单击矩形时的python tkinter Canvas

Question

当我单击 tk Canvas 上的矩形时，我一直在尝试运行一个函数。

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()

有谁知道我应该怎么做？

Answer 1

您可以在要将事件绑定(bind)到的项目上添加标签。
您想要的事件是<Button-1> ，即鼠标左键。
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()
