Detect "is_on_top" in QML StackView. How?

[bogong]

Hello all!
I need to detect that the QML Object is on top of StackView. Is there any way to do it?
For example:

StackView {

	id: oStackView;
	width: parent.width;
	height: parent.height;

	Component.onCompleted: {
		oStackView.push(oScreenLogin);
	}

	Component {id: oScreenLogin; SScreenLogin {}}
	Component {id: oScreenSearch; SScreenSearch {}}
	Component {id: oScreenTest; SScreenTest {}}
}

I need to detect inside of oScreenLogin that it is on top of StackView. How to do it?

Solution found. Issue closed.
Inside of SScreenLogin:

property string pObjectName: "SScreenLogin";

id: oRoot;
objectName: oRoot.pObjectName;

And inside of JS script:

if (oStackView.currentItem.objectName == oRoot.pObjectName) {
	On top
} else {
	Not on top
}
