Example

import InCore.Foundation 2.5

Application {

    // Object Array with fixed elements - the usual way
    ObjectArray {
        id: objectArrayA
        Measurement {
            id: meas0
        }
        Measurement {
            id: meas1
        }
        onCompleted: console.log( "ObjectArray A ready with", objects.length, "objects" )
    }

    // ObjectArray with dynamic objects
    ObjectArray {
        id: objectArrayB
        Repeater on objects {
            model: 3
            Measurement {
                objectId: "id" + index
                data: index
            }
        }
        onObjectsChanged: console.log( "ObjectArray B has now", objects.length, "objects" )
    }

    // ObjectArray with elements of objectArrayA and objectArrayB
    ObjectArray {
        Gather on objects {
            source: ObjectArray {
                List { reference: objectArrayA.objects }
                List { reference: objectArrayB.objects }
            }
        }
        onObjectsChanged: console.log( "Combined list with", objects.length, "objects" )
    }
