如何在SOUI窗口中动态创建新的SWindow？

SWindow *pWnd = new SWindow();
FindChildByName(L"xxx")->InsertChild(pWnd);

 1  SWindow * SWindow::CreateChildren(LPCWSTR pszXml)
 2     {
 3         pugi::xml_document xmlDoc;
 4         if(!xmlDoc.load_buffer(pszXml,wcslen(pszXml)*sizeof(wchar_t),pugi::parse_default,pugi::encoding_utf16)) return NULL;
 5         BOOL bLoaded=CreateChildren(xmlDoc);
 6         if(!bLoaded) return NULL;
 7         else return m_pLastChild;
 8     }
 9 
10     BOOL SWindow::CreateChildren(pugi::xml_node xmlNode)
11     {
12         TestMainThread();
13         for (pugi::xml_node xmlChild=xmlNode.first_child(); xmlChild; xmlChild=xmlChild.next_sibling())
14         {
15             if(xmlChild.type() != pugi::node_element) continue;
16 
17             if(_wcsicmp(xmlChild.name(),KLabelInclude)==0)
18             {//在窗口布局中支持include标签
19                 SStringT strSrc = S_CW2T(xmlChild.attribute(L"src").value());
20                 pugi::xml_document xmlDoc;
21                 SStringTList strLst;
22 
23                 if(2 == ParseResID(strSrc,strLst))
24                 {
25                     LOADXML(xmlDoc,strLst[1],strLst[0]);
26                 }else
27                 {
28                     LOADXML(xmlDoc,strLst[0],RT_LAYOUT);
29                 }
30                 if(xmlDoc)
31                 {
32                     CreateChildren(xmlDoc.child(KLabelInclude));
33                 }else
34                 {
35                     SASSERT(FALSE);
36                 }
37             }else if(!xmlChild.get_userdata())//通过userdata来标记一个节点是否可以忽略
38             {
39                 SWindow *pChild = SApplication::getSingleton().CreateWindowByName(xmlChild.name());
40                 if(pChild)
41                 {
42                     InsertChild(pChild);
43                     pChild->InitFromXml(xmlChild);
44                 }
45             }
46         }
47         
48         return TRUE;
49     }
