    def __init__(self, parent, title):
        super(FrameUI, self).__init__(parent, title = title, size =(300, 200))
  
        # function for in-frame components
        self.InitUI()
  
    def InitUI(self):
        # parent panel for radio box
        pnl = wx.Panel(self)
  
        # list of choices
        lblList = ['Radio One', 'Radio Two']
  
        # create radio boc containing above list
        self.rbox = wx.RadioBox(pnl, label ='RadioBox', pos =(80, 10), choices = lblList,
                                         majorDimension = 1, style = wx.RA_SPECIFY_COLS)
  
        # print total items in radio box
        print (self.rbox.GetCount())
  
  
        # set frame in centre
        self.Centre()
        # set size of frame
        self.SetSize((400, 250))
        # show output frame
        self.Show(True)
  
  
# wx App instance
ex = wx.App()
# Example instance
