Is it possible to make a cycle swipe items in qml?

问题

I use swipeview in qml. I can swipe items from first to final and back. Is it possible to swipe from final to first immediatly ? I didn't find any information in docs.

You can do that with PathView. Qt Quick Controls 2's Tumbler can also be made to wrap because it uses PathView internally.

You can use PathView. Some codes like this:

import QtQuick 2.0

Rectangle {
    width: 200
    height: 200

    ListModel {
        id: model
        ListElement {
            color: "red"
        }
        ListElement {
            color: "green"
        }
        ListElement {
            color: "blue"
        }
    }

    Component {
        id: delegate
        Rectangle {
            id: wrapper
            width: view.width
            height: view.height
            color: model.color

            Text {
                anchors.centerIn: parent
                font.pointSize: 26
                font.bold: true
                color: "white"
                text: index
            }
        }
    }

    PathView {
        id: view
        anchors.fill: parent
        snapMode: PathView.SnapOneItem
        highlightRangeMode: PathView.StrictlyEnforceRange
        currentIndex: -1
        model: model
        delegate: delegate
        path: Path {
            startX: -view.width / 2  // let the first item in left
            startY: view.height / 2  // item's vertical center is the same as line's

            PathLine {
                relativeX: view.width * view.model.count  // all items in lines
                relativeY: 0
            }
        }
    }
}
