how to convert an int to QByteArray

hi
how to convert an int to QByteArray

Here's a quick, untested solution:

Code:

---

for(int i = 0; i != sizeof(n); ++i)
{
  byteArray.append((char)(n&(0xFF << i) >>i));
}

---

n is the integer you want to store in the byte array.

Notice static methods of QByteArray.

always u think the person who ask question is lazy and just want him to search the entire manual;)

I don't think so, because there's no way he could've given you the link directly to the static members section in the QByteArray documentation. There's no link to that section.

Huh? Entire manual? Is it so hard to find static members of QByteArray? :) In the end, by giving hints rather than direct links, you'll get more familiar with the docs and learn searching them by yourself.

cool marcel
i didn,t mean seriously ,in fact the post was useful and i have even thanked him.

what i meant was he could have(not necessarily) directly pasted this line .
QByteArray QByteArray::number ( int n, int base = 10 )

Dude that's not correct. it should be:

Code:

---

for(int i = 0; i != sizeof(n); ++i)
{
    byteArray.append((char)((n & (0xFF << (i*8))) >> (i*8)));
}

Why not ???
Check here :)

I am sure that nearly seven years after the original post, this information will prove to be just the answer the original poster was asking for. Don't you guys ever bother to check the post dates before replying to something?

No, never happens. Everything on the Internet is true, but some things are more true than others.

Code:

bool operator>(bool lhs, bool rhs) { return true; }
