将对象放置在使用绑定python单击的画布中

Question

我想让一个对象出现在用户单击的 tkinter 窗口中。 我有这个代码：

from tkinter import *

class Storage:

    def __init__(self):
        x = None
        circle = None
        w=None

class Game:

    def Start():
        #make object appear where clicked

root = Tk()

w = Canvas(root, width=200, height=100)
w.pack()

w.bind("<Button-1>", Start)


start = Button(text="Start!", command=Game.Start)
start.pack()

root.mainloop()

任何帮助将不胜感激。

首先你应该将画布对象放在框架上，然后将画布绑定到所需的事件

from tkinter import *

class Storage:

    def __init__(self):
        x = None
        circle = None
        w=None

class Game:

    def Start(event):
        print("clicked at", event.x, event.y)
        x = event.x
        y = event.y
        w.create_rectangle(x, y, 100, 100, fill="blue")

root = Tk()




frame = Frame(root, width=200, height=200)

frame.pack()
w = Canvas(frame, width=200, height=100)
w.pack()
w.bind("<Button-1>", Game.Start)

root.mainloop()
