When i click down-arrow of keyboard then focus get changed and it shows next listview element, but problem here is, initially it is showing 2 Listelement but as i go down so after 2 listelement it's height is getting increased and when i go at last element, it's height comes back to original.

what is the problem here, why the height is changing as i am going from 1 element to last element ???

import QtQuick 2.6
import QtQuick.Window 2.2

Rectangle
{
    id:top
    visible: true
    width: 100
    height: 150

    ListModel
    {
        id:time
        ListElement{time_scale:"30 MIN"}
        ListElement{time_scale:"1 HOUR"}
        ListElement{time_scale:"2 HOUR"}
        ListElement{time_scale:"3 HOUR"}
        ListElement{time_scale:"4 HOUR"}
        ListElement{time_scale:"5 HOUR"}
        ListElement{time_scale:"6 HOUR"}
    }

    Component
    {
        id:comp
        Rectangle
        {
            width: parent.width
            height: 40
            color:"gray"
            border.width: 1
            Text
            {
                text:time_scale
                anchors.verticalCenter: parent.verticalCenter
                anchors.horizontalCenter: parent.horizontalCenter
            }
        }
    }

    Component
    {
        id:high
        Rectangle
        {
            width: parent.width
            height: 40
            color:Qt.rgba(0,0,255,0.1)
            z:5
            /*opacity: 0.5 this will also work */
        }
    }

    Rectangle
    {
        id:master
        width: parent.width
        height: parent.height/2
        anchors.centerIn: parent
        color: "red"

        ListView
        {
            id:ge
            spacing:0
            height: parent.height
            width: parent.width
            model:time
            delegate: comp
            highlight: high
            focus:true
        }
    }

}

@Bhushan_Sure Hello. I don't know your final application, but if you change the height of master component (eliminate the "/2") the problem fix? I test this solution and the change of height was eliminated...

@oria66 if i eliminate master height(/2) , then it will take windows height then in that case it is working fine, But i don't have to give window's height, i want some specific height only. Only i case of parent height it is working fine.

Hi! setting clip property of listview to true would eliminate the visibility of unwanted delegate. But, I'm not sure whether this is the correct solution. Clip operation is a costly operation, would impact the performance.

@Yashpal It work's fine for me, Thank you Yashpal :)
