些原因，我必须把tkinter消息框也导入，否则我的IDLE就会出错。

import tkinter
from tkinter import *
from tkinter import messagebox

username = ("Tom")
password = ("test") 
usernameguess1 = ("")
passwordguess1 = ("")


def trylogin():
   print ("Trying to login...")
   if usernameguess.get() == username:
       print ("Complete sucsessfull!")
       messagebox.showinfo("Sucess ", "Successfully logged in.")
   else:
       print ("Error: (Incorrect value entered)")
       messagebox.showinfo("Error", "Sorry, but your username or password is incorrect. Try again")

#Gui Formatting
window = tkinter.Tk() 
window.resizable(width=FALSE, height=FALSE)
window.title("HasherTest_V0.1 Login")
window.geometry("300x150")


#Username and password boxes
usernametext = tkinter.Label(window, text="Username:")
usernameguess = tkinter.Entry(window)
passwordtext = tkinter.Label(window, text="Password:")
passwordguess = tkinter.Entry(window, show="*")

usernameguess1 = usernameguess

#login button
attemptlogin = tkinter.Button(text="Login", command=trylogin)

usernametext.pack()
usernameguess.pack()
passwordtext.pack()
passwordguess.pack()
attemptlogin.pack()
window.mainloop()

谢谢你的帮助!

在这里，我完全重做了你的代码。我完全重写了你的代码，它可以工作了（据我所知）。

我完全删除了 textvariable 和 StringVar(). 它们是不需要的。你的代码没有工作的原因是你检查文件名 "string"，但你需要添加".txt"，以获得一个完美的平等。

的代码。

import tkinter
from tkinter import*

from tkinter import messagebox

username = ("Tom")
password = ("test") 
usernameguess1 = ("")
passwordguess1 = ("")



def loginpage():
    #Gui Formatting
    root = tkinter.Toplevel()
    #root.resizable(width=FALSE, height=FALSE)
    root.title("HasherTest_V0.1 Login")
    root.geometry("300x150")

    #Username and password boxes
    usernametext = tkinter.Label(root, text="Username:")
    usernameguess = tkinter.Entry(root)
    passwordtext = tkinter.Label(root, text="Password:")
    passwordguess = tkinter.Entry(root, show="*")

    usernameguess1 = usernameguess
    def trylogin():
        print ("Trying to login...")
        if usernameguess.get() == username:
           print ("Complete sucsessfull!")
           messagebox.showinfo("Sucess ", "Successfully logged in.")
        else:
            print ("Error: (Incorrect value entered)")
            messagebox.showinfo("Error", "Sorry, but your username or password is incorrect. Try again")
        #login button

    attemptlogin = tkinter.Button(root, text="Login", command=trylogin)

    usernametext.pack()
    usernameguess.pack()
    passwordtext.pack()
    passwordguess.pack()
    attemptlogin.pack()
    window.mainloop()


#Gui Formatting (again)
window = tkinter.Tk()
window.resizable(width=FALSE, height=FALSE)
window.title("HasherTest_V0.1")
window.geometry("300x150")

loginbutton = tkinter.Button(window, text="Login", command=loginpage)
loginbutton.pack()

window.mainloop()

我还冒昧地像@stovfl所说的那样，添加了".txt"。Toplevel() 实例，而不是使用 Tk() 多次。

希望对大家有所帮助!
