In the beginning, there was C. That sentence actually could serve as the introduction to a multitude of blog posts, all of which would come to the conclusion “legacy programming conventions are terrible, but realistically we can’t throw everything out and start over from scratch”. However, today we will merely be looking at two ways […]

KDSoap 2.2.0 Released
We’re pleased to announce the release of KDSoap version 2.2.0, an update that brings new enhancements to improve both the general build system and client-side functionality. What is KDSoap? KDSoap, a SOAP (“Simple Object Access Protocol“) component rooted in Qt, serves as an essential tool for both client-side and server-side operations. Tailored for C++ programmers […]
Projection Matrices with Vulkan – Part 2 Deriving a perspective projection matrix for Vulkan
Showing how to derive the projection matrix, this second part of the series teaches how to create perspective projection matrices for Vulkan and adapt them to your needs.
Mixing C++ and Rust for Fun and Profit: Part 1 Or why switching to Rust is such a large undertaking
For quite some time, I have been bothered by this thought: Individual programming languages (C++, Rust, Go, etc.) are traditionally viewed as walled gardens. If your main() function is written in C++, you had better find yourself C++ libraries like Qt to build the rest of your codebase with. Do you want to use Flutter […]
CXX-Qt 0.6 Release
We just released CXX-Qt version 0.6! CXX-Qt is a set of Rust crates for creating bidirectional Rust ⇄ C++ bindings with Qt. It can be used to integrate Rust into C++ applications using CMake or build Rust applications with Cargo. CXX-Qt provides tools for implementing QObject subclasses in Rust that can be used from C++, […]
Supercharging VS Code with C++ Extensions
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++ […]
Qt for VS Code, the TL;DR version Using VS Code IDE to work on Qt project
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 […]
PSA: QPointer has a terrible name
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 […]
Optimizing and Sharing Shader Structures
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 […]
KDGpu v.0.1.0 is released a Vulkan wrapper to make modern graphics easier
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 […]
