Question

我想按下此网格上的任何方格，我希望它变为黄色。但是我只能使用itemconfig将最近的块创建为黄色。我该怎么办？

from tkinter import *

master = Tk()

canv = Canvas(master, width=200, height=100)
canv.pack()

def select(event):
    print("Coordinates:", event.x, ",",event.y)
    canv.itemconfig(grid,fill="yellow")

y=1
for i in range(1,6):
    for j in range(0,10):
        grid=canv.create_rectangle(1+(20*j),y,20+(20*j),20+y,fill="red")
        canv.tag_bind(grid,'<Button-1>',select)
    y+=20


mainloop()

经过一些实验，我找到了这个解决方案：

from Tkinter import *

master = Tk()

canv = Canvas(master, width=200, height=100)
canv.pack()

def select(event, grid):
    print("Coordinates:", event.x, ",",event.y)
    canv.itemconfig(grid,fill="yellow")

y=1
for i in range(1,6):
    for j in range(0,10):
        grid=canv.create_rectangle(1+(20*j),y,20+(20*j),20+y,fill="red")
        canv.tag_bind(grid, '<Button-1>', lambda event, var=grid: select(event, var))
    y+=20

mainloop()
