Adding characters to each line in a QString

I have a QString with a multi-line text without space at the begining like:

Lorem ispum   
Dolor a si met   
Hulu il it er

and I would like to add space to each line to obtain something like this:

      Lorem ispum  
      Dolor a si met   
      Hulu il it er

For information, I use QString of QT

You could use QString::replace() :

QString s = "Lorem ispum\nDolor a si met\nHulu il it er ";
s.replace(QRegExp("^"), "\t");

You could also do it without regular expression :

s.insert(0, '\t');
s.replace('\n', "\n\t");

This would add one tab (\t) at the beginning of each line, if you want to add spaces, just replace \t with spaces.

Just iterate over every character in the string, while copying to a second string. As soon as you see a newline then copy that and add the spaces needed.

Or simply use the replace function:

str.replace('\n', "\n\t");
