from tkinter import *

class GameBoard(Frame):
  def __init__(self):
    Frame.__init__(self)
    self.master.title("test")
    self.grid()
    #button frame
    self.__buttonPane = Frame(self)
    self.__buttonPane.grid()
    #buttons
    self.__buttonA1 = Button(self.__buttonPane,text = "A1",command = self._close)
    self.__buttonA1.grid()

  def _close(self):
    GameBoard().destroy()


def main():
  GameBoard().mainloop()

main()

我如何让我的功能接近工作？
