python tkinter 封装成类函数
要把 tkinter 界面写成类函数放在一个模块里(easy_excel)供主程序process_compare调用。没有写过类，类下面的各个def
函数要如何串起来呢？
画布上一个processbar 展示文件读取进度，两个button start 和quit , quit,start button不显示. start button 的command
写在了主程序里面，ob.update_progress(files, command_bt)报错。
欢迎指教。
class WindowManager():#https://www.5axxw.com/questions/content/fii6kx # initializing the root
def __init__(self):
self.root = tkinter.Tk()
self.root.title('Step 1 of 4')

self.progress_bar.pack(padx=10,pady=20)

ob = WindowManager()
ob.update_progress(files, command_bt)# 调用对象的函数
下面是主程序对progressbar 和start button 的调用
