    def __init__(self, *args, **kwargs):
        super(Example, self).__init__(*args, **kwargs)
  
        self.InitUI()
  
    def InitUI(self):
        self.pnl = wx.Panel(self)
        self.btn = wx.Button(self.pnl, label ='Button', pos =(20, 20))
        self.btn.SetAuthNeeded(True)
  
        # PRINT IF AUTHENTICATION IS NEEDED OR NOT USING GetAuthNeeded()
        if(self.btn.GetAuthNeeded()== True):
            print("Authentication is needed.")
        else:
            print("No Authentication is needed.")
        self.SetSize((350, 250))
        self.SetTitle('wx.Button')
        self.Centre()
  
def main():
    app = wx.App()
    ex = Example(None)
    ex.Show()
