带有tkinter输入框的动态变量

Question

并感谢您阅读本文。我目前正在将Autohokey脚本转换为完整的Python应用程序。此应用程序将帮助我自动化工作中的服务请求。我目前在理解如何将tkinter输入框设置为动态更新的变量时遇到问题。我相信这个代码有一百万个问题，所以试着对我这么简单！这是我到目前为止：

from tkinter import *
import tkinter as tk
from tkinter.ttk import *

        self.custLabel.grid(row=0, column=0, sticky=W)

        self.custEnt = tk.Entry(self.master, width=10, textvariable=self.CustID)
        self.custEnt.grid(row=0, column=1, sticky=N)

def main(): 
    root = tk.Tk()
    app = SRHelper(root)
    root.mainloop()

if __name__ == '__main__':
    main()

问题在于start_button函数。当按下“开始”按钮时，我希望它将鼠标移动到屏幕上的特定位置，将其中的内容复制到关联变量中，并将其自动更新到主GUI窗口中的不同输入框中。我有一种感觉问题是类和方法/函数之间的继承。我还在学习，所以任何解释都会非常感激。谢谢！
