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.

Displaying the selected album with AlbumWidget

This widget will display the data of the selected album from AlbumListWidget. Some buttons will allow us to interact with this album.

Try now to create the layout of the AlbumWidget.ui file. Here is the final result:

The top frame, albumInfoFrame, with a horizontal layout contains:

  • albumName: displays the album's name (Lorem ipsum in the designer).
  • addPicturesButton: allows the user to add picture files.
  • editButton: used to rename the album.
  • deleteButton: Used to delete the album.

The bottom element, thumbnailListView, is a QListView. This list view represents items from PictureModel. By default, QListView is able to display a picture next to a text requesting Qt::DisplayRole and Qt::DecorationRole from the model.

Take a look at the AlbumWidget.h header file:

#include <QWidget> 
#include <QModelIndex>
