tkinter的Label组件使用问题

wmxs

1. from tkinter import *
   
2. 
   
3. def check(num):
   
4.     return num.isdigit()
   
5. 
   
6. root = Tk()
   
7. 
   
8. frame1 = Frame(root)
   
9. frame1.pack(padx = 10, pady = 10)
   
10. frame2 = Frame(root)
    
11. frame2.pack(padx = 10, pady = 10)
    
12. 
    
13. v1 = StringVar()
    
14. v2 = StringVar()
    
15. 
    
16. check_num = root.register(check)
    
17. e1 = Entry(frame1, textvariable = v1, validate = 'key', validatecommand = (check_num, '%P'))
    
18. e1.grid(row = 0, column = 0)
    
19. e2 = Entry(frame1, textvariable = v2)
    
20. e2.grid(row = 0, column = 2)
    
21. e3 = Entry(frame1, state = "readonly")
    
22. e3.grid(row = 0, column = 4)
    
23. 
    
24. Label(root, text = '+').grid(row = 0, column = 1)
    
25. Label(root, text = '=').grid(row = 0, column = 3)
    
26. 
    
27. # label1 = Label(root, text = '+')
    
28. # label1.grid(row = 0, column = 1)
    
29. # label2 = Label(root, text = '=')
    
30. # label2.grid(row = 0, column = 3)
    
31. 
    
32. mainloop()

这段代码运行后，出了一个异常，内容如下

1. Traceback (most recent call last):
   
2.   File "F:/Python source file/gui_in_tkinter/calculator/calculator.py", line 28, in <module>
   
3.     Label(root, text = '+').grid(row = 0, column = 1)
   
4.   File "E:\Python\lib\tkinter\__init__.py", line 2220, in grid_configure
   
5.     + self._options(cnf, kw))
   
6. _tkinter.TclError: cannot use geometry manager grid inside . which already has slaves managed by pack

我明明用的是grid方法啊，为什么它会说被pack管理了啊

你的frame用的pack
tk中不混用排版
