Using 2 different Panel in a notebook page

Hello!

I am pretty new with wxPython.

I am working with a splitted frame :
on left side 2 buttons,
    myButton1 = wx.Button(myLeftSplitter, ...)
    myButton2 = wx.Button(myLeftSplitter, ...)
    self.Bind(wx.EVT_BUTTON, self.OnClick1, myButton1)
    self.Bind(wx.EVT_BUTTON, self.OnClick2, myButton2)

on the right side a notebook that only contains one page. That page contains a panel
    myNotebook = wx.Notebook(myRightSplitter, ...)
    myDefaultPanel = wx.Panel(myNotebook, ...)
    myNotebook.AddPage(myDefaultPanel, ..., "My Absolutely Single Page")

I would like a click on myButton1 to replace myDefaultPanel by myNewPanel in "My Absolutely Single Page"
    def OnClick1(self, event):
       Change myDefaultPanel to myNewPanel in "My Absolutely Single Page"

Then a click on myButton2 should do the way back
    def OnClick2(self, event):
       Change myNewPanel to myDefaultPanel in "My Absolutely Single Page"

I don't manage to get any result. I tried various way but ... !

Thank you for your help !
