Cross-Platform Development with Qt 6 and Modern C++

By: Nibedit Dey

Overview of this book

Qt is a cross-platform application development framework widely used for developing applications that can run on a wide range of hardware platforms with little to no change in the underlying codebase. If you have basic knowledge of C++ and want to build desktop or mobile applications with a modern graphical user interface (GUI), Qt is the right choice for you. Cross-Platform Development with Qt 6 and Modern C++ helps you understand why Qt is one of the favorite GUI frameworks adopted by industries worldwide, covering the essentials of programming GUI apps across a multitude of platforms using the standard C++17 and Qt 6 features. Starting with the fundamentals of the Qt framework, including the features offered by Qt Creator, this practical guide will show you how to create classic user interfaces using Qt Widgets and touch-friendly user interfaces using Qt Quick. As you advance, you'll explore the Qt Creator IDE for developing applications for multiple desktops as well as for embedded and mobile platforms. You will also learn advanced concepts about signals and slots. Finally, the book takes you through debugging and testing your app with Qt Creator IDE. By the end of this book, you'll be able to build cross-platform applications with a modern GUI along with the speed and power of native apps.

Chapter 7: Model View Programming

Model/View programming is used to separate data from Views in Qt to handle datasets. The Model/View (M/V) architecture differentiates the functionalities that give freedom to the developers to modify and present the information on the User Interface (UI) in multiple ways. We will discuss each component of the architecture,the related convenience classes offered by Qt, and how to use them with practical examples. Throughout this chapter, we will be discussing the Model View pattern and understand the underlying core concepts.

In this chapter, we will discuss the following topics:

  • Fundamentals of the M/V architecture
  • Using Models and Views
  • Creating custom Models and delegates
  • Displaying information using M/V in Qt Widgets
  • Displaying information using M/V in QML
  • Using C++ Models with QML

By the end of this chapter, you will be able to create a data model and display information on a customized UI. You will be able...
