[SOLVED] QTextStream and std::endl

[Alterah]

Back again with another problem. Seems like this should be easy, but apparently I am doing something wrong. I am trying to write to a file. Here's the code:

@
void UsernamePopup::handleOkClicked()
{
QString username;
QString password;

QFile configFile("config.txt");

username = "Username | " + mUsernameEntry->text();

if(mPasswordEntry->text() == mPasswordCheckEntry->text())
{
    password = "Password | " + mPasswordEntry->text();

    if (configFile.open(QFile::WriteOnly))
    {
        QTextStream out(&configFile);

        out << username << std::endl << password << std::endl;
    }
    else
    {
        //Notify user
    }
}
else
{
   //Code to popup window notifying user
}

}
@

The error message I am getting is:
@
D:/Coding/QtProjects/SimChat-build-desktop/../SimChat/usernamepopup.cpp:126: error: no match for 'operator<<' in 'out.QTextStream::operator<<(((const QString&)((const QString*)(& username)))) << std::endl'@

I have looked at some examples online and even in the documentation. As far as I can tell I am doing what the examples show. Thanks for any assistance.

There's no operator<< overload for QTextStream that takes a @ostream &(*fun)(ostream &)@ (yes, that's a pointer to a function that takes a reference to ostream and returns a reference to a ostream). Which, by the way, is the type of std::endl.

But there's a nice operator<< overload for QTextStream that takes a @ QTextStream &(*fun)(QTextStream &) @ which is the type of QTextStream::endl.

Ok, I think I understand what you are saying. I changed the lined to:

@out << username << std::endl << password << std::endl;@

This compiles, but when I open the .txt file, It is all on one line in notepad. It does show a little "square" (looks like [])for where the newline should begin. However, Gedit for Windows shows them on separate lines. Part of me is wondering if I should just use ofstream instead of QFile, etc. Thanks.

Edit: Nevermind. This appears to be a quirk with Windows and "\r\n".

Are you sure you pasted the right line of code? It's the same as before...

About the "\r\n" terminator: simply open your QFile with the QIODevice::Text option.

Whoops, did not paste the correct line. Ought to be:

@out << "Username | " << username << endl << "Password | " << password << endl;@

And thanks for the advice. Worked like a charm.
