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.

Finding your way around Qt Creator

The following screenshot shows what you will see when you launch Qt Creator for the first time. Let's take a closer look at each portion of the screen:

The main window, which currently shows the buttons for New Project and Open Project, is your workspace. The workspace also includes links to the Qt projects, examples, and tutorials, as well as Qt's developer documentation, such as its online community and blogs. Under normal conditions, this will be located where you'll see the source code for your application. Along the left-hand side of the screen are a series of icons that let you select various views in your application. They are as follows:

  • The Welcome mode, which shows basic information about Qt Creator
  • The Edit mode, which lets you edit the files that make up your application
  • The Design mode, which lets you use Qt Designer to design the user interface for your application
  • The Debug mode, which lets you debug your application while it's running, including doing things such as viewing the memory and variables, setting breakpoints, and stepping through the application
  • The Projects mode, which lets you adjust the build and link settings for your project
  • The Analyze mode, which lets you profile your application's runtime performance
  • The Help mode, which provides documentation on Qt Creator and the Qt framework

Let's create a new project using C++.
