An example of real-time TableView in QML

Looks like CheckBox-es respond to clicks and work correctly even if they are in a TableView that is updated once a second:

See QML source code below:

import QtQuick
import QtQuick.Window
import QtQuick.Controls
import QtQuick.Layouts

Window {
    width: 640
    height: 480
    visible: true
    title: qsTr("Real-time TableView")

    ListModel
    {
        id: list
    }

    ColumnLayout
    {
        spacing: 5

        anchors.fill: parent

        TableView
        {
            id: table
            model: list
            columnSpacing: 5
            rowSpacing: 3
            clip: true
            Layout.fillWidth: true
            Layout.fillHeight: true
            Layout.margins: 10

            ScrollBar.horizontal: ScrollBar{}
            ScrollBar.vertical: ScrollBar{}
            ScrollIndicator.horizontal: ScrollIndicator { }
            ScrollIndicator.vertical: ScrollIndicator { }

            delegate: CheckBox
            {
                padding: 5
                text: model.number
                checked: model.checked
                onClicked: model.checked = checked
            }
        }

        CheckBox
        {
            text: "Update list"
            checked: updateTimer.running
            onClicked: updateTimer.running = checked
        }
    }

    function randomIndex(max)
    {
      return Math.floor(Math.random() * max);
    }

    Timer {
        id: updateTimer
        interval: 1000;
        running: true;
        repeat: true
        onTriggered:
        {
            var index1 = randomIndex(list.rowCount())
            var index2 = randomIndex(list.rowCount())

            console.log(index1, index2)

            if (index1 !== index2)
            {
                list.move(index1, index2, 1)
            }
        }
    }

    Component.onCompleted:
    {
        for (var i = 0; i < 10; ++i)
        {
            var data = {'number': i, checked: i % 2 === 0};
            list.append(data)
        }
    }
}

But if we change the timer code with the following:

    Timer {
        id: updateTimer
        interval: 100;
        running: true;
        repeat: true
        onTriggered:
        {
            var half = list.rowCount() / 2

            var index1 = half + randomIndex(half)
            var index2 = half + randomIndex(half)

            console.log(index1, index2)

            if (index1 !== index2)
            {
                list.move(index1, index2, 1)
            }
        }
    }

we get an interesting effect: first five CheckBox-es stops responding to the clicks despite the fact that they do not move.
