This is a course for learning the Qt Framework. It was commissioned by Felgo, an official Qt Technology Partner.


Learn the basic concepts, tools, and functions that you need to build fully functional cross platform apps using Qt, QML and Felgo.

Felgo is an extension for Qt that allows you to build fully functional cross platform applications on Android, iOS, Windows, Mac Linux and Embedded Linux using a single code base, with increased efficiency than the plain Qt framework.

This course will show you how to create ‘Property Cross’, an application that taps into an API on the web to download available real estates to buy nearby.

Via this one app, you will learn everything you need to know about creating apps. User interfaces, web API calls, programmatic events and more!

Build a Strong Foundation in QML and Qt with this Course for Beginners

  • Learn how to use QML to create desktop and mobile apps in ultra fast time

  • Understand how to structure a Qt application correctly

  • Learn the Qt Framework

  • Discover how to make asynchronous requests to a server without slowing down your app

  • Display asynchronously downloaded images in a single line of code

  • Create infinite scrolling lists of real estates

  • Save favourite real estates

  • Learn about app navigation basics

  • Create fully functional apps using 10 times less code than other frameworks!

  • And so much more!

A Rapid Prototyping Technology Awaits

Learning the fundamentals of Felgo places a powerful and useful tool at your fingertips. It comes with many tools and features that native mobile developers don’t have immediate access to, including the ability to download asynchronous images without plugins!

In fact, Qt and QML are used by over a million developers worldwide. Chances are extremely high that you've used software built in Qt. VLC is but one of the well known examples.

Content and Overview

This course is suitable for beginner to intermediate programmers (although you should have some experience in any programming language prior to starting).

Throughout our time together we’ll create ‘Property Cross’, a fully fledged property search app that shows you real estates at a chosen location. What’s more it also allows you to browse based on location of your device as well as saving your favourite real estates!

Along the way you’ll learn most of the Qt and QML fundamentals that you need in order to become a fully fledged cross platform developer.

How You’ll Proceed

Starting with the installation of Felgo (and the free Qt Creator IDE), this course will take you through creating fluid interfaces using the powerful yet simple QML language.

After mastering the basics you’ll learn how to do essentials such as listening to events and responding to button clicks.

Following that we’ll deep dive into how you should correctly structure an application in terms of fetching internet data and relaying signals to the main view. This knowledge will benefit you immensely as it is useful across all software development frameworks - not just Qt and QML.

You’ll also learn another fundamental - an infinite scrolling list of data. You’ll learn how to show rows of images, text and more as well as allowing users to click through to a new page and see the details of a chosen property.

During this journey you’ll gain a thorough understanding of how mobile apps are constructed - an extremely useful skill that can be transposed to any other development framework, in any other programming language.

On completion you’ll be able to create your own fully fledged cross platform apps ready to publish on any popular platform!

I look forward to working with you!

Who this course is for:
  • Developers new to the Qt Framework
  • Developers looking to create cross platform apps in a single codebase
  • Beginners to development with only a few months experience
