Learn Qt 5

By: Nicholas Sherriff

Overview of this book

Qt is a mature and powerful framework for delivering sophisticated applications across a multitude of platforms. It has a rich history in the Linux world, is widely used in embedded devices, and has made great strides in the Mobile arena over the past few years. However, in the Microsoft Windows and Apple Mac OS X worlds, the dominance of C#/.NET and Objective-C/Cocoa means that Qt is often overlooked. This book demonstrates the power and flexibility of the Qt framework for desktop application development and shows how you can write your application once and deploy it to multiple operating systems. Build a complete real-world line of business (LOB) solution from scratch, with distinct C++ library, QML user interface, and QtTest-driven unit-test projects. This is a suite of essential techniques that cover the core requirements for most LOB applications and will empower you to progress from a blank page to shipped application.

Web Requests

This chapter takes us worldwide as we venture even further out from our application to the internet. Beginning with writing some helper classes to manage web requests for us, we will pull data from a live RSS feed and interpret it via some XML processing. With the parsed data at hand, we can then put our QML skills to use and display the items on a new view. Clicking on one of the RSS items will launch a web browser window in order to view the related article in more detail. We will cover the following topics:

  • Network access
  • Web Requests
  • RSS View
  • RSS
