Hi, sorry for my chinese input method doesn' t  work now.

I'd like to delete and add some controls on wxPanel dynamically. I use
wxSizer.Detach() and Layout(), but it doesn't work at all, as the
following code shows. If the control(say self.btn) in sizer has nonzero
proportion, it works fine. But I wish the button stays non-expand, any
way ? or any wrong usage of sizer?

import wx
class Form1(wx.Panel):
    def __init__(self,parent,id):
        wx.Panel.__init__(self,parent,id)

        self.btn = wx.Button(self, -1, 'go')
        self.sizer = wx.BoxSizer(wx.VERTICAL)

        self.sizer.Add(self.btn)         ## it doesn't work
        # self.sizer.Add(self.btn, 1)    ## it works

        self.p1 = wx.StaticText(self, -1, 'ppp1')
        self.sizer.Add(self.p1)

        self.SetSizer(self.sizer)
        self.SetAutoLayout(True)

        self.btn.Bind(wx.EVT_BUTTON, self.onbtn)

    def onbtn(self,event):
        self.sizer.Detach(self.p1)
        self.sizer.Layout()

app = wx.PySimpleApp()
frame = wx.Frame(None, -1, "Test")
Form1(frame,-1)
frame.Show(1)
app.MainLoop()

在这里加上 self.p1.Destroy()

多谢，好用了，只是看起来有点儿闪动，有什么办法解决吗？
