In CXX-Qt 0.8.0, Rust applications now have a way to forward structured log events from the tracing crate to the Qt logging system. This enables unified logging output across Rust and Qt, enabling consistent formatting, better filtering, and easier integration with tools like GammaRay. By leveraging qt_message_output and QMessageLogContext, developers can bridge Rust's log metadata with Qt's categorized logging infrastructure.
In this video, Florian (CEO, Ferrous Systems) and Till Adam (CFO, KDAB) explore how integrating Rust with existing C++ projects can be a powerful approach, and share helpful resources for those looking to get started.
Oxidize - The Applied Rust conference held in Berlin, Germany in September 2025, offered a unique opportunity for immersion in the cutting edge of Rust programming, connecting with a vibrant community of developers and experts. Participants were able to gain invaluable insights into real-world applications of Rust, through engaging talks and hands-on workshops. This video promoted the event.
Excerpted from an interview with Volker Hilsheimer and Maurice Kalinowski of the Qt Company at Qt World Summit, 2025.
At Qt World Summit 2025, Jesper met with Volker Hilsheimer (Chief Maintainer of the Qt Project) and Maurice Kalinowski (Product Director at The Qt Group) for a talk about what's new in Qt and what direction it is taking.
Are you curious about the transition from a C++ code base to Rust? This video explores the experiences of the @hulks_tuhh, a RoboCup team from Hamburg, that successfully made the switch. Discover their initial motivations for using Rust, the valuable lessons learned throughout the process, and how the team is currently benefitting from it. Listen to their story and learn why KDAB became one of their sponsors.
Not sure which technology stack and UI library to choose for your next embedded project? Olivier Goffart from Slint and Miłosz Kosobucki from KDAB discuss why C++ and Slint may be a good choice. Learn about the pros and cons of these technologies to make a more informed decision.
Choosing the right programming language for your embedded Linux device is crucial. Learn the nuances of C++, Rust, and Dart to make an informed decision.
In a recent email, KDABian Leon Matthes highlighted some of his go-to command line tools for everyday use on Unix. His recommendations sparked a lively exchange among our colleagues, each sharing their own favorite utilities. Many of these tools offer efficient alternatives to standard Unix programs, speeding up the workflow or otherwise enriching the development […]
CXX-Qt is KDAB's extension to CXX, which adds Qt features like properties, signals and slots to CXX. In this step-by-step tutorial, we implement a QAbstractItemModel subclass, which is key to exposing structured data to QML.
CXX-Qt is KDAB's extension to CXX, which adds Qt features like properties, signals and slots to CXX. In this step-by-step tutorial, we extend our "Hello World!" application from the last video with a very basic Qt GUI.
CXX is an opinionated library that allows mixing C++ and Rust in a safe and idiomatic way. In this step-by-step tutorial, we implement an example application that uses CXX to bridge between C++ and Rust. In the following videos, we will expand on this knowledge to add Qt to the mix with CXX-Qt.
In the last months, governments around the world have put a focus on memory safe programming languages. For C++ projects, Rust has often been suggested as the natural choice to port to.
We just released CXX-Qt version 0.7! CXX-Qt is a set of Rust crates for creating bidirectional Rust ⇄ C++ bindings with Qt. It supports integrating Rust into C++ applications using CMake or building Rust applications with Cargo. CXX-Qt provides tools for implementing QObject subclasses in Rust that can be used from C++, QML, and JavaScript. […]
In our earlier blog, The Smarter Way to Rust, we discuss why a blend of C++ and Rust is sometimes the best solution to building robust applications. But when you’re merging these two languages, it’s critical to keep in mind that the transition from C++ to Rust isn’t about syntax, it’s about philosophy. Adapting to […]
If you’ve been following our blog, you’re likely aware of Rust’s growing presence in embedded systems. While Rust excels in safety-by-design, it’s also common to find it integrated with C++. This strategic approach leverages the strengths of both languages, including extensive C++ capabilities honed over the years in complex embedded systems. Let’s delve into some […]
In the two previous posts (Part 1 and Part 2), we looked at how to build bindings between C++ and Rust from scratch. However, while building a binding generator from scratch is fun, it's not necessarily an efficient way to integrate Rust into your C++ project. Let's look at some existing technologies for mixing C++ […]
Simon Hausmann from Slint talks about how KDAB and tQCS revamped the user interface of SK Signet's top electric vehicle charger. This app plays video ads while the car charges. Video playback is handled by FFmpeg, and networking is managed with Curl. The product comes in 15-inch and 32-inch screen options with dynamic dark/light mode.
You may have already faced the challenge of showing website content within your Qt application. However, Qt doesn't excel in this - it's often slow and securely connecting to external web sources is also a valid concern. Watch this video to discover how seamlessly integrating Rust into your Qt application logic can address these issues and enhance performance.
With the Qt WebEngine module, Qt makes it possible to embed a webview component inside an otherwise native application. Under the hood, Qt WebEngine uses the Chromium browser engine, currently the de facto standard engine for such use cases. While the task of writing a brand new standard-compliant browser engine is infamous as being almost […]
