    Question Writing the text within a text edit to a file

    Hi all I have been trying to write to a text file. The code i currently have is:

    Qt Code:
    1. QString savelocation = ui->ComboBox->text();
    2. QFile ffile(savelocation + "/" + ui->lineEdit->text() + ".txt");
    3. if (ffile.open(QFile::WriteOnly)) {
    4. QTextStream out(&ffile);
    5. out << ui->textEdit->toPlainText();
    6. }
    To copy to clipboard, switch view to plain text mode 


    The data is being written to the file fine. However there are no return characters between the lines;
    e.g. if my text edit held:

    Qt Code:
    1. The Quick brown
    2. Fox jumped over
    3. The lazy dog
    To copy to clipboard, switch view to plain text mode 

    it would be written to the file like this:

    Qt Code:
    1. The Quick brown Fox jumped over The lazy dog
    To copy to clipboard, switch view to plain text mode 

    How do i solve this problem

    Thanks for your time and trouble

    I believe you can turn line wrap (or wordwrap policy) off, forcing you to use line ends.

    Also look at QTextDocument::textWidth(). You can use an underlying QTextDocument with QTextEdit.

    You may try using QIODevice::Text flag when opening the file:
    Qt Code:
    1. ffile.open(QIODevice::WriteOnly | QIODevice::Text)
    To copy to clipboard, switch view to plain text mode 
    From the docs (about QIODevice::Text):
    When writing, the end-of-line terminators are translated to the local encoding, for example '\r\n' for Win32.
