How do I include a text file to a qt application?

I have text file from which I need to get data by line by line. So if my application is launched, it can read from the text file to show the information. But I don't want to supply my text file separately along with my application. How to do this? And well I have to d开发者_如何学运维o this using Qt!

I heard like using xml will be a better and easy way to accomplish this.

You have to add a qt resource file (.qrc) to your project

It might look like this:

<RCC>
    <qresource prefix="/">
        <file>file.xml</file>
        <file>files/file2.xml</file>
    </qresource>
</RCC>

After that you have to add that resource file to your project file (.pro)

Like this for example:

RESOURCES += myqrcfile.qrc

After that you can use that file in your code by using the character ':' to refer to the file

Maybe like this:

QFile data(":/file.xml");
//or
QFile data(":/files/file2.xml");
//etc...

Remember that the path that you define for the file(in the qrc) must correspond to the file's location in the filesystem as well.

Hope this helps, for more information I suggest you read the link to the documentation that Gorkem Ercan posted.

Qt Resource System is what you are looking for.

Such code works in the Qt 5.2 :

QResource common(":/phrases/Resources/Phrases/Common.xml");

QFile commonFile(common.absoluteFilePath());

if (!commonFile.open(QIODevice::ReadOnly | QIODevice::Text))
{
    qDebug() << "Unable to open file: " << commonFile.fileName() << " besause of error " << commonFile.errorString() << endl;

    return;
}

QTextStream in(&commonFile);

QString content = in.readAll();

Using QFile like that doesn't work (at least not in Qt 4.5), but you can use:

QResource r( ":/file.xml" );
QByteArray b( reinterpret_cast< const char* >( r.data() ), r.size() );
