In a previous blog we demonstrated the most straightforward method to optimize Visual Studio Code for a Qt / C++ environment: simply let the tools do all the work! The example GitHub project we discussed automatically installs both the Microsoft C/C++ and clangd extensions into VS Code. You might wonder why you need both C++ […]

Our colleague Alessandro Ambrosano created a series of blogs (parts 1, 2, and 3) that explain how to get Visual Studio Code configured for Qt development. In that series, Alessandro covers all the details you need to get your VS Code environment configured exactly the way you want it. But there’s a lot there to […]

KDAB is proud to be a Silver Sponsor at this year's Meeting C++, a highly recommended 3-day hybrid event for the European C++ community, offering 44 Talks in 4 tracks, November 12th - 14th. While this is also an in-person event, there is a substantial concurrent online program, so that high-class international speakers can easily […]

Today's blog post is about a small utility class in Qt with a... questionable name: QPointer. If you're new to Qt, maybe don't check out QPointer's documentation just yet, and try to guess what the class does based on its name alone. I've seen countless users being very confused by it. Some end up using […]

I'm happy to announce the immediate availability of Heaptrack v1.5.0. Heaptrack is a heap memory profiler targeting mainly Linux, as well as FreeBSD. To learn more, please visit the project website. Version 1.5.0 incorporates about 70 changes since the v1.4.0 release from June last year. The highlights include: - Elfutils is now used for symbolizing […]

KDAB has released GammaRay 3.0.0. GammaRay is a software introspection tool for Qt applications developed by KDAB for internal use, and now shared with the developer community on GitHub. This release is a special one, as we have now added Qt 6 support. An overview of changes since the last release Things we have added […]

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? In this article I'm providing a crash course on what GitHub Actions are and how to use it for […]

KDAB was Platinum sponsor at this year's Qt World Summit on November 28th-29th Finally, the Qt World Summit was back in person at the bcc (the Berlin Congress Centre)! Those of you who have been attending former years know that KDAB usually offers a KDAB Training Day as part of the conference. This year, we […]

CppCon is the annual, week-long face-to-face gathering for the entire C++ community – the biggest C++ event in the world. This year, CppCon takes place in Aurora, Colorado, near the Denver airport, and including multiple diverse tracks, the conference will appeal to anyone from C++ novices to experts. At CppCon, you can expect lots of […]

The time has come, fellow devs. We are on our way to uncover the newest concept of C++ language - Coroutines. They are already used by several programming languages, like C# async tasks and yield iterables, forming LINQ base; JS with awaitables, replacing the old way of making consecutive calls, that was hard to understand […]

The SPS (Smart Production Solutions) event is the industry highlight of the automation sector. With its unique concept, it represents the complete spectrum of smart and digital automation - from simple sensors to intelligent solutions, from what is feasible today to the vision of a comprehensively digitized industrial world. We will be there showing how […]

The Engineering Design Show (EDS) returns to The Coventry Building Society Arena (UK) on the 11th - 12th of October 2023. EDS has been showcasing mechanical, electronics, and embedded design for over a decade. It's a great show to visit for design engineers who are looking for direct access to the latest products, services and […]

When writing large graphics applications in Vulkan or OpenGL, there's many data structures that need to be passed from the CPU to the GPU and vice versa. There are subtle differences in alignment, padding and so on between C++ and GLSL to keep track of as well. I'm going to cover a tool I wrote […]

We're pleased to announce we've added a new library, KDGpu, to the arsenal of tools we invent to make our lives easier - and then share with you on KDAB's GitHub. Who is this for? If you want to become more productive with Vulkan or learn the concepts of modern explicit graphics APIs, then KDGpu […]

Reverse engineering in general is a tricky business and sometimes not very orthodox. So, why bother to write this article? Well, sometimes reverse engineering is also for something good. It started when my wife dusted off her watch. We had a huge unpleasant surprise when we found that the companion app is not available anymore […]

Last time we touched upon object lifetime and today we wrap up the basics with a bit of a spicy topic of object ownership. We covered the lifetime quirks, and we found out that manual memory management can be a nightmare, even if we new and delete in the correct order. There must be something […]

The KDAB Training Day will be back in Berlin, at the H4 Hotel Berlin Alexanderplatz, on November 27th this year, right before the annual Qt World Summit, which will happen November 28-29th. Ideal to take part in both events! KDAB is well-known for its quality training courses around Qt/QML, Modern C++, Debugging and Profiling, OpenGL, […]

An important part of working with Vulkan and other modern explicit rendering APIs is the synchronization of GPU/GPU and CPU/GPU workloads. In this article we will learn about what Vulkan needs us to synchronize and how to achieve it. We will talk about two high-level parts of the synchronization domain that we, as application and […]

Last time we discussed Value Semantics. However, I missed one topic that is super important for a better understanding of basic building blocks of C++. Today, we are going to talk about an object. Without further ado, let’s dive deeper! Object What is an object? According to the C++ standard, part 3.9.8 under the name […]

C++ is an old language. Many aspects of our programming styles have become habits that we do not think about too much today. In this blog, I’m going to address one major issue that has resulted from such habits and get you prepared for a new bright world of C++2b. So without further ado, let’s […]
