ListView{

....
delegate: Rectangle {

	objectName: "rectangleDelegate"

//to get item and access the properies

function getItemAtIndex(index){
    var item = listViewId.itemAtIndex(index);
    if(item){

@galilio fair enough.

alright, trick 17 (untested)

ListView{
id: listViewId
objectName:"listViewObj"
var testObject: undefined
signal assignToObject(var id)
....
delegate: Rectangle {
	id: rectnagleId
	objectName: "rectangleDelegate"
        Connections{
             target: listViewId
             onAssignToObject: if(index === id) listViewId.testObject = rectnagleId
        }
	....
	}
}
//to get item and access the properies
        onTestObjectChanged:{
            if(testObject)
                console.log(testObject.objectName)
        }

@galilio
works fine in my test file

import QtQuick 2.12
import QtQuick.Window 2.12
import QtQuick.Controls 2.0

Window {
    visible: true
    width: 400
    height: 750
    title: qsTr("Hello World")

    id: root
    property int testIndex: 0
    Timer{
        running: true
        interval: 1000
        repeat: true
        onTriggered: {
            listViewId.assignToObject(root.testIndex)
            testIndex++
            if(testIndex >= 10)
                testIndex = 0
        }
    }

    ListView{
        id: listViewId
        anchors.fill: parent
        objectName:"listViewObj"
        property var testObject: undefined
        onTestObjectChanged:{
            if(testObject)
                console.log(testObject.objectName)
        }
        signal assignToObject(var id)

        model: 10
        spacing: 2

        delegate: Rectangle {
            id: rectnagleId
            objectName: "rectangleDelegate" + index
            Text {
                text: modelData
                anchors.centerIn: parent
            }
            width: listViewId.width
            height:  20
            color: "green"
            Connections{
                target: listViewId
                onAssignToObject: if(index === id) listViewId.testObject = rectnagleId
            }
        }
    }
}

@J-Hilk

and how is it if I want to test the delegate with unit test (in cpp) sorry

[Shivaraj]

@Galilio how do you access the objects using objectName can you share some code

[dheerendra]

@Shivaraj

Delegate you can't access using the object name. These are dynamically created object.
