    self.diskList = ['3','4','5']
    self.cB = wxComboBox(self,-1,wxDefaultPosition,wxDefaultSize,self.diskList)

    The code is executed initially.
    If i want to update only the diskList, what could i do?

    I take it you want the list and the wxComboBox tied together so that
    updating the python list automatically updates the wxComboBox. There is
    no built-in way to do this. However, you could do something like this:

    import wx

    class CBList(list):
    def __init__(self, combobox):
    self.combobox = combobox

    def __setitem__(self, key, value):
    list.__setitem__(self, key, value)
    self.combobox.SetString(key, value)

    def __delitem__(self, key):
    list.__delitem__(self, key)

    def append(self, value):
    list.append(self, value)

    class MyFrame(wx.Frame):
    def __init__(self, parent, id, title):
    wx.Frame.__init__(self, parent, id, title)
    cb = wx.ComboBox(self, -1)
    choices = CBList(cb)

    choices.append('test 1')
    choices.append('test 2')
    choices[0] = 'replace test 1'
    del choices[1]

    if __name__ == '__main__':
    app = wx.PySimpleApp()
    frame = MyFrame(None, -1, 'test')
    app.MainLoop ()
