QTreeWidget nextSibling()

[user_mail07]

Q3ListView nextsibling ()method in QTreeWidget.

I am process of coverting Q3ListView and Q3ListItemView to QTreeWidget and QTreeWidgetItem recursively. But I can not find equivalent nextSibling( ) method in QTreeWidget. How do I iterate for next sibling?
CCheckListTreeItem is Q3CheckListItem
m_pListView is Q3ListView and now it is QTreeWidget

CCheckListTreeItem * pChild = (CCheckListTreeItem*) m_pListView ->firstChild();
 
	while(pChild)
	{
		if(pChild->isOn())
			strListIDS->append(pChild->text());
		pChild = (CCheckListTreeItem*)pChild->nextSibling();
	}

CCheckListTreeItem * pChild = (CCheckListTreeItem*) m_pListView ->firstChild();

	while(pChild)
	{
		if(pChild->isOn())
			strListIDS->append(pChild->text());
		pChild = (CCheckListTreeItem*)pChild->nextSibling();
	}
