int main(int argc, char *argv[])
{
#if QT_VERSION < QT_VERSION_CHECK(6, 0, 0)
    QCoreApplication::setAttribute(Qt::AA_EnableHighDpiScaling);
#endif
    QGuiApplication app(argc, argv);
    QQmlApplicationEngine engine;
    if(QFontDatabase::addApplicationFont(QLatin1String(":/iconfont.ttf"))==-1)
    {
        qDebug()<<"load font failed";
    }
//查询字体库名称
    QFontDatabase qfd;
    QStringList qsl = qfd.families();
    qDebug()<<qsl;
    const QUrl url(QStringLiteral("qrc:/main.qml"));
    QObject::connect(&engine, &QQmlApplicationEngine::objectCreated,
                     &app, [url](QObject *obj, const QUrl &objUrl) {
        if (!obj && url == objUrl)
            QCoreApplication::exit(-1);
    }, Qt::QueuedConnection);
    engine.load(url);

    return app.exec();
}

                    font.pointSize:  20
                    text: "\ue889"
                    anchors.centerIn: parent
