using component's id in another QML

Hi..

Is it possible to use id of one component in QML file to another QML file?
if it is,then what is the way to use it?
please explain me with example.
its urgent.

Waiting for quick reply..

Thanks..

two use cases:

1. use outer items' id in inner item ...... yes
1. use inner items' id in outer item ...... no

for example:
A.qml
======
import "."
Item {
id:outer
B { id: inner } //B.qml
Component.onCompleted: {
//console.log(inner.invisibleId.x); //error
//console.log(inner.b.x); //error
}
}

B.qml
=====
Item {
id:b
Item { id: invisibleId}
Component.onCompleted: {
console.log(outer.x); //sucess: access outer item's id
}
}

Hi,

is there a simple way to access inner items' id in outer item ?
