新手问题在这里。secondWindow除了thirdWindow单击红色X时，我还希望销毁它thirdWindow，就像单击thirdButton时一样thirdWindow。firstWindow应该活着。
下面是一些示例代码：
import tkinter
from tkinter import ttk
def secondWindow():
secondWindow = tkinter.Toplevel(firstWindow)
secondFrame = ttk.Frame(secondWindow)
secondFrame.pack()
secondButton = ttk.Button(secondFrame, text="proceed to 3rd window",\
command=lambda: thirdWindow(secondWindow))
secondButton.pack()
def thirdWindow(parent):
thirdWindow = tkinter.Toplevel(parent)
thirdFrame = ttk.Frame(thirdWindow)
thirdFrame.pack()
thirdButton = ttk.Button(thirdFrame, text="close 2nd and 3rd windows",\
command=lambda: destroy(thirdWindow, parent))
thirdButton.pack()
def destroy(self, parent):
self.destroy()
parent.destroy()
firstWindow = tkinter.Tk()
firstFrame = ttk.Frame(firstWindow)
firstFrame.pack()
firstButton = ttk.Button(firstFrame, text="proceed to 2nd window",\
command=secondWindow)
firstButton.pack()
firstWindow.mainloop()
在此先感谢您提供的任何帮助！
添加thirdWindow.protocol("WM_DELETE_WINDOW", lambda: destroy(thirdWindow, parent))到thirdWindow()功能似乎已经完成了。
