Read/Write from QTextStream

[tonde]

Thanks. I missed that seek() function completely. Implementing seek() to the QByteArray case seems to be working.

example:

QString buffer = "funny world";
 
QByteArray array;
array.append(buffer);
QTextStream out(&array,QIODevice::ReadWrite);
 
//out.pos() == 0 
out << "hello"; //"hello" overwrites "funny"
 
out.seek(0); // set position to 0
 
QString string;
QString string2;
 
// stream == "hello world"
// QTextStream reads into strings word by word delimited by space
out >> string; // == "hello" 
out >> string2; // == "world"

QString buffer = "funny world";
	
QByteArray array;
array.append(buffer);
QTextStream out(&array,QIODevice::ReadWrite);
	
//out.pos() == 0 
out << "hello"; //"hello" overwrites "funny"
	
out.seek(0); // set position to 0
	
QString string;
QString string2;

// stream == "hello world"
// QTextStream reads into strings word by word delimited by space
out >> string; // == "hello" 
out >> string2; // == "world"

can we use the seek function with a delimiter?

e.g. |word1|word2|....
with delimiter "|"

No, you have to use QString::indexOf() or similar method.
