import wx
app = wx.App()
win = wx.Frame(None,title="Simple Editor",size=(410,335))
bkg = wx.Panel(win)
loadButton = wx.Button(bkg,label='Open')
saveButton = wx.Button(bkg,label='Save')
fileName = wx.TextCtrl(bkg)
contents = wx.TextCtrl(bkg,style=wx.TE_MULTILINE|wx.HSCROLL)
hbox = wx.BoxSizer()
hbox.Add(fileName,proportion=1,flag=wx.EXPAND)
hbox.Add(loadButton,proportion=0,flag=wx.LEFT,border=5)
hbox.Add(saveButton,proportion=0,flag=wx.LEFT,border=5)
vbox = wx.BoxSizer(wx.VERTICAL)
vbox.Add(hbox,proportion=0,flag=wx.EXPAND | wx.ALL,border=5)
vbox.Add(contents,proportion=1,
flag=wx.EXPAND | wx.LEFT | wx.BOTTOM | wx.RIGHT,border=5)
bkg.SetSize(vbox)
win.Show()
app.MainLoop()
程序代码如上
窗口一闪而过，不知道问题出在哪里。
系统是win764位，python2.7，wxPython2.8-win64-unicode-2.8.12.1-py27，eclipse

代码仔细点
bkg.SetSize(vbox)→bkg.SetSizer(vbox)
少了个“r”
