給Duilib的CTreeViewUI控制元件動態添加節點時順序不對引發的問題

給CTreeViewUI動態添加節點時發現了一個問題，如果

如果：

ptree->add（node1）

node1>add(node1-1)

node1>add(node1-2)

ptree->add（node2）

ptree->add（node3）

那么node1-1，node1-2會顯示不出來，調整添加順序為：

ptree>add（node1）

ptree>add（node2）

ptree>add（node3）

node1>add(node1-1)

node1>add(node1-2)

后就顯示出來了，這是受別的文章的啟發而試出來的，不得不說，開源的東西不好用，bug多，要猜著做，

真實的代碼如下，供參考：

            CTreeViewUI* pTree = static_cast<CTreeViewUI*>(m_PaintManager.FindControl(_T("tree_list")));
            if (pTree)
            {
                CTreeNodeUI *pTreeElement1 = new CTreeNodeUI;
                pTree->Add(pTreeElement1);
                pTreeElement1->SetItemText("111111");
                pTreeElement1->SetItemTextColor(RGB(0, 0, 0));
                pTreeElement1->SetItemHotTextColor(RGB(255, 255, 255));
                pTreeElement1->SetSelItemTextColor(RGB(255, 255, 255));
                pTreeElement1->SetAttribute(_T("folderattr"), _T("padding=\"0,1,0,0\" width=\"16\" height=\"16\" normalimage=\"res='155' restype='png' source='0,0,16,16' \" hotimage=\"file='155' restype='png' source='16,0,32,16' \" selectedimage=\"res='154' restype='png' source='0,0,16,16' \" selectedhotimage=\"res='154' restype='png' source='16,0,32,16' \""));
                pTreeElement1->SetAttribute(_T("checkboxattr"), _T("width=\"16\" height=\"16\" normalimage=\"res='125' restype='png'\" selectedimage=\"res='124' restype='png'\""));

                CTreeNodeUI *pTreeElement2 = new CTreeNodeUI;
                pTree->Add(pTreeElement2);
                pTreeElement2->SetItemText("22222222222");
                pTreeElement2->SetItemTextColor(RGB(0, 0, 0));
                pTreeElement2->SetItemHotTextColor(RGB(255, 255, 255));
                pTreeElement2->SetSelItemTextColor(RGB(255, 255, 255));
                pTreeElement2->SetAttribute(_T("folderattr"), _T("padding=\"0,1,0,0\" width=\"16\" height=\"16\" normalimage=\"res='155' restype='png' source='0,0,16,16' \" hotimage=\"file='155' restype='png' source='16,0,32,16' \" selectedimage=\"res='154' restype='png' source='0,0,16,16' \" selectedhotimage=\"res='154' restype='png' source='16,0,32,16' \""));
                pTreeElement2->SetAttribute(_T("checkboxattr"), _T("width=\"16\" height=\"16\" normalimage=\"res='125' restype='png'\" selectedimage=\"res='124' restype='png'\""));

                CTreeNodeUI *pTreeElement3 = new CTreeNodeUI;
                pTree->Add(pTreeElement3);
                pTreeElement3->SetItemText("333333333333333");
                pTreeElement3->SetItemTextColor(RGB(0, 0, 0));
                pTreeElement3->SetItemHotTextColor(RGB(255, 255, 255));
                pTreeElement3->SetSelItemTextColor(RGB(255, 255, 255));
                pTreeElement3->SetAttribute(_T("folderattr"), _T("padding=\"0,1,0,0\" width=\"16\" height=\"16\" normalimage=\"res='155' restype='png' source='0,0,16,16' \" hotimage=\"file='155' restype='png' source='16,0,32,16' \" selectedimage=\"res='154' restype='png' source='0,0,16,16' \" selectedhotimage=\"res='154' restype='png' source='16,0,32,16' \""));
                pTreeElement3->SetAttribute(_T("checkboxattr"), _T("width=\"16\" height=\"16\" normalimage=\"res='125' restype='png'\" selectedimage=\"res='124' restype='png'\""));

                CTreeNodeUI *pTreeElement11 = new CTreeNodeUI;
                pTreeElement1->AddChildNode(pTreeElement11);
                pTreeElement11->SetItemText("11111-1111111");
                pTreeElement11->SetItemTextColor(RGB(0, 0, 0));
                pTreeElement11->SetItemHotTextColor(RGB(255, 255, 255));
                pTreeElement11->SetSelItemTextColor(RGB(255, 255, 255));
                pTreeElement11->SetVisible(true);

                CTreeNodeUI *pTreeElement12 = new CTreeNodeUI;
                pTreeElement1->AddChildNode(pTreeElement12);
                pTreeElement12->SetItemText("11111-22222222222222");
                pTreeElement12->SetItemTextColor(RGB(0, 0, 0));

                pTreeElement12->SetItemHotTextColor(RGB(255, 255, 255));
                pTreeElement12->SetSelItemTextColor(RGB(255, 255, 255));
                pTreeElement12->SetVisible(true);
            }
