单击矩形时的python tkinter画布

Question

当我单击 tk 画布上的矩形时，我一直试图让函数运行。

这是代码：

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()

有谁知道我应该做什么？

您可以在要绑定事件的项目上添加标签。
您在这里想要的事件<Button-1>是鼠标左键。
要将其应用于您的示例，您可以这样做：

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()
