QT下int与QByteArray的转换
QByteArray intToByte(int number) { QByteArray abyte0; abyte0.resize(4); abyte0[0] = (uchar) (0x000000ff & number); abyte0[1] = (uchar) ((0x0000ff00 & number) >> 8); abyte0[2] = (uchar) ((0x00ff0000 & number) >> 16); abyte0[3] = (uchar) ((0xff000000 & number) >> 24); return abyte0; }
