wxpython SplitterWindow panel 刷新后不能正确显示的问题？，,现在用wxpython

现在用wxpython 做联系人应用，希望实现点击左侧联系人列表刷新右侧联系人信息现在使用了wx.SplitterWindow， ReplaceWindow(winOld, winNew)现在点击实现了替换，返回了True 。但是替换后不能在右侧显示。SplitterWindow 部分代码：

class SplitterContacts(wx.SplitterWindow):                                          def __init__(self, parent, ID):                                                     wx.SplitterWindow.__init__(self, parent, ID,                                        style = wx.SP_LIVE_UPDATE)                                              self.sp = wx.SplitterWindow(self)                                               self.InitSplitter()                                                         def InitSplitter(self):                                                             self.SetSize((500, 500))                                                        style = wx.BORDER_SUNKEN                                                        with open('contacts.json', 'r') as contacts:                                        contacts = contacts.read()                                                  contacts = json.loads(contacts)                                                 contact = contacts.values()[0]                                                  left_list = wx.Panel(self, style=style)                                         left_list = ListContactsPanel(self, style=style, contacts=contacts)             left_list.SetBackgroundColour("sky blue")                                       right_list = ContactDetail(self, style=style, contact=contact)                  right_list.SetBackgroundColour("pink")                                          self.SetMinimumPaneSize(200)                                                    self.SplitVertically(left_list, right_list, -400)

点击响应事件 处理

def OnColClick(self, evt):                                                      i = evt.GetIndex()                                                          contact = self.contacts.values()[i]                                         left = self.parent.GetWindow1()                                             old = self.parent.GetWindow2()                                              old.SetBackgroundColour("blue")                                             style = wx.BORDER_SUNKEN                                                    new = ContactDetail(self, style=style, contact=contact)                                                                             self.parent.ReplaceWindow(old, new)      old.Destroy()                                     new.Show(True)  

不知道哪里出了错误！请教一下谢谢！
