Tkinter:刷新窗口(基于类)，同时关闭另一个窗口

import tkinter as tk

class MainWindow(tk.Tk):
    def __init__(self):
        super().__init__()
        self.title("Main Window")
        self.button = tk.Button(self, text="Open Sub Window", command=self.open_sub_window)
        self.button.pack()

    def open_sub_window(self):
        sub_window = SubWindow(self)
        self.update()  # 刷新主窗口

class SubWindow(tk.Toplevel):
    def __init__(self, master):
        super().__init__(master)
        self.title("Sub Window")
        self.label = tk.Label(self, text="Sub Window")
        self.label.pack()
        self.protocol("WM_DELETE_WINDOW", self.close_windows)  # 关闭窗口时调用close_windows方法

    def close_windows(self):
        self.master.destroy()  # 关闭主窗口

if __name__ == "__main__":
    main_window = MainWindow()
    main_window.mainloop()
