wxpython +更改面板和重做布局面板后非常小

Question

我通过销毁面板1然后显示面板2来更改我的面板。我不能使用创建两者并隐藏en show的方法，因为比我有其他问题。但重做我的布局后，我的面板非常小。我怎样才能使它和以前一样大小？

这是我testcode

import wx 

class Main(wx.Frame): 
def __init__(self, parent=None, id=-1, notify_channel="chanMicroanalysis", **kwargs): 

    # general panel information 
    wx.Frame.__init__(self, parent, wx.ID_ANY) 
    self.SetTitle('Microanalysis') 
    self.backpanel = wx.Panel(self, wx.ID_ANY) 

    # first panel 
    self.Choicepanel = wx.Panel(self.backpanel, wx.ID_ANY) 

    self.lblChoose = wx.StaticText(self.Choicepanel, label="Choose:") 
    self.btnChooseFilterOnly = wx.Button(self.Choicepanel, wx.ID_ANY, "Filter only ") 
    self.btnChooseMA = wx.Button(self.Choicepanel, wx.ID_ANY, "Microanalyse") 
    self.btnChooseCellInfo = wx.Button(self.Choicepanel, wx.ID_ANY, " CellInfo ") 
    self.btnChooseReport = wx.Button(self.Choicepanel, wx.ID_ANY, "Report") 

    # second panel: cellinfo 
    self.test1 =wx.Panel(self.backpanel, wx.ID_ANY) 
    self.Cellinfopanel = self.test1 

    self.lblChooseingo = wx.StaticText(self.Cellinfopanel, label="Choose:") 
    self.btnChooseFilter = wx.Button(self.Cellinfopanel, wx.ID_ANY, "Filter only ") 
    self.btnChooseprr = wx.Button(self.Cellinfopanel, wx.ID_ANY, "Microanalyse") 
    self.btnChooseCell = wx.Button(self.Cellinfopanel, wx.ID_ANY, " CellInfo ")

编辑：作为建议这是不一样的问题。在提出的问题中，我使用了隐藏和显示方法，并且还存在调整大小的问题，但是面板很大。我实际上解决了另一个问题，我将添加答案。

这篇文章帮助我与我的问题（http://forums.devshed.com/python-programming-11/wxpython-refreshing-panel-panel-392700.html）

与添加

self.Fit() 
self.GetParent().SendSizeEvent() 

我的问题得到解决。
