问如何在python中创建一个没有最小化、最大化和关闭按钮的窗口？

EN

# basic example
import tkinter as tk

root = tk.Tk()
root.transient()  # does nothing - min/max buttons are still shown
win = tk.Toplevel(root)
win.transient(root)  # works as intended - only close button is shown
root.mainloop()

# classy OOP example
import tkinter as tk


class App(tk.Tk):
    def __init__(self):
        super().__init__()
        self.transient()  # does nothing - min/max buttons are still shown
        self.win = tk.Toplevel(self)
        self.win.transient(self)  # works as intended - only close button is shown
   

if __name__ == '__main__':
    app = App()
    app.mainloop()
