wxpython + 更改面板和重做布局面板后非常小

Question

我通过破坏面板 1 然后显示面板 2 来更改我的面板。我不能使用创建两者和隐藏显示的方法，因为我还有其他问题。但是重做布局后，我的面板非常小。我怎样才能让它和以前一样大？

这是我的测试代码

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 ")
    self.btnChoose = wx.Button(self.Cellinfopanel, wx.ID_ANY, "Report")

    self.btnChooseCell = wx.Button(self.Cellinfopanel, wx.ID_ANY, " test3 ")
    self.btnChoose = wx.Button(self.Cellinfopanel, wx.ID_ANY, "test4")

if __name__ == '__main__':
app = wx.PySimpleApp()
MAview = Main(None, wx.ID_ANY)
MAview.Maximize()
MAview.Show()
app.MainLoop()

编辑：这与提议的问题不同。提题中，我用的是hide and show的方式，也有resizing的问题，就是panel太大了。我其实解决了另一个问题，我会添加答案。

Answer 1

这个 post 帮助我解决了我的问题 (http://forums.devshed.com/python-programming-11/wxpython-refreshing-panel-panel-392700.html)

加上

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

我的问题解决了。
