How to create in memory QFile

[amleto]

Ok. For that, i think dont add the file in the resource folder,except that, directly create it in your project folder and access it from there. Because if you put your file in the resource and it will get compile and you'll not able to edit it. For that,

QFile *file;
file=new QFile("demo.txt");.
if (!file->open(QIODevice::WriteOnly | QIODevice::Text))
         return;
 
QTextStream out(file);
out << "The magic number is: " << 49 << "\n";
 
file->close(); //for closing the file.

QFile *file;
file=new QFile("demo.txt");.
if (!file->open(QIODevice::WriteOnly | QIODevice::Text))
         return;

QTextStream out(file);
out << "The magic number is: " << 49 << "\n";

file->close(); //for closing the file.

To copy to clipboard, switch view to plain text mode 

contains leaks...

Why put QFile on the heap at all?

If op wants to write/print QTextDocument, then he should familiarise himself with http://doc.qt.io/qt-4.8/qtextdocumentwriter
