Qt / Qml for two different displays on the QNX platform

I am trying to create a Qt application rendering for two displays. QNX is already configured for two displays. We created two windows, but how can we tell Qt to display the window on a second display?

Here is my code snippet

QGuiApplication app(argc, argv);

QtQuick2ApplicationViewer viewer1;
QtQuick2ApplicationViewer viewer2;

init();

viewer1.setMainQmlFile(QStringLiteral("qml/VisionBuck/main.qml"));
viewer1.showExpanded();

viewer2.setMainQmlFile(QStringLiteral("qml/VisionBuck/display2.qml"));
viewer2.showExpanded();

At the output, I can see 2 windows displaying QML. But they are displayed on one display. How to attach windows to different screens?

QtQuick2ApplicationViewerinherits from QQuickViewand therefore from QWindow. Thus, you can adjust the screen for each of the viewers:

viewer1.setScreen(app.screens().first());
viewer2.setScreen(app.screens().last());
