Application Development with Qt Creator - Third Edition

By: Lee Zhi Eng, Ray Rischpater

Overview of this book

Qt is a powerful development framework that serves as a complete toolset for building cross-platform applications, helping you reduce development time and improve productivity. Completely revised and updated to cover C++17 and the latest developments in Qt 5.12, this comprehensive guide is the third edition of Application Development with Qt Creator. You'll start by designing a user interface using Qt Designer and learn how to instantiate custom messages, forms, and dialogues. You'll then understand Qt's support for multithreading, a key tool for making applications responsive, and the use of Qt's Model-View-Controller (MVC) to display data and content. As you advance, you'll learn to draw images on screen using Graphics View Framework and create custom widgets that interoperate with Qt Widgets. This Qt programming book takes you through Qt Creator's latest features, such as Qt Quick Controls 2, enhanced CMake support, a new graphical editor for SCXML, and a model editor. You'll even work with multimedia and sensors using Qt Quick, and finally develop applications for mobile, IoT, and embedded devices using Qt Creator. By the end of this Qt book, you'll be able to create your own cross-platform applications from scratch using Qt Creator and the C++ programming language.

Using the model editor

The model editor is a new addition to Qt's toolset. You can use it to create Universal Modeling Language (UML)-style models to visualize how your application would behave. This is one of the good ways to communicate with your programmers or to present your idea to your team. Currently, the model editor is still in the beta testing phase and will be subject to changes in later versions. At the moment, you need to enable it in Qt Creator before you're able to use it. To do this, try the following steps:

  1. Go to Help | About Plugins to open up the Installed Plugins window. Make sure that the ModelEditor option has been checked.
  1. After that, you can create a new model file by going to File| New File or Project and select either the Model or Scratch Model options under Files and Classes | Modeling. The other option, State Chart, is for state machine...
