Tkinter 窗口组件：Checkbutton

是素素呀

from tkinter import *
master = Tk()

GIRLS = ["貂蝉","西施","王昭君","杨玉环"]

v = []

for girl in GIRLS:
    v.append(InVar())
    b = Checkbutton(master,text=girl,variable=v[-1])
    b.pack()
   
mainloop()

为什么我运行这个程序会报“NameError: name 'InVar' is not defined”这个错呢？

钱越来越少了

阳顺

.pack(anchor=w)

最后报错NameError: name 'w' is not defined


c = Checkbutton(root, text="加特技", variable=v).pack()
#c.var= v   #新建变量？

1. from tkinter import *
   
2. root = Tk()
   
3. 
   
4. Girls = ["xi shi","diao can","wang zhaojun","yang yuhuang"]
   
5. v = []
   
6. 
   
7. for i in Girls:
   
8.     v.append(IntVar())
   
9.     b = Checkbutton(root,text=i,variable=v[-1]).pack()
   
10.     #b.pack(side=LEFT)  一行并排
    
11.     #b.pack(anchor=w)  ?报错
    
12. 
    
13. 
    
14. v = IntVar()
    
15. 
    
16. c = Checkbutton(root, text="加特技", variable=v).pack()
    
17. c.var= v   #新建变量？
    
18. 
    
19. 
    
20. 
    
21. mainloop()
    

复制代码

AttributeError: 'NoneType' object has no attribute 'var'  为哈？

学了3个tk组件了，基本都是一样的，就像小甲鱼说的那样，认真学会一个就一通百通了

最好是明天

import tkinter as tk
from tkinter import ttk

app=tk.Tk()

v=tk.IntVar()
ttk.Checkbutton(app,font=('宋体',20,'bold'),text='我是复选',variable=v).pack()

app.mainloop()

错误：
Traceback (most recent call last):
  File "C:\Users\Administrator\Desktop\checkbutton  font.py", line 7, in <module>
    ttk.Checkbutton(app,font=('宋体',20,'bold'),text='我是复选',variable=v).pack()

这个该怎么解决啊！！！

创建复选框，同时获得选中的选项
names_list = ["wwx", "wxh", "yx", "hlh", "fzl", "lyb"]

v = []

for name in names_list:
    v.append(tk.IntVar())
    cb = tk.Checkbutton(master, text=name, variable=v[-1])
    cb.pack(anchor="w")

def showResult():
    print("选中的内容是：")
    for i in range(len(v)):
        if v[i].get() == 1:  # 判断该选项是否被选中
            print(names_list[i])


b = tk.Button(master, text="确定", command=showResult)
b.pack()
