writing in text file

function::

Code:

---

QFile file("input.txt");
file.open(QIODevice::WriteOnly);
QDataStream out(&file);   
out << QString("somedata");

---

I have been able to write in text file with this....
but when I want to add another thing in same text file whenever I call the function for next time .....my previous value gets erased....on text file ,,and i don't want the data to be erased...
please suggest me how to solve this problem??

Did you try QIODevice::Append ?

No I didn't ...and I have very little idea about this...
would you please mind elaborating this??

Something like:

Code:

---

file.open(QIODevice::WriteOnly | QIODevice::Append);
