如何在按下tkinter中的按钮时获取鼠标位置？

Question

I'm trying to get the mouse position while pressing a button, but instead of getting the position of the mouse on Tkinter root, it gives me the position of the mouse on the button. For example, if the button is placed on 200, 200, and I press the top left of the button, it prints 0, 0 instead of 200, 200.

import Tkinter as tk

def leftclick(event):
    print("left")
    x, y = event.x, event.y
    print('{}, {}'.format(x, y))

root = tk.Tk()
add_user = tk.Button(root, height=63, width=195 ,text="sign up a user")
add_user.place(x= 20, y = 30)
root.bind("<Button-1>", leftclick)
root.mainloop()

You can call the winfo_pointerx and winfo_pointery methods of a widget to get each individual coordinate, or you can call winfo_pointerxy to get them both:

def leftclick(event):
    x, y = event.widget.winfo_pointerxy()
    print('{}, {}'.format(x, y))
