在一个框架中的多个面板的错误WXPYTHON

Question

我有3个面板在1帧的功能onSwitchPanels带我从面板到面板，知道我想做一个检查，如果这个检查是好的，那么我想SwitchPanels有问题，我堆栈什么我做错了（对不起，我的英语）

任何人都可以帮助吗？

的代码如下：

 import wx 
    import wx.grid as gridlib

      button =wx.Button(self, label="Save", pos=(200, 0)) 
      button.Bind(wx.EVT_BUTTON, self.Check) 

     def Check(self,event):
