io - Writing single bytes to a QDataStream -

i want write series of bytes qdatastream. when viewed in hex editor, i'd resulting file this:

0x dead 

my attempt looks this:

qfile file("test.txt"); file.open(qiodevice::writeonly); qdatastream stream(&file); stream << ((char)0xde); stream << ((char)0xad); file.close(); 

when open test.txt hex editor, can see instead of writing these single bytes, datastream has left-padded them full words, , file looks this:

0x ffff ffde ffff ffad 

what's right way this?

the qiodevice left-shift operator (<<) doesn't have overloaded definition char primitive, cast int.

it have definition qint8 type. changing code fixes output:

stream << ((qint8) 0xde); stream << ((qint8) 0xad);
