Re: wxNotebook and DeleteAllPages()

Sample attached.  This sample crashes when I call DeleteAllPages() on the 
button click.
Here is the code for reference:


import  sys
import  wx
#----------------------------------------------------------------------------
class MainFrame(wx.Frame):
  """"""
  #----------------------------------------------------------------------
  def __init__(self):
    """Constructor"""
    wx.Frame.__init__(self, None, title="Generic Notebook", size=(800,600))
    bSizer = wx.BoxSizer(wx.HORIZONTAL)

    self.testNotebook = wx.Notebook(self)
    nbPanel = wx.Window(self.testNotebook)
    self.testNotebook.AddPage(nbPanel, "test1")
    self.testNotebook.AddPage(nbPanel, "test2")
    self.testNotebook.AddPage(nbPanel, "test3")
    deleteButton = wx.Button(self, label="delete all then add page")
    deleteButton.Bind(wx.EVT_BUTTON, self.DeletePages)
    bSizer.Add(deleteButton,0,0)
    bSizer.Add(self.testNotebook,1,wx.EXPAND,10)
    self.SetSizer(bSizer)
    self.Show()
    return
  
  def DeletePages(self, event):
    self.testNotebook.DeleteAllPages()
    otherPanel = wx.Window(self.testNotebook)
    self.testNotebook.AddPage(otherPanel, "NewPanel")
    return

if __name__ == "__main__":
  app = wx.App(False)
  frame = MainFrame()
  app.MainLoop()
