class FrameUI(wx.Frame):
  
    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 box containing above list
        self.rbox = wx.RadioBox(pnl, label ='RadioBox', pos =(80, 10), choices = lblList,
                              majorDimension = 1, style = wx.RA_SPECIFY_ROWS)
  
        # set help text for item at index 0
        self.rbox.SetItemHelpText(0, "First Item")
  
        # print helptext associated with item
        print (self.rbox.GetItemHelpText(0))
  
        # set frame in centre
        self.Centre()
        # set size of frame
        self.SetSize((400, 250))
        # show output frame
        self.Show(True)
