How to add animation to a component while destroying in QML

pra7

I am adding Animation to my project and most of the UI is dynamic. Currently, i am not able to add animation to the Component while destroying. Following is the test application code which describes the same:

import QtQuick 2.9
import QtQuick.Window 2.2
import QtQuick.Controls 2.2

Window {
    visible: true
    width: 640
    height: 480
    title: qsTr("Hello World")

    property bool removeClicked : true

    Row{
        anchors.bottom: parent.bottom
        spacing:20
        Button{
            text:"Add"

            onClicked: {
                removeClicked = false
                comp.createObject(myrow)
            }
        }

        Button{
            id:remBtn
            text:"Remove"

            onClicked: {
                removeClicked = true
                myrow.children[0].destroy() //Destroy the object

            }
        }
    }

    Row{
        id:myrow
        height:40
        spacing:20
    }

    Component{
        id:comp
        Rectangle{
            width:20
            height:30
            color: "red"

            NumberAnimation on opacity{
                id: destroyAnimation
                from :removeClicked ? 1:0
                to: removeClicked ? 0:1
                duration: 1000
            }
        }
    }
}

Any help will be Appreciated!!!

Use model classes and views instead of such approach. It will save you a lot of tears in the long run.

For a starter, see: https://doc.qt.io/qt-5/qtquick-modelviewsdata-modelview.html
