Overview of this book

Qt 5.7 is an application development framework that provides a great user experience and develops full-capability applications with Qt Widgets, QML, and even Qt 3D. This book will address challenges in successfully developing cross-platform applications with the Qt framework. Cross-platform development needs a well-organized project. Using this book, you will have a better understanding of the Qt framework and the tools to resolve serious issues such as linking, debugging, and multithreading. Your journey will start with the new Qt 5 features. Then you will explore different platforms and learn to tame them. Every chapter along the way is a logical step that you must take to master Qt. The journey will end in an application that has been tested and is ready to be shipped.

Preface

Displaying albums with ListView


Let's make our first page for this mobile application! Create a file in gallery.qrc called AlbumListPage.qml. Here is the page header implementation:

import QtQuick 2.0 
import QtQuick.Layouts 1.3 
 
import QtQuick.Controls 2.0 
 
Page { 
 
    header: ToolBar { 
        Label { 
            Layout.fillWidth: true 
            text: "Albums" 
            font.pointSize: 30 
        } 
    } 
... 
} 

A Page is a container control with a header and footer. In this application, we will only use the header item. We assign a ToolBar to the header property. The height of this toolbar will be handled by Qt and will be adjusted depending on the target platform. In this first simple implementation, we only put a Label displaying the text "Albums".

Add a ListView element to this page after the header initialization:

ListView { 
    id: albumList 
    model: albumModel 
    spacing: 5 
    anchors.fill: parent 
 
    delegate: Rectangle { 
        width: parent.width 
...
