Hi 各位达人：

请看我的代码，我想鼠标点击Radiobutton的时候，可以把选择的button通过回调的方式在selected的方法中打印出来？现在回调时没有问题，但是我怎么知道那个是被选中的那？

还是Tk的时间模型不是这样的，应该用bind方法？但是我看doc里面Radiobutton没有bind的方法啊？还有问一下Tk里面不断的用TopLevel是为什么，我不太理解

代码如下：

#Driver examination

from Tkinter import *

class Question:

def __init__(self, title, answer, linearray):

"""Create new Question. linearray is question line array object. """

self.title = title

self.answer = answer

self.linearray = linearray

def isright(self, answer):

"""Inpute answer is right, 'A', 'B', 'C"""

return self.answer==answer

class QuestionPanel(Frame):

def __init__(self, master):

Frame.__init__(self, master)

self.top = master

# self.question = question

def validateAnswer(self, question):

""" Validate input answere is right"""

Label(self.top, text="You're right!!").grid(row=(question.linearray.__len__))

def selected(self, event=None):

print event

def randerQuestion(self, question):

"""Display spec quesiton on Window"""

# font = Font(size=12)

Label(self.top, text=question.title).pack(anchor=W)

count =1

v = IntVar()

for line in question.linearray:

Radiobutton(self.top, text=line, variable=v, value = line[0], command=self.selected).pack(anchor=W)

# count = count+1

question = Question("What's your age?","C",['A, 28','B, 29','C, 30'])

root = Tk()

#v = IntVar()

#for x in question.linearray:

# Radiobutton(root, text=x, variable = v, value=x[0]).pack(anchor=W)

questionPanel = QuestionPanel(root)

questionPanel.randerQuestion(question)

#QuestionPanel.validateAnswer(question)

#print "Size:", question.linearray.index

root.mainloop()

#for x in question.linearray:

# print x

#print 'Pls select one answer'

#print question.isright('A')
