Tkinter将功能绑定到鼠标左键不起作用

Question

for some reason binding a function that finds the x and y coordinates to a mouse click event just isn't working, when I left click absolutely nothing happens, but if I call out the function in the actual code it runs fine. I tried other solutions posted on this site but they did not seem to help. using python 3.4 Here's my exact code:

#Import TKINTER toolset:
from tkinter import *

#Starting variables:
#Defining mouse x and y coordinates
global mouse_x
global mouse_y
mouse_x = 0
mouse_y = 0

#Main window:
window = Tk()

#Workspace and Canvas:
wrkspace =  Frame(window, bg="red",width=640,height=480)
canvas = Canvas(wrkspace,bg="white",width=640,height=480)

#Keyframe editor: (DO LATER)

#Displays mouse x and y on workspace:
def find_mouse_xy():
    mouse_x = wrkspace.winfo_pointerx()
    mouse_y = wrkspace.winfo_pointery()
    print ("x: " + str(mouse_x))
    print ("y: " + str(mouse_y))

wrkspace.bind("<Button-1>",find_mouse_xy)

wrkspace.pack()
canvas.pack()

#Runs window:
window.mainloop()

Answer 1

Your Canvas is catching the mouse event, but you have it bound to your Frame .

Try binding it to the canvas instead.

canvas.bind("<Button-1>",find_mouse_xy)

Also, you will need an argument for your find_mouse_xy() function for the event that will be passed to it.

def find_mouse_xy(event):
