C++ qrc file access

? Offline

Just want to clarify a detail here: with the FileIO::read(const QString& Url) method below, if I use a qrc path, I get an error. If I use a relative path (";/") it works. I didn't set a prefix for the qrc resources – I just use the default.

Can someone explain (for my Qt fatigued brain) what the difference here is and why the qrc path doesn't resolve to ":/"

thanks!

var readResult = fileio.read("qrc:/test.json"); // this doesn't work

var readResult = fileio.read(":/test.json"); // this does

QString FileIO::read(const QString& Url)
{
    m_source = Url;
    emit error(m_source);

    if (m_source.isEmpty()){
        emit error("source is empty");
        return QString();
    }

    QFile file(m_source);
    QString fileContent;
    if ( file.open(QIODevice::ReadOnly) ) {
        QString line;
        QTextStream t( &file );
        t.setCodec("UTF-8");
        do {
            line = t.readLine();
            fileContent += line;
        } while (!line.isNull());

        file.close();
    } else {
        emit error("Unable to open the file");
        return QString();
    }
    return fileContent;
}

@TOMATO_QT said:
I did wonder the same thing
and it seems to me that C++ use the ":/"
and QML
likes the "qrc:/"
I have seen code do
view->setUrl(QUrl("qrc:/dial.qml"));

So to make it ":/" it might need a to go though QUrl ?
Not tested, just pure speculation.
