单击矩形时的python tkinter画布 [英] python tkinter canvas when rectangle clicked

问题描述

当我点击 tk 画布上的一个矩形时，我一直试图让一个函数运行.

I've been trying to make a function run when I click a rectangle on a tk canvas.

代码如下:

from tkinter import *

window = Tk()

c = Canvas(window, width=300, height=300)

def clear():
    canvas.delete(ALL)

playbutton = c.create_rectangle(75, 25, 225, 75, fill="red")
playtext = c.create_text(150, 50, text="Play", font=("Papyrus", 26), fill='blue')

c.pack()

window.mainloop()

有人知道我应该做什么吗?

does anyone know what I should do?

推荐答案

您可以在要绑定事件的项目上添加标签.
这里你想要的事件是 ，也就是鼠标左键.
要将其应用于您的示例，您可以这样做:

You can add tags on the items you want to bind events to.
The event you want here is <Button-1>, which is left mousebutton.
To apply this to your example, you can do like this:

from tkinter import Tk, Canvas

window = Tk()

c = Canvas(window, width=300, height=300)

def clear():
    canvas.delete(ALL)

def clicked(*args):
    print("You clicked play!")

playbutton = c.create_rectangle(75, 25, 225, 75, fill="red",tags="playbutton")
playtext = c.create_text(150, 50, text="Play", font=("Papyrus", 26), fill='blue',tags="playbutton")

c.tag_bind("playbutton","<Button-1>",clicked)

c.pack()

window.mainloop()
