在python中单击时单击tkinter矩形时更改颜色 [英] Changing the colour on click of a tkinter rectangle on click in python

问题描述

所以我有这个代码绘制一个简单的矩形:

So I have this code which draws a simple rectangle:

from tkinter import *

root = Tk()
canvas = Canvas(root, width = 500, height = 500)
canvas.pack()

canvas.create_rectangle(100, 100, 400, 400, fill='black')


mainloop()

现在我到处寻找，似乎根本找不到改变填充颜色的方法，理想情况下，我希望能够通过点击来做到这一点.

Now I've been looking everywhere, and can't seem to find a way to change the fill colour at all, and ideally I'd like to be able to do this on click.

我实际上将使用它来更改由我编写的函数生成的六边形的颜色

I'm actually going to be using this to change the colour of hexagons generated by a function I wrote that works fine using

create_polygon()

但我想它与矩形的工作方式相同.

but I imagine it'll work identically with a rectangle.

我意识到可能需要完全重构代码.

I realise the code may need to be completely restructured.

推荐答案

命名然后通过itemconfig引用，像这样:

Name it and then refer to it through itemconfig, like this:

myrectangle = canvas.create_rectangle(100, 100, 400, 400, fill='black')
canvas.itemconfig(myrectangle, fill='red')
