Tkinter，草稿板

Question

我想创建一个草稿游戏板。 起初，当我在“板”画布上直接绘制正方形和棋子时，一切正常。由于我之后必须操纵这些棋子，我希望通过创建每个方块和棋子作为对象来更明确。 所以我试图创建一个包含黑色或白色方块的棋盘，其中包含圆圈（棋子）。然后一切都搞砸了。我不知道为什么。即便如此，它看起来也很合乎逻辑（对我而言）。

我认为这与使用pack方法有关。

以下是代码：

from tkinter import *



class Parent(Tk):

    def getRoot(self):
        return(self.body)

    def setTitle(self,title):
        self.title(title)

    def run(self):
        self.mainloop()

class Drawing:
    def __init__(self,root,width,height):
        self.zone=Canvas(root, width=width, height=height)

    def put(self,root,row,col):
        self.zone.grid(root,row=row,column=col)

    def getDrawing(self):
        return(self.zone)

    def rectangle(self,coordX1,coordY1,coordX2,coordY2,color):
        self.zone.create_rectangle(coordX1,coordY1,coordX2,coordY2,fill=color, outline="black")

    def circle(self,coordX1,coordY1,coordX2,coordY2,color):
        self.zone.create_oval(coordX1,coordY1,coordX2,coordY2,fill=color,outline="black")

if __name__=="__main__":
    root=Parent()
    root.setTitle("Draughts")
    board=Drawing(root,400,400)
    size=40
    logicBoard=[[0, -1, 0, -1, 0, -1, 0, -1, 0, -1], 
                [-1, 0, -1, 0, -1, 0, -1, 0, -1, 0],
                [0, -1, 0, -1, 0, -1, 0, -1, 0, -1], 
                [-1, 0, -1, 0, -1, 0, -1, 0, -1, 0], 
                [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], 
                [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], 
                [0, 1, 0, 1, 0, 1, 0, 1, 0, 1], 
                [1, 0, 1, 0, 1, 0, 1, 0, 1, 0], 
                [0, 1, 0, 1, 0, 1, 0, 1, 0, 1], 
                [1, 0, 1, 0, 1, 0, 1, 0, 1, 0]]
    DIMENSION=10
    for i in range(DIMENSION):
        for j in range(DIMENSION):
            coordX1 = (i * size)
            coordY1 = (j * size)
            coordX2 = coordX1 + size
            coordY2 = coordY1 + size
            if(not(i%2==j%2)):#if the square is black (on the board)
                color="black"
            else:
                color="white"
            case=Drawing(board.getDrawing(),40,40)
            case.rectangle(coordX1,coordY1,coordX2,coordY2,color)
            case.getDrawing().pack()
            if(logicBoard[i][j]>0):
                pawnColor="white"
            elif(logicBoard[i][j]<0):
                pawnColor="black"
            if (not(i%2==j%2)):
                pawn=Drawing(case.getDrawing(),40,40)
                pawn.circle(0,0,30,30,pawnColor)
                pawn.getDrawing().pack()

    board.getDrawing().pack()
    root.run()

谢谢！

这就是我得到的：

问题是你在每次迭代中创建一个新的Canvas并在其上调用pack()，而不是使用你在开始时创建的那个。最后，您使用课程Drawing创建新的Drawings。我建议你只使用一个类代表所有的棋盘，用方法绘制正方形和圆圈。

我已经改变了椭圆的颜色以获得更好的对比度：

from tkinter import Tk, Canvas
from itertools import product

class Board(Tk):
    def __init__(self, width, height, cellsize):
        Tk.__init__(self)
        self.cellsize = cellsize
        self.canvas = Canvas(self, width=width, height=height)
        self.canvas.bind("<Button-1>", self.onclick)
        self.canvas.pack()
    def draw_rectangle(self, x1, y1, x2, y2, color):
        self.canvas.create_rectangle(x1, y1, x2, y2, fill=color, outline="black")
    def draw_circle(self, x1, y1, x2, y2, color):
        self.canvas.create_oval(x1, y1, x2, y2, fill=color, outline="black")
    def onclick(self, event):
        i = int(event.x / self.cellsize)
        j = int(event.y / self.cellsize)
        print "You clicked on cell (%s, %s)" % (i, j)

if __name__=="__main__":
    size = 40
    board = Board(400, 400, size)
    board.title("Draughts")
    logicBoard = [[0, -1, 0, -1, 0, -1, 0, -1, 0, -1], 
                  [-1, 0, -1, 0, -1, 0, -1, 0, -1, 0],
                  [0, -1, 0, -1, 0, -1, 0, -1, 0, -1], 
                  [-1, 0, -1, 0, -1, 0, -1, 0, -1, 0], 
                  [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], 
                  [0, 0, 0, 0, 0, 0, 0, 0, 0, 0], 
                  [0, 1, 0, 1, 0, 1, 0, 1, 0, 1], 
                  [1, 0, 1, 0, 1, 0, 1, 0, 1, 0], 
                  [0, 1, 0, 1, 0, 1, 0, 1, 0, 1], 
                  [1, 0, 1, 0, 1, 0, 1, 0, 1, 0]]
    for (i, j) in product(range(10), range(10)):
        coordX1 = (i * size)
        coordY1 = (j * size)
        coordX2 = coordX1 + size
        coordY2 = coordY1 + size
        color = "white" if i%2 == j%2 else "black"
        board.draw_rectangle(coordX1, coordY1, coordX2, coordY2, color)
        cell = logicBoard[i][j]
        if cell != 0:
            pawnColor = "red" if cell > 0 else "blue"
            board.draw_circle(coordX1, coordY1, coordX2, coordY2, pawnColor)
    board.mainloop()

修改

如果要跟踪点击次数，将处理函数绑定到画布并计算点数会更清晰，更简单，而不是使用自己的事件处理程序创建大量画布。
