[已解决]在函数中怎么访问entry中的内容

lengyue869

我想将以下代码mian函数中的那一坨代码放到win_tk()函数中去该怎么改啊,
如果直接放进去的话run_com()函数中etyText.get()就没办法获取到entry中的内容

1. import tkinter as tk
   
2. from tkinter.filedialog import askopenfilename
   
3. from tkinter.messagebox import *
   
4. 
   
5. 
   
6. def win_tk():
   
7.     pass
   
8. 
   
9. 
   
10. def select_com():
    
11.     etyText.set(askopenfilename())
    
12. 
    
13. 
    
14. def run_com():
    
15.     filePath = etyText.get()
    
16.     showinfo('Tips', filePath)
    
17. 
    
18. 
    
19. if __name__ == '__main__':
    
20.     root = tk.Tk()
    
21.     root.attributes('-alpha', 0.9)
    
22.     root.geometry('700x200+400+200')
    
23.     etyText = tk.StringVar()
    
24.     lb = tk.Label(root, font=('Arial', 10), text=' File Path :')
    
25.     ety = tk.Entry(root, font=('Arial', 10), textvariable=etyText, width=80)
    
26.     btnSelect = tk.Button(root, font=('Arial', 10), text='  Select  ', command=select_com)
    
27.     btnRun = tk.Button(root, font=('Arial', 10), fg='white', bg='gray', text='   Run   ', command=run_com)
    
28. 
    
29.     lb.grid(row=0, column=0)
    
30.     ety.grid(row=0, column=1)
    
31.     btnSelect.grid(row=0, column=2)
    
32.     btnRun.grid(row=1, column=1)
    
33.     tk.mainloop()

较小的改动：改造函数，用函数参数传递所需要处理的对象。若有必要使用全局变量也行。 根据需要返回适当的对象。

较大的改动：用OOP面向对象的方式，改写和实现。
