[已解决]我想用循环来创建一个调节Text控件的字体大小，用这个回调函数后不能正确显示对应大小

太阳风暴

from tkinter import *
root = Tk()
root.geometry('400x300')

def Change_sizeof_character(size):
        All_text['font'] = ('',size)

Beautifulmenubar = Menu(root)
Charsizebar = Menu(Beautifulmenubar, tearoff = 0)
Beautifulmenubar.add_cascade(label = '字体大小', menu = Charsizebar)

for x in range(8,25):
        Charsizebar.add_command(label = x,command = lambda: Change_sizeof_character(x))

All_text = Text(root, bg = 'white')
All_text.pack(padx = 5,pady = 5)

root.config(menu = Beautifulmenubar)
root.mainloop()

事件参数传递方法不对，改正如下

1. from tkinter import *
   
2. 
   
3. root = Tk()
   
4. root.geometry('400x300')
   
5. 
   
6. def Change_sizeof_character(size):
   
7.     All_text['font'] = ('',size)
   
8. 
   
9. Beautifulmenubar = Menu(root)
   
10. Charsizebar = Menu(Beautifulmenubar, tearoff = 0)
    
11. Beautifulmenubar.add_cascade(label = '字体大小', menu = Charsizebar)
    
12. 
    
13. for x in range(8,25):
    
14.     Charsizebar.add_command(label = x,command = lambda size=x: Change_sizeof_character(size))
    
15. 
    
16. All_text = Text(root, bg = 'white')
    
17. All_text.pack(padx = 5,pady = 5)
    
18. 
    
19. root.config(menu = Beautifulmenubar)
    
20. root.mainloop()
