    Description

      now QFlags use int type as storage,means that we can only declare up to 32 flags，when we need more than 32 flags, although we can define enumerations like this：

      enum Option : quint64
{
         Option1 = 0x1,
         Option2  = 0x2,
          …………
          Option64 = 0x8000000000000000
};

      But we can't use Q_DECLARE_FLAGS and Q_DECLARE_OPERATORS_FOR_FLAGS to define flags.
