검색해 보니 나오더군요 ^^;;;;;

그래서 대충 한칸 올리는건 했는데

똑같이 했는데 왜 한칸 내리는 건 안되는지 모르겠네요..

tr_ScanSide 가 TTreeView 콤포넌트의 이름입니다..

//================================================
void __fastcall TForm1::btn_UpClick(TObject *Sender)
{
        if(!tr_ScanSide->Selected)
                return;

        TNodeAttachMode AttachMode;
        TTreeNode *destNode, *selNode;
        if(tr_ScanSide->Selected->Index == 0)
                return;

        destNode = tr_ScanSide->Selected->GetPrev();
        selNode = tr_ScanSide->Selected;
        AttachMode = naInsert;
        selNode->MoveTo(destNode, AttachMode);


}
//---------------------------------------------------------------------------


void __fastcall TForm1::btn_DownClick(TObject *Sender)
{
        if(!tr_ScanSide->Selected)
                return;

        TNodeAttachMode AttachMode;
        TTreeNode *destNode, *selNode;
        if(tr_ScanSide->Selected->Index == tr_ScanSide->Items->Count)
                return;

        destNode = tr_ScanSide->Selected->GetNext();
