Bit operations

Hi,

my logic reaches the end. I have a bit mask defined and want following behavior when comparing FlagI and FlagII:

Code:

---

enum Flag
{
  A = 0x00000001,
  B = 0x00000002,
  C = 0x00000004,
  D = 0x00000008
};
Q_DECLARE_FLAGS(Flags, Flag)

---

Code:

---

//
        A  B  C  D
------------------
FlagI   1  0  0  1
FlagII  0  1  0  1
------------------
Result  0  1  0  0

---

But I can't figure it out since I am unable to distinguish between (FlagI-A:0 FlagII-A:1) and (FlagI-A:1 FlagII-A:0). Is that possible?


Thanks

NOT AGAIN! 5 minutes after posting I found the answer: ~FlagI & FlagII. (And that stupid thing coast me 40 minutes! Time for a break, I'm having a lunch now.)
