PythonTkinter-填充整个列或行时，按钮消失

Question

我试图建立一个国际象棋游戏在Python使用tkinter的图形。我创建了一个8x8（行和列）的网格，并将瓷砖放在那里（这是一种按钮）。这一切都很好，直到你用棋子填满整行，然后整行消失。我不知道为什么。

当填充整行时，除了一个：https://gyazo.com/865aed481e4a84c5e9e8918695410006

填充整行时：https://gyazo.com/acf48c9790335ba11913b6017d2652c3

如您所见，将显示整行按钮^

这是我的密码：

平铺类的代码（继承tkinter按钮）

class Tile(tk.Button):
    piece = None
    imageLocation = {"bb":"./img/blackBishop.gif",
                     "bk":"./img/blackKing.gif",
                     "bh":"./img/blackHorse.gif",
                     "bp":"./img/blackPawn.gif",
                     "bq":"./img/blackQueen.gif",
                     "br":"./img/blackRook.gif",
                     "wb":"./img/whiteBishop.gif",
                     "wk":"./img/whiteKing.gif",
                     "wh":"./img/whiteHorse.gif",
                     "wp":"./img/whitePawn.gif",
                     "wq":"./img/whiteQueen.gif",
                     "wr":"./img/whiteRook.gif",
    }
    
    def __init__(self, master, *args, **kwargs):
        super(Tile, self).__init__(master, *args, **kwargs)

    def addPiece(self, pieceName):
        self.piece = pieceName
        im = Image.open(self.imageLocation[pieceName])
        photo = ImageTk.PhotoImage(im)
        self.image = photo
        self.config(image=photo)

主类的代码：

def main():
    root = tk.Tk()
    root.title("Chess in Python using tkinter")
    root.geometry("640x640")
    root.resizable(False, False)
    board = Board(root)
    root.mainloop()

if __name__ == "__main__":
    main()

董事会代码：

class Board(tk.Frame):
    move = 0 #
    # Columns and rows
    columns = 8
    rows = 8
    # Size of a square
    square = 75
    
    # A dictionary containing all the tiles
    board = np.empty((8, 8), dtype=Tile)

    def __init__(self, master, *args, **kwargs):
        super(Board, self).__init__(master, *args, **kwargs)

        self.master.rowconfigure((0, 1, 2, 3, 4, 5, 6, 7), weight=1)

        # Create the tiles (as buttons)
        for row in range(self.rows):
            for col in range(self.columns):
                num = row + col
                if num % 2 == 0:

                                         width=self.square, borderwidth=0)
                else:

                self.board[row][col].grid(row=row, column=col)

    def addPiece(self, piece, row, col):
        tile = self.board[row][col]
        tile.addPiece(piece)
    
    def initialPlacement(self):

Answer 1

添加minsize=self。方形到行和列的配置解决了这个问题。
