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.

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.
