title: Add Notebook Page in wxpython
body: <p>I am running a wxpython application.  Within the application i have a panel that contains a notebook with some number of notebook pages/tabs.  On a button press (wx.button), i would like to be able to clear one of the notebook pages and replace it with new information provided in my GUI.  </p>
  
  <p>I have not seen any kind of Clear() function for wx.Notebook, so I had the thought of deleting the page and creating a new one.  However, I cannot seem to get this to work.  Here is my code...help??</p>
  
  <pre><code>def UpdatePanel(self):    
  
      self.Notebook3.DeletePage(0)
  
      self.newpage = scrolled.ScrolledPanel(self.Notebook3, -1)
      self.newpage.SetupScrolling()
      self.Notebook3.AddPage(self.newpage,"Page Inserted Here")
  
      # self.Notebook3.InsertPage(0,"Page Inserted Here")
  </code></pre>
