Overview of this book

Qt 5.11 is an app development framework that provides a great user experience and develops full capability applications with Qt Widgets, QML, and even Qt 3D. Whether you're building GUI prototypes or fully-fledged cross-platform GUI applications with a native look and feel, Mastering Qt 5 is your fastest, easiest, and most powerful solution. This book addresses various challenges and teaches you to successfully develop cross-platform applications using the Qt framework, with the help of well-organized projects. Working through this book, you will gain a better understanding of the Qt framework, as well as the tools required to resolve serious issues, such as linking, debugging, and multithreading. You'll start off your journey by discovering the new Qt 5.11 features, soon followed by exploring different platforms and learning to tame them. In addition to this, you'll interact with a gamepad using Qt Gamepad. Each chapter is a logical step for you to complete in order to master Qt. By the end of this book, you'll have created an application that has been tested and is ready to be shipped.

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
