New File

Hello,

I would like to create a new empty text file. The user should type in a name of the file and perhaps write in some text then press save to create a file at a given place.

I can write and read from a file. But I need some help with creating new files. I have tried to work with QTextDocumentWriter and QTextDocumentFragment, and it's not going so well.. I also wonder about setDevice, what should I set it to?

void MainWindow::on_pushButton_clicked() {

QString fileName = ui->lineEdit->text();
QFile fil("C:/Users/" + fileName + ".txt");

QString writtenToFile = ui->textEdit->toPlainText();
QTextDocumentWriter writer(&fil, "plaintext");

writer.setFormat("txt");
writer.setFileName(fileName);
// writer.setDevice?

writer.write(QTextDocumentFragment::fromPlainText(writtenToFile));

}


I am very happy for all of your help.

"txt" is not a valid format - read this
http://doc.qt.nokia.com/4.7-snapshot/qte…DocumentFormats

Why instantiate QTextDocumentWriter with a QFile and then ALSO specify the filename?

"I also wonder about setDevice, what should I set it to?"
Nothing. Don't do anything with it.

QString filename = "C:/users/"
filename += ui->lineEdit->text();
filename += ".txt";
QTextDocumentWriter writer(filename);
writer.write(ui->textEdit->document());
If you have a problem, CUT and PASTE your code. Do not retype or simplify it. Give a COMPLETE and COMPILABLE example of your problem. Otherwise we are all guessing the problem from a fabrication where relevant details are often missing.
