我已经使用tkinter用Python创建了一个程序。我为两个窗口创建了两个独立的类。我正在通过单击一个窗口的按钮来打开另一个窗口。我希望当新的窗口打开时,另一个窗口应该关闭。我的代码是
from tkinter import Tk, Toplevel
from tkinter import *
def main():
main_window = Tk()
app = first(main_window)
main_window.mainloop()
class first:
def __init__(self, root):
self.root = root
self.root.title('First window')
self.root.geometry('1350x700+0+0')
frame1 = Frame(self.root, bg='black')
frame1.place(x=400, y=50, width=400, height=600)
btn_1 = Button(frame1, command=self.second_window, text='open second window', font=("Times New Roman", 15, 'bold'), bd=3,
relief=RIDGE,
cursor='hand2', bg='red', fg='white', activeforeground='white', activebackground='red')
btn_1.place(x=100, y=350, width=220, height=35)
def second_window(self):
self.new_window = Toplevel(self.root)
self.app = second(self.new_window)
class second:
def __init__(self, root):
self.root = root
self.root.title('Second Window')
self.root.geometry("1350x700+0+0")
self.root.config(bg='white')
frame1 = Frame(self.root, bg='black')
frame1.place(x=400, y=50, width=400, height=600)
btn_1 = Button(frame1, command=self.first_window, text='open first window',
font=("Times New Roman", 15, 'bold'), bd=3,
relief=RIDGE,
cursor='hand2', bg='red', fg='white', activeforeground='white', activebackground='red')
btn_1.place(x=100, y=350, width=220, height=35)
def first_window(self):
self.new_window = Toplevel(self.root)
self.app = first(self.new_window)
if __name__ == '__main__':
main()
我知道这个问题很常见,但我在这里找不到一个适用于我的代码的解决方案。

您可以使用Tk类销毁前一个窗口并启动一个新窗口
from tkinter import *
from tkinter.ttk import Button
root = Tk()
root.title("title")
root.geometry("800x500")
def window2():
root.destroy()
window2_main = Tk()
Label(window2_main, text="Bye Bye").pack()
window2_main.mainloop()
a = Button(text="Click This", command=window2)
a.pack()
root.mainloop()
