Access object property in JS

I've created a couple of my own objects, container and item
Items are movable and periodically I check for some condition, let's say fot objects intersection.
If required event occurs, the object emits a signal:

Code:

---

class Container : public QQuickItem {
public:
	void checkIntersection() {
		foreach (QObject *child, childItems()) {
			if (MyObject *obj = dynamic_cast<MyObject*>(child)) {
				... 
				if(intersected(obj,other_obj)) emit intersect(other_obj);
			}
		}
	}
	bool intersected(MyObject * obj,MyObject * other) {
		...
		return true;
	}
signals:
	intersect(MyObject * other);	
}
 
class MyObject : public QQuickItem {
	...
}

---

and QML structure for better understanding:

Code:

---

Container {
	MyObject {
		id: object1
		...
		onIntersect: {
			if(other.id === "object2") { // error, id is undefined
				doSomething();
			}
		}
	}
	MyObject {
		id: object2
		...
	}	
}

---

As you can see, when I trying to get object property (id) I get error. I can read some properties, width or height for example, but id is inaccesible.
What I do wrong?

I think you can do

Code:

---

other == object2

---

i.e. using the id like a reference to the object

Another option would be to set the "objectName" property and compare with that.
