以下是 TListView.CustomSort 的使用例

function CustomQuickSort(Item1, Item2: TListItem; Data: Integer):
          integer; stdcall;
var
  Str1, Str2: string;
  I,J,K,L:Integer;
begin
  try
    if Data = -1 then 
    begin
      Str1 := Item1.Caption;
      Str2 := Item2.Caption;
    end 
    else 
    begin
      Str1 := Item1.SubItems[Data];
      Str2 := Item2.SubItems[Data];
    end;

    J := Length(Str1);
    K := Length(Str2);

    if J < K then 
    begin
      L := K - J;
      L := L - 1;
      for I := 0 to L do
        Str1 := '0' + Str1;
    end
    else 
    begin
      L := J - K;
      L := L - 1;
      for I := 0 to L do
        Str2 := '0' + Str2;
    end;

    Result := AnsiCompareStr(Str1, Str2);
    Result := 1 * Result; // Set direction flag.
  except
    Result := 0;  // If errors, say they are equal.
  end;
end;
