Begin writing graphical user interface(GUI) applications for building human machine interfaces with a clear understanding of key concepts of the Qt framework
- Learn how to write, assemble, and build Qt application from the command line
- Understand key concepts like Signals and Slots in Qt
- Best practices and effective techniques for designing graphical user interfaces using Qt 5
Qt is a cross-platform application framework and widget toolkit that is used to create GUI applications that can run on different hardware and operating systems. The main aim of this book is to introduce Qt to the reader. Through the use of simple examples, we will walk you through building blocks without focusing too much on theory.
Qt is a popular tool that can be used for building a variety of applications, such as web browsers, media players such as VLC, and Adobe Photoshop. Following Qt installation and setup, the book dives straight into helping you create your first application.
You will be introduced to Widgets, Qt’s interface building block, and the many varieties that are available for creating GUIs. Next, Qt’s core concept of signals and slots are well illustrated with sufficient examples. The book further teaches you how to create custom widgets, signals and slots, and how to communicate useful information via dialog boxes. To cap everything off, you will be taken through writing applications that can connect to databases in order to persist data.
By the end of the book, you should be well equipped to start creating your own Qt applications and confident enough to pick up more advanced Qt techniques and materials to hone your skills.
What you will learn
- Set up and configure your machine to begin developing Qt applications
- Discover different widgets and layouts for constructing UIs
- Understand the key concept of signals and slots
- Understand how signals and slots help animate a GUI
- Explore how to create customized widgets along with signals and slots
- Understand how to subclass and create a custom windows application
