我如何使用按钮创建一个棋盘，其中每个方块都有一个定义的 x 和 y 值？

Question

如何在此 canvas 之上为每个方块创建按钮，每个方块都有自己独特的值（从左下角的 (1,1) 开始）？我正在尝试制作一个下棋程序。我需要 canvas 上的这些方块，每个方块都有一个具有定义坐标的按钮。这也可以更改为仅 64 个按钮，但这是针对一个程序，如果方块可以移动到该选项，则方块将突出显示。

import tkinter as tk


class Layout(tk.Tk):
    colours = ["#563a12", "#9f9362"]#square colours dark then light

    def __init__(self, n=8):
        super().__init__()
        self.n = n
        self.leftframe = tk.Frame(self)
        self.leftframe.grid(row=0, column=0, rowspan=10, padx=100)
        self.middleframe = tk.Frame(self)
        self.middleframe.grid(row=0, column=8, rowspan=8)
        self.canvas = tk.Canvas(self, width=1200, height=768, )
        self.canvas.grid(row=0, column=1, columnspan=8, rowspan=8)
        self.board = [[None for row in range(n)] for col in range(n)]

        self.colourindex = 0



    def changecolours(self):
        self.colourindex = (self.colourindex + 1) % 2

    def drawboard(self):

        for col in range(self.n):
            self.changecolours()
            for row in range(self.n):
                x1 = col * 90
                y1 = (7-row) * 90
                x2 = x1 + 90
                y2 = y1 + 90
                colour = self.colours[self.colourindex] 
                self.board[row][col] = self.canvas.create_rectangle(x1, y1, x2, y2, fill=colour)

                self.changecolours()
board = Layout()
board.drawboard()
board.mainloop()

看来您只需要棋盘图块的坐标。如果是这样，您可以使用唯一名称标记每个图块，然后使用 canvas.tag_bind:

绑定它们

import tkinter as tk

class Layout(tk.Tk):
    colours = ["#563a12", "#9f9362"]#square colours dark then light

    def __init__(self, n=8):
        super().__init__()
        self.n = n
        self.leftframe = tk.Frame(self)
        self.leftframe.grid(row=0, column=0, rowspan=10, padx=100)
        self.middleframe = tk.Frame(self)
        self.middleframe.grid(row=0, column=8, rowspan=8)
        self.canvas = tk.Canvas(self, width=1200, height=768, )
        self.canvas.grid(row=0, column=1, columnspan=8, rowspan=8)
        self.board = [[None for row in range(n)] for col in range(n)]

    def drawboard(self):
        from itertools import cycle
        for col in range(self.n):
            color = cycle(self.colours[::-1] if not col % 2 else self.colours)
            for row in range(self.n):
                x1 = col * 90
                y1 = (7-row) * 90
                x2 = x1 + 90
                y2 = y1 + 90
                self.board[row][col] = self.canvas.create_rectangle(x1, y1, x2, y2, fill=next(color), tags=f"tile{col+1}{row+1}")
                self.canvas.tag_bind(f"tile{col+1}{row+1}","<Button-1>", lambda e, i=col+1, j=row+1: self.get_location(e,i,j))

    def get_location(self, event, i, j):
        print (i, j)

board = Layout()
board.drawboard()
board.mainloop()
