怎么用递归或非递归的方式遍历treeview的所有item?

Question

我想从root开始遍历treeview中的所有item,如果发现是child item,则GetItemData。最好是非递归的方法
最好给出代码，谢谢了！

Answer 1

这种一般还是用递归遍历了，一层层找，找到item就判断一下是否为child，是就GetItemData

Answer 2

怎么遍历？我这样对吗：
void CBaseMemberManage::TravelTreeList(HTREEITEM hItem)
{
   HTREEITEM hTemp;
   hTemp = m_ctrlTree.GetNextItem(hItem,TVGN_CHILD);
   if(hTemp != NULL)
   {
      TravelTreeList(hTemp);
   }   hTemp = hItem;
   while( (hTemp = m_ctrlTree.GetNextItem(hTemp,TVGN_NEXT)) != NULL )
   {
       TravelTreeList(hTemp);
   }
   if(m_ctrlTree.GetCheck(hItem) && m_ctrlTree.GetParentItem(hItem) == NULL)
   {
   DWORD dwData =  m_ctrlTree.GetItemData(hItem);
   g_MyConnection.WriteLong(m_MemberInfoVector.at(dwData).GetShopUserId());
   g_MyConnection.WriteUTF(m_MemberInfoVector.at(dwData).GetMobileTel());
   }
}

Answer 3

while( (hTemp = m_ctrlTree.GetNextItem(hTemp,TVGN_NEXT)) != NULL )
{
       if(m_ctrlTree.GetCheck(hItem) && m_ctrlTree.GetParentItem(hItem) == NULL)
       {
           DWORD dwData =  m_ctrlTree.GetItemData(hItem);
           g_MyConnection.WriteLong(m_MemberInfoVector.at(dwData).GetShopUserId());
           g_MyConnection.WriteUTF(m_MemberInfoVector.at(dwData).GetMobileTel());
       }
       TravelTreeList(hTemp);
}
  

Answer 4

HTREEITEM hTemp;
   hTemp = m_ctrlTree.GetNextItem(hItem,TVGN_CHILD);
   if(hTemp != NULL)
   {
      TravelTreeList(hTemp);
   }   while( (hTemp = m_ctrlTree.GetNextItem(hTemp,TVGN_NEXT)) != NULL ) 
   { 
   if(m_ctrlTree.GetCheck(hItem) && m_ctrlTree.GetParentItem(hItem) == NULL) 
   { 
   DWORD dwData =  m_ctrlTree.GetItemData(hItem); 
   g_MyConnection.WriteLong(m_MemberInfoVector.at(dwData).GetShopUserId()); 
   g_MyConnection.WriteUTF(m_MemberInfoVector.at(dwData).GetMobileTel()); 
   } 
   TravelTreeList(hTemp); 
   } 
这样？ 发现还是有问题啊
