Can't assign QScreen to QML Window

[wost]

Doing some work with Qt now, but I'm stuck trying to figure out how to apply a screen to a QML Window element.

I'm doing this in the QML file

screen: app.getMonitor(this.screen);

and this corresponding function in CPP:

QScreen *getMonitor(QScreen* screen)
{
	QList<QScreen*> screens = screen->virtualSiblings();
	for(auto screen : screens) {
		qDebug() << "hi";
		qDebug() << screen->name();
	}
	return screens[1];
}

(The foreach loop is just for debugging purposes).
This doesn't work though. The program keeps saying:

Error: Unknown method return type: QScreen*

Have I misunderstood something. What else can I try?

#include <QScreen>

P.S.
Range base for loops with non-const Qt containes are not totally efficient, there is the chance you make them detach.

I have done that in the CPP file, but the problems seems to originate from the QML file.

I figured it out!

I used a function that set the screen for the window with a void function!
