Tkinter画布更新

Question

我正在构建一个包含一个计数器和一个图像的脚本。两者都在单个窗口的不同画布上。我试图在计时器停止后更新画布图像。以下是我的代码。我没有弄到这个

的错误

from Tkinter import *
import Tkinter as tk
import stopwatch
import stone_image


class App():

    def __init__(self, root):
        self.root = root
        self.root.configure(background="yellow")

        global stoneImagePanel

        stopwatchPanel = tk.Canvas(self.root, background="yellow")
        stoneImagePanel = tk.Canvas(self.root, background="yellow")

        stopwatchPanel.grid(row=0, column=0, columnspan=4, sticky="e")
        stoneImagePanel.grid(row=1, column=0, rowspan=2, columnspan=4, sticky="news")


        self.stoneImage_canvas(stoneImagePanel)
        self.stopWatch_canvas(stopwatchPanel)


    def stopWatch_canvas(self, parent):
        stopwatch.timerStart(parent, 500)
        stoneImagePanel.after(500, self.update(stoneImagePanel))

    def stoneImage_canvas (self, parent):
        displayImage = stone_image.DisplayImage(parent)
        displayImage.stoneImg('images/stone.jpg')

    def update(self, parent):
        displayImage = stone_image.DisplayImage(parent)
        displayImage.stoneImg('images/UP.png')



if __name__ == "__main__":

    root = Tk()
    app = App(root)

    root.mainloop()

秒表工作不顺畅，图像也没有更新。请帮忙。
