CTreeCtrl两个对象拷贝！

[wxw_wjf]

实现的功能是，将一棵树的节点全部拷贝到另为一棵树里
请大家赐说说咋么弄！

弄懂拷贝构造函数就可以了。

[wxw_wjf]

这个个拷贝构造函数应该要重载的。
如果重载了拷贝构造函数，则赋值运算也得重载。
好麻烦的，有没有现在迭代一棵树，往另一棵树插入节点的。
请赐代码！

遍历树拷贝

我的代码如下：有死循环
void GisEMap::InitEmapTree()
{
m_cTreeCtrl.SetImageList(cTreeCtrl.GetImageList(TVSIL_NORMAL),TVSIL_NORMAL);
int itemCount = (int)cTreeCtrl.GetCount();
CString str= "";
str.Format("%d",itemCount);
GisLog::Write_GisLog("cTreeCtrl count=>"+str);


m_cTreeCtrl.DeleteAllItems();
//cTreeCtrl
CString sText;
TV_INSERTSTRUCT tvStruct;
//start insert root item
HTREEITEM hLocalTreeRootItem ;
HTREEITEM hGlolbalTreeRootItem = cTreeCtrl.GetRootItem();
tvStruct.item.hItem = hGlolbalTreeRootItem;
tvStruct.item.mask = TVIF_TEXT | TVIF_PARAM ;
cTreeCtrl.GetItem(&tvStruct.item);
sText = cTreeCtrl.GetItemText(hGlolbalTreeRootItem);
tvStruct.item.cchTextMax = sText.GetLength();
tvStruct.item.pszText = sText.LockBuffer();
tvStruct.hInsertAfter = TVI_ROOT;
tvStruct.hParent = TVI_ROOT;
hLocalTreeRootItem = m_cTreeCtrl.InsertItem(&tvStruct);
sText.ReleaseBuffer();
//end insert root item

RecursionTree(hGlolbalTreeRootItem);

/*
if(cTreeCtrl.ItemHasChildren(hGlolbalTreeRootItem))
{
HTREEITEM hChildItem = cTreeCtrl.GetChildItem(hGlolbalTreeRootItem);
HTREEITEM hInsertItem;
while(hChildItem!=NULL)
{
tvStruct.item.hItem = hChildItem;
tvStruct.item.mask = TVIF_TEXT |TVIF_PARAM;
cTreeCtrl.GetItem(&tvStruct.item);
sText = cTreeCtrl.GetItemText(hChildItem);
tvStruct.item.cchTextMax = sText.GetLength();
tvStruct.item.pszText = sText.LockBuffer();
tvStruct.hInsertAfter = hInsertItem;
tvStruct.hParent = hLocalTreeRootItem;
hInsertItem = m_cTreeCtrl.InsertItem(&tvStruct);
sText.ReleaseBuffer();


if(cTreeCtrl.ItemHasChildren(hChildItem)){
HTREEITEM hInsertNextItem;
HTREEITEM hNextChildItem = cTreeCtrl.GetChildItem(hChildItem);
while(hNextChildItem != NULL)
{
tvStruct.item.hItem = hNextChildItem;
tvStruct.item.mask = TVIF_TEXT |TVIF_PARAM;
cTreeCtrl.GetItem(&tvStruct.item);
sText = cTreeCtrl.GetItemText(hNextChildItem);
tvStruct.item.cchTextMax = sText.GetLength();
tvStruct.item.pszText = sText.LockBuffer();
tvStruct.hInsertAfter = hInsertNextItem;
tvStruct.hParent = hChildItem;
hInsertNextItem = m_cTreeCtrl.InsertItem(&tvStruct);
sText.ReleaseBuffer();
//hNextChildItem = NULL;
hNextChildItem = cTreeCtrl.GetNextItem(hNextChildItem, TVGN_NEXT);

// CString str = cTreeCtrl.GetItemText(hNextChildItem);
//GisLog::Write_GisLog("hNextChildItem text=>"+str);


}
}
hChildItem = cTreeCtrl.GetNextItem(hChildItem, TVGN_NEXT);

//hInsertItem = m_cTreeCtrl.InsertItem(groupIter->szGroupName,1,1,hLocalTreeRootItem,hInsertItem);
}

}
*/

//展开所有节点
MyExpandTree(m_cTreeCtrl.GetRootItem());

}

同枝的下一个节点是GetNextSiblingItem(hItem)这个函数，要是有死循环，说明有地方没取下一个节点

你可以使用XML来保存一个树的结构信息
