我正在做的一个项目让我使用tkinter制作游戏板，我还没有使用过tkinter而且我不确定如何完成我想要的东西。
我使用canvas.createRectangle（）创建了一个20x20的正方形板。但我无法改变指定作品的颜色（比如说第8行和第12列的作品。）
我需要一种方法来更改特定的瓷砖填充颜色，并希望此功能能够接收任何坐标并将颜色更改为指定的任何颜色。
如果有比使用createRectangle更好的方法，请告诉我！
我尝试做的是在每个制作的矩形上设置标签，但我无法弄清楚如何使用标签来引用每个矩形。
这是我到目前为止所做的：
#imports
from tkinter import *
#-------------- SET UP THE WINDOW FRAME --------------------------------
class launchScreen(Frame):
#set the initial size of the window please change width and height
#it uses these values to determine the window size
#if you are on a resolution that is not 1920x1080
def __init__(self, master=None, width=0.5, height=0.4):
Frame.__init__(self, master)
#pack the frame to cover the whole window
self.pack(side=TOP, fill=BOTH, expand=YES)
# get screen width and height
ws = self.master.winfo_screenwidth()
hs = self.master.winfo_screenheight()
w = ws*width
h = ws*height
# calculate position x, y
x = (ws/2) - (w/2)
y = (hs/2) - (h/2)
self.master.geometry('%dx%d+%d+%d' % (w, h, x, y))
#Make the screen appear on top of everything.
self.master.overrideredirect(True)
self.lift()
#Once it has launched do everything in Main
if __name__ == '__main__':
root = Tk()
#set the title of the applicaton window
root.title('Blokus')
#--------------------- GAME STARTED ----------------------------------------
def gameStart():
print("Game Started")
#get rid of the launch screen elemenets and show the game board
LaunchScrn.pack_forget()
#this is where the 20x20 grid is made
#set up the view of the game board
def board(view):
w=view.winfo_width()
h=view.winfo_height()
gridWidth = w / 20
gridHeight = h / 20
rowNumber = 0
for row in range(20):
columnNumber = 0
rowNumber = rowNumber + 1
for col in range(20):
columnNumber = columnNumber + 1
rect = view.create_rectangle(col * gridWidth,
row * gridHeight,
(col + 1) * gridWidth,
(row + 1) * gridHeight,
fill = '#ccc')
#Sets row, column
view.itemconfig(rect, tags=(str(rowNumber), str(columnNumber)))
#set up the canvas for the game board grid
viewCanvas = Canvas(root, width=root.winfo_width(), height=root.winfo_height(),bg="#ddd")
viewCanvas.pack(side=TOP, fill=BOTH,padx=1,pady=1)
#when you click on the gameboard this event fires
def clickOnGameBoard(event):
if viewCanvas.find_withtag(CURRENT):
print(viewCanvas.gettags(CURRENT))
print(type(viewCanvas.gettags(CURRENT)))
viewCanvas.itemconfig(CURRENT, fill="yellow")
viewCanvas.update_idletasks()
#bind an event when you click on the game board
viewCanvas.bind("<Button-1>", clickOnGameBoard)
#update the game board after it is done being drawn.
root.update_idletasks()
#show the gameboard in the Canvas
board(viewCanvas)
#when you click the quit button it returns you to the launch screen
def clickToQuit(event):
viewCanvas.destroy()
label.pack_forget()
LaunchScrn.pack(side=TOP, fill=BOTH, expand=YES)
#sets up the button for the quit
quitPath = "images/exit.gif"
quitImg = PhotoImage(file=quitPath)
label = Label(root, image=quitImg)
label.image = quitImg # you need to cache this image or it's garbage collected
#binds clicking this label to the quit event
label.bind("<Button-1>",clickToQuit)
label.pack(side=LEFT)
#------------ GAME ENDED --------------------
def gameEnd():
#quits the game
def quitGame():
print("Game Ended")
LaunchScrn.after(3000,root.destroy())
quitGame()
#---------------------------- LAUNCH SCREEN --------------------------------------------
LaunchScrn = launchScreen(root)
LaunchScrn.config(bg="#eee")
b=Button(LaunchScrn, command=gameStart)
photo2=PhotoImage(file="images/start.gif")
b.config(image=photo2, width="300", height="50")
b.pack(side=RIGHT, fill=X, padx=10, pady=10)
b=Button(LaunchScrn, command=gameEnd)
photo4=PhotoImage(file="images/quit.gif")
b.config(image=photo4, width="300", height="50")
b.pack(side=RIGHT, fill=X, padx=10, pady=10)
root.mainloop()
非常感谢所有能提供帮助的人！

基本上，我定义了一个名为changecolor的函数。我还在第88行调用了该函数的示例。至于访问tile的问题，我在board函数中添加了两行，以便将所有创建的tile存储在字典中。该字典的键是元组(row, column)，从零开始。另外，因为我没有用于按钮的图片，所以我将它们更改为文本，以便我可以运行脚本。随意改变它们。
