Pass object like property into QML Component. How?

[bogong]

Hello all!
Is there option to pass object into QML Component? For example:

CustomItem.qml

CustomItem {
    property SomeType object: objectID;
    ...
    Component.onCompleted: {
        objectID.someMethod();
    }
}

any other qml where used CustomItem.qml

...
Item {
    id: AnyObject;
    ...
}

CustomItem {
    object: AnyObject;
}

The use-case for it looks like - ability to define any other object by ID inside of QML from outside through property. Is it possible?

Solution found.

CustomItem.qml

CustomItem {
    property var object;
    ...
    Component.onCompleted: {
        if (object) {object.someMethod();}
    }
}

any other *.qml

...
Item {
    id: AnyObject;
    ...
}

CustomItem {
    object: AnyObject;
}

Short answer is "Yes". But you should be sure in your case if object property is valid and contains someMethod. Simple example:

ApplicationWindow {
    id: root
    visible: true
    width: 400
    height: 680

    Item {
        id: item
        function a() { console.log("a"); }
    }

    Item {
        id: item2
        property Item customprop: null

        onCustompropChanged: {
            console.log("customprop changed");
            customprop.a();
        }
    }

    Component.onCompleted: {
        item2.customprop = item
    }
}

I understand it because there are no protocol or interface functionality in QML.
