I have a simple v-play app running with the following code under Debian 8/64 Felgo 2.61. The app works but i see the splash screen popping up twice. running the same code built with a qtquick does not show this. can someone show me what is wrong

V-play cpp

int main(int argc, char *argv[])
{
    QApplication app(argc, argv);
    VPApplication vplay;

    // Use platform-specific fonts instead of Felgo's default font
    vplay.setPreservePlatformFonts(true);

    // QQmlApplicationEngine is the preferred way to start qml projects since Qt 5.2
    // if you have older projects using Qt App wizards from previous QtCreator versions than 3.1, please change them to QQmlApplicationEngine
    QQmlApplicationEngine engine;
    vplay.initialize(&engine);

    // use this during development
    // for PUBLISHING, use the entry point below
    vplay.setMainQmlFileName(QStringLiteral("qml/Main.qml"));

    // use this instead of the above call to avoid deployment of the qml files and compile them into the binary with qt's resource system qrc
    // this is the preferred deployment option for publishing games to the app stores, because then your qml files and js files are protected
    // to avoid deployment of your qml files and images, also comment the DEPLOYMENTFOLDERS command in the .pro file
    // also see the .pro file for more details
    //play.setMainQmlFileName(QStringLiteral("qrc:/qml/Main.qml"));
    // main.cpp

    engine.load(QUrl(vplay.mainQmlFileName()));

    QQmlComponent component(&engine, "qml/Main.qml");
    QObject *object = component.create();
    QVariant returnedValue;
    QVariant msg = "Hello from C++";
    QMetaObject::invokeMethod(object, "myQmlFunction",
            Q_RETURN_ARG(QVariant, returnedValue),
            Q_ARG(QVariant, msg));

    qDebug() << "QML function returned:" << returnedValue.toString();
    delete object;

    return app.exec();
}

vplay qml main.qml

import Felgo 3.0
import QtQuick 2.5

App     {
    width: 640
    height: 480

    function myQmlFunction(msg) {
        console.log("Got message:", msg);
        return "some return value fromm qml";
    }
}

Hi Cal!

I tried the code you provided and didn’t run into your problem. (at least on MacOS – I have yet to test it on Linux)
Does the SplashScreen problem also occur when you try the Empty Felgo Apps Project from the Project Wizard – or does it only happen with your code?

Best,
Günther

I tried your suggestion and i did not see a second splash screen.

i just can’t see why a see 2 here. would you like the complete src???

Hi Cal,

Yes, please send your source to support@felgo.com!

Hi,
I have the same problem but no solution so far:

    ...

    engine.load(QUrl(vplay.mainQmlFileName()));

    QQmlComponent component(&engine, "qml/StackTheBoxMain.qml");
    QObject *object = component.create();
    //do something with object
    delete object;

    return app.exec();
}

This is from the main.cpp of the ‘StackTheBox’ example. A second screen appears if I add the 3 lines in the middle of the code.

Hi Sarevok!

The StackTheboxMain.qml item is a GameWindow, which is derived from the QML ApplicationWindow type.
Creating a new instance then means creating a new window. You would see the same behavior with a standard Qt Quick Application when creating a new window instance of the qml window in the main.cpp.

Best,
Günther
