The Need for Simple & Modular QR Generation in QML Recently, our designer Nuno Pinheiro needed to generate QR codes for an Android app in QML and started asking around about a simple way to do this. The best existing QML solution was QZXing, a Qt/QML wrapper for the 1D/2D barcode image processing library ZXing. […]

Optimizing Embedded Product Design The Case for Off-the-shelf Boards
Choosing the right system-on-chip (SoC) is probably your first consideration when designing an embedded product, followed closely by deciding whether to use an off-the-shelf board or design your own. The case for commercial boards in initial designs For the first product in a new line, consider using a commercially available board that features your chosen […]
The Embedded Developer’s Dilemma in Choosing Hardware
When designing an embedded product, there’s a lot riding on those crucial first decisions of choosing a hardware vendor and board. Clearly, the hardware you select must be powerful enough to support your product, a challenging determination given that software is usually still in the planning stages at this point in the process. Plus, planning […]
Mixing C++ and Rust for Fun and Profit: Part 2 Of structs and strings
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 […]
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.
Introducing KDDockWidgets 2.0 A Leap Forward in Flexibility and Integration
We’re happy to announce KDDockWidgets version 2.0, a major milestone that brings many improvements and architectural enhancements to our powerful docking library. KDDockWidgets is a versatile framework for custom-tailored docking systems in Qt written by KDAB’s Sérgio Martins. For more information about its rich set of features, take a gander at its GitHub repository. What […]
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++, […]
Projection Matrices with Vulkan – Part 1 How transformations differ from OpenGL to Vulkan
This post explains the difference between OpenGL and Vulkan transformations and how to adapt code to get the desired results, plus actually understanding what's going on.
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++ […]
