Python tkinter 销毁窗口

Question

我是Python的初学者，我正在尝试为自己做一些事情，但无法弄清楚如何在单击按钮并打开新窗口后销毁第一个窗口，并且它将保留在第一个窗口中为第二个窗口输入的变量对吗？

from tkinter import *
import tkinter as tk
import sys
def showdata():
    email1 = email.get()
    password2 = password1.get()
    print(email1 +" "+ password2)
    exec(open("scratch.py").read())


window = tk.Tk()
window.title("CANmail")
window.geometry("300x150")
em = Label(window, text="E-mail").place(relx=0.2,rely=0.2)

pd = Label(window, text="Password").place(relx=0.2,rely=0.4)

email = Entry(window)
password1 = Entry(window)

email.grid(row=0, column=1)
email.place(relx=0.5,rely=0.2)
password1.grid(row=1, column=1)
password1.place(relx=0.5,rely=0.4)

btn = Button(window, text="Log In", command=showdata)
btn.grid(row=2, column=1)
btn.place(relx=0.5,rely=0.7,anchor=CENTER)

window.mainloop()

Answer 1

当点击按钮并调用显示数据函数时调用函数:

def quit(window):
    window.destroy()

它认为它会对你有帮助。 这是另一个例子:

import tkinter


class App():
   def __init__(self):
       self.root = Tkinter.Tk()
       button = Tkinter.Button(self.root, text = 'root quit', command=self.quit)
       button.pack()
       self.root.mainloop()

   def quit(self):
       self.root.destroy()

app = App()
