Question

我编写了一个基于GUI的奥赛罗游戏。重新调整游戏板的大小有点麻烦。这是我到目前为止的代码：

BOXWIDTH=60
BOXHEIGHT=60

class player:
"""Make a user player to play the game via a GUI."""

 def __init__(self,row,column):
    # create the GUI state variables
    self.alive = True
    self.move = None
    self.move_played = False
    # create the GUI windows and handlers
    self.root = tkinter.Tk()
    self.root.wm_title('Othello')
    self.root.protocol("WM_DELETE_WINDOW", self.quit)
    # create a button to get the No move command from the user
    tkinter.Button(self.root, text="No Move", command = self.nomove).pack()
    # create a label for displaying the next player's name
    self.movemesg = tkinter.StringVar()
    tkinter.Label(self.root, textvariable=self.movemesg).pack()
    self.canvas = tkinter.Canvas(self.root, bg="darkgreen",
                                height = BOXHEIGHT*row,
                                width = BOXWIDTH*column)

    self.canvas.bind("<Button-1>", self.click)
    # create a box for highlighting the last move
    self.lastbox = self.canvas.create_rectangle(0, 0, BOXWIDTH*column,
                                                BOXHEIGHT*row,
                                                outline="red")
    # draw the game canvas
    for i in range(1,row):
        # horizontal lines
        self.canvas.create_line(0, i*BOXHEIGHT,
                               BOXWIDTH*column, i*BOXHEIGHT)
    for i in range(1,column):
        # vertical lines
        self.canvas.create_line(i*BOXWIDTH, 0,
                               i*BOXWIDTH, BOXHEIGHT*row)                                
    # the board will store the widgets to be displayed in each square
    self.board = [[None for y in range(row)]
                  for x in range(column)]
    # display the window
    self.canvas.pack()
    self.canvas.focus_set()
    self.root.update()

def draw_board(self, game, last_move):
    """Draw an othello game on the board."""
    ws = str(sum(x.count(1) for x in game.board))
    bs = str(sum(x.count(-1) for x in game.board))
    if game.player == -1:
        self.movemesg.set("Black to play  "+'\nSCORE: White = '+ws+'  Black = ' + bs)
    else:
        self.movemesg.set("White to play  "+'\nSCORE: White = '+ws+'  Black = ' + bs)

    for i in range(game.column):
        for j in range(game.row):
            color = game.get_color((i,j))
            if color == -1:
                board_color = "black"
            elif color == 1:
                board_color = "white"
            else:
                if self.board[i][j] is not None:
                    self.canvas.delete(self.board[i][j])
                    self.board[i][j] = None
                continue

            if self.board[i][j] is None:
                self.board[i][j] = self.canvas.create_oval(
                    i*BOXWIDTH+2, j*BOXHEIGHT+2, (i+1)*BOXWIDTH-2,
                    (j+1)*BOXHEIGHT-2, fill = board_color)
            else:
                self.canvas.itemconfig(self.board[i][j], fill=board_color)

我希望游戏板调整大小，即它必须使绘制板的区域相应地改变大小，重新绘制游戏板以填充可用空间。对此的任何帮助都会很棒。

你的第一个问题是当主窗口增长时画布没有被告知要增长。将您的包语句更改为：

self.canvas.pack(fill="both", expand=True)

接下来，您需要创建一个在画布调整大小时调用的绑定。您可以通过绑定到<Configure>来完成此操作。例如：

self.canvas.bind("<Configure>", self.on_configure)

最后，您需要创建一个除了重绘电路板之外什么都不做的功能。您将从on_configure方法调用此方法。

窗口使用tkinter重新调整大小
