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 .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？
from tkinter import *
root = Tk()
Girls = ["xi shi","diao can","wang zhaojun","yang yuhuang"]
v = []
for i in Girls:
v.append(IntVar())
b = Checkbutton(root,text=i,variable=v[-1]).pack()
#b.pack(side=LEFT)一行并排
#b.pack(anchor=w)?报错
v = IntVar()
c = Checkbutton(root, text="加特技", variable=v).pack()
c.var= v #新建变量？
mainloop()
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 {:10_256:} 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\checkbuttonfont.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.get() == 1:# 判断该选项是否被选中
print(names_list)
b = tk.Button(master, text="确定", command=showResult)
b.pack()
