SplashScreen implementation question

[ml16685]

Hello,

I have an embedded Qt application for Linux which has the following startup code:

int main(int argc, char *argv[])
{

   QApplication app(argc, argv);
// Startup actions neeeded to display AppView correctly
// Black screen is shown for several seconds
// ...

QQuickView AppView;
AppView.setSource(QUrl(QStringLiteral("main.qml")));
AppView.resize(480, 800);
AppView.show();
return app.exec();

}

I'd like to remove the black screen shown before AppView and to display QML animation
instead of it.

I see two possible options here but non of them is clear. Could you please advice
which one of them is more correct and also comment/answer the questions in each.

1. To display QSplashScreen at the beginnning of main().

int main(int argc, char *argv[])
{

QApplication app(argc, argv);
QSplashScreen *splash = new QSplashScreen();
splash->show();

// Startup actions neeeded to display AppView correctly
// Black screen is shown for several seconds
// ...  

}

The question here is what API to use to attach QML animation to QSplashScreen?
QSplashScreen inherits from QWidget, and so as I understand, no API like QQuickWidget::setSource() can be used.

2. To display another QQuickView at the beginnning of main() with attached QML animation.

int main(int argc, char *argv[])
{

QApplication app(argc, argv);
QQuickView SplashView;
SplashView.setSource(QUrl(QStringLiteral("SplashScreen.qml")));
SplashView.resize(480, 800);
SplashView.show();
app.exec();

// Startup actions neeeded to display AppView correctly
// Black screen is shown for several seconds
// ...

QQuickView AppView;
AppView.setSource(QUrl(QStringLiteral("main.qml")));
AppView.resize(480, 800);
AppView.show();

}

The question here is how to to close the SplashView and to display AppView on top of it?

Thanks

IMO save yourself some struggle and simply use a Loader QML element as your root item in the window.
Do not spawn multiple event loops, QML engines, etc.

@raven-worx Thank you, will try this approach.
