wxPython和StaticBox(Sizer)问题

Question

最近，我对下面所示的代码有了问题，它已经困扰了我一段时间了。我不知道为什么会发生这种情况，我只知道python代码在注意到的行中会出现一个分段错误，而gdb会引发一些关于内存的内容。我是做错什么了还是这是个虫子？我真的很想把这个工作做好，所以如果你能帮忙的话，我会非常感激的。

C++代码：

static int win_width = 364;
static int win_height = 478;

netlist = new wxDialog(NULL, wxID_ANY, "Network List", wxDefaultPosition, wxSize(win_width-8, win_height-8), wxDEFAULT_DIALOG_STYLE|wxRESIZE_BORDER);

wxBoxSizer *hszr = new wxBoxSizer(wxHORIZONTAL),
  *vszr = new wxBoxSizer(wxVERTICAL), *vszr2 = new wxBoxSizer(wxVERTICAL);

wxStaticBoxSizer* sszr = new wxStaticBoxSizer(wxVERTICAL, netlist, "User Information");
wxFlexGridSizer* fgszr = new wxFlexGridSizer(2);

fgszr->Add(new wxStaticText(sszr->GetStaticBox(), wxID_ANY, "Nick Name: "));

Python代码：

win_width = 364
win_height = 478

netlist = wx.Dialog(None, wx.ID_ANY, "Network List", wx.DefaultPosition, wx.Size(win_width-8, win_height-8), wx.DEFAULT_DIALOG_STYLE|wx.RESIZE_BORDER)

hszr = wx.BoxSizer(wx.HORIZONTAL)
vszr = wx.BoxSizer(wx.VERTICAL)
vszr2 = wx.BoxSizer(wx.VERTICAL)

sszr = wx.StaticBoxSizer(wx.StaticBox(netlist, wx.ID_ANY, "User Information"), orient=wx.VERTICAL)
fgszr = wx.FlexGridSizer(2)

fgszr.Add(wx.StaticText(sszr.GetStaticBox(), wx.ID_ANY, "Nick Name: ")) # Segmentation Fault

在python方面，Add方法有以下参数：

Add(self, item, int proportion=0, int flag=0, int border=0, userData=None)

proportion不是一个id (但它会悄悄传递，因为它们都是整数)，而flag不是一个字符串。

与C++版本相比，一条工作路线是：

fgszr.Add(wx.StaticText(sszr.GetStaticBox(), wx.ID_ANY, "Nick Name: "))

更新：

以下代码使用wxPython 2.9.1.1在windows上成功执行

import wx

app = wx.PySimpleApp()

win_width = 364
win_height = 478

netlist = wx.Dialog(None, wx.ID_ANY, "Network List", wx.DefaultPosition, wx.Size(win_width-8, win_height-8), wx.DEFAULT_DIALOG_STYLE|wx.RESIZE_BORDER)

hszr = wx.BoxSizer(wx.HORIZONTAL)
vszr = wx.BoxSizer(wx.VERTICAL)
vszr2 = wx.BoxSizer(wx.VERTICAL)

sszr = wx.StaticBoxSizer(wx.StaticBox(netlist, wx.ID_ANY, "User Information"), orient=wx.VERTICAL)
fgszr = wx.FlexGridSizer(2)

fgszr.Add(wx.StaticText(sszr.GetStaticBox(), wx.ID_ANY, "Nick Name: ")) # Segmentation Fault

netlist.ShowModal()
