Listview scroll one item/element at a time

[nikhil30]

Hello Qt devs!

I have a ListView in qml which contains several rows (holding simple information to the user). I am implementing two buttons, which I would like to have the same functionality as the arrow buttons in the scrollbar.
On clicking up arrow button, last/previous element in list should be displayed, similarly, on clicking down arrow button , next element in list should be displayed
Can this be done?

Thank you for your time!

Is this what you are looking for.

import QtQuick 2.15
import QtQuick.Controls 2.15

ApplicationWindow {
    width: 640
    height: 480
    visible: true
    title: qsTr("Scroll")

    ScrollView {
        anchors.fill: parent

        ListView {
            id: listView
            width: parent.width
            model: 20
            delegate: ItemDelegate {
                text: "Item " + (index + 1)
                width: listView.width
                onClicked: listView.currentIndex = index
            }
            currentIndex: 0
            highlight: Rectangle {
                width: listView.width
                height: 40
                color: "transparent"
                border.color: "red"
            }
            snapMode: ListView.SnapToItem
            footerPositioning: ListView.OverlayFooter
            footer: Row {
                z: 2
                Button {
                    text: "prev"
                    onClicked: listView.currentIndex = listView.currentIndex - 1
                }
                Button {
                    text: "next"
                    onClicked: listView.currentIndex = listView.currentIndex + 1
                }
            }
        }
    }
}

Also, have a look at how positionViewAtIndex works. It helps to position the view to the specified index

@Mammamia
i am using Qt 5.6.3 and also not using itemDelegate as delegate.
So how to identify the currentIndex position of list view which is displayed...?
After clicking up/down buttons, i may need to detect the currentItem index of list.
