How to save any string in text file in Qt ?

[Pappu Kumar Keshari]

If I fetched data in (QString str ) str then I have to copy all the data which is in str to Copy.txt(Text File) file with file location. How Can I do it ?

@Pappu-Kumar-Keshari Please start here:

• https://doc.qt.io/qt-6/qfile.html
• https://doc.qt.io/qt-6/qtextstream.html - here you can even find example code for your use case

If you are attempting to store your string data in a file, then you can probably look at this example:

void save_to_file(QString filePath, QString data)
{
    if(filePath.isEmpty())
    {
        qDebug() << "File path is empty!"

        return;
    }

    QFile fileObject(filePath);

    if(!fileObject.open(QIODevice::WriteOnly))
    {
        qDebug() << "Error! could not open file."

        return;
    }

    QTextStream stream(&fileObject);

    stream << data;

    fileObject.close();
}

Hope this helps.
