Welcome to our September Newsletter

We bring you Intro to C++ Coroutines: Concept followed by GitHub Actions for C++ and Qt, then the Release of GammaRay 3.0.0.

We also have a new video in our Qt Widgets and More series, the complete tutorials on GammaRay for Qt Widgets Applications, a word or two on Training, and Events – including KDAB at the Engineering Design Show coming up Oct 11th-12th and a focus on a November Week in Berlin with Qt you’ll want to get ready for.

Finally, some off-topic news we just couldn’t resist sharing with you: Raspberry Pi 5 is ready for pre-order now! Check it out.

Intro to C++ Coroutines: Concept

by Ilya Doroshenko

It seems the C++ committee followed the quote: “Give a man a fish and you feed him for a day; teach a man to fish and you feed him for a lifetime”.

In this blog, Ilya introduces coroutines in all their complexity and what you need to understand before making your own coroutine.

GitHub Actions for C++ and Qt

How to use GitHub Actions for C++ and Qt projects

by Milosz Kosobucki.

You may already be hosting your code on GitHub, but do you know that GitHub provides a built-in Continuous Integration solution called GitHub Actions that is very easy to set up and free for public repositories?

Milosz offers a crash course on what GitHub Actions are and how to use it for your C++ and Qt projects.

KDAB Training

You thought Jesper was ‘just’ that guy from the Qt Widgets and More series, didn’t you? In fact there’s a whole lot more to Jesper, who’s been with KDAB since the beginning and is the guiding light behind our world-class training, having himself authored most of the Qt course material.

Let Jesper tell you why KDAB training is so successful in this 5 minute video.

Anyone who’s interested in contributing – from development to community work – is very welcome. Check out the practical info and register.

Venue: Estrel Hotel Berlin.
