wxPython clear panel

[Robbert]

Hi,

I could do with some help with how to clear a panel(self.panel1) so the new buttons load in a new/clean panel(self.panel1) in the following code when either "Button One" or "Button Two" has been selected at the top of the frame.

I have tried everything I could think of and searched for but i just can't sort it. Thanks very much for any help offered - cheers.

import wx
from wx.lib.buttons import GenBitmapTextButton

        wx.Frame.__init__(self, parent, -1, frameTitle, size=frameSize)
        self.Center()

        self.CreateLayout()
        self.CreateButtons()


    def CreateButtons(self):
        sizer = wx.BoxSizer(wx.VERTICAL)

        myList = ([(GenBitmapTextButton(self.panel3, 10, wx.Bitmap('image.png'), 'Button One', (0, 0), (150, 30))),
                    (GenBitmapTextButton(self.panel3, 11, wx.Bitmap('image.png'), 'Button Two', (150, 0), (150, 30)))])
 
        gs = wx.GridSizer(2, 1, 3, 3)
        gs.AddMany(myList)

        print countArray
        self.panel3.buttons = wx.Panel(self.panel3, -1, size=(20, int(countArray*150)))
