Swiping through full resolution images

The last page we have to implement in gallery-mobile is the full resolution image page. In Chapter 4, Conquering the Desktop UI, we navigated through the images using previous/next buttons. In this chapter, we target the mobile platform. Therefore, navigation should be effected using a touch-based gesture: a fling.

Here is the implementation of this new PicturePage.qml file:

import QtQuick 2.0 
import QtQuick.Layouts 1.3 
import QtQuick.Controls 2.0 
import "." 
 
PageTheme { 
 
    property string pictureName 
    property int pictureIndex 
 
    toolbarTitle: pictureName 
 
    ListView { 
        id: pictureListView 
        model: pictureModel 
        anchors.fill: parent 
        spacing: 5 
        orientation: Qt.Horizontal 
        snapMode: ListView.SnapOneItem 
        currentIndex: pictureIndex 
 
        Component.onCompleted...
