August 2025 Newsletter

Welcome to the August 2025 edition! This month, KDAB brings you a mix of practical insights, technical guidance, and learning opportunities. Explore how to unify Rust and Qt logging, implement smarter testing strategies for embedded systems, and get started with the new Qt AI Assistant for enhancing productivity in Qt Creator.

KDAB highlights a new addition to Oxidize 2025, where attendees can participate in hands-on workshops and in-depth talks all around Rust. You’ll also find real-world examples from Flutter development with Kalender, a robust Flutter calendar package.

Finally, check out our latest video releases, and lineup of Qt, C++, and Rust training courses by KDAB designed to help you stay ahead with practical, high-quality learning experiences.

Using the Qt Logger in Rust with CXX-Qt

by Joshua Goins

CXX-Qt now unifies Rust and Qt logging by forwarding messages from crates like tracing into the Qt logger. This provides consistent formatting, simpler configuration, and easy redirection of logs, while leveraging Qt’s categories, filters, and tools such as GammaRay. A custom subscriber layer bridges tracing events into Qt, giving developers one streamlined logging system. Read on.

Quality Code Starts with Smarter Testing

by Milian Wolff

Strong testing is essential for reliable, maintainable software—especially in embedded systems. Unit tests, solid coverage, and fast feedback loops keep code dependable. Data-driven testing scales edge cases efficiently, while HAL, HIL, or virtualized hardware help validate hardware-related features. Lightweight crash and in-field reporting complete the picture, ensuring issues are caught and resolved quickly. Read more.

AI Coding with Qt: Qt AI Assistant for Qt Creator

by Jan Marker

Qt AI Assistant integrates AI into Qt Creator, offering code completion, contextual chat, and automated test generation—especially for QML. It supports multiple LLMs, including OpenAI, Anthropic, Google, and Qt’s fine-tuned CodeLlama models. Developers can get explanations, modify code, and quickly bootstrap tests, making AI a practical helper for Qt workflows. More on here.

Countdown for Oxidize 2025

A new workshop at Oxidize 2025, led by Lucas Biaggi (Codethink), focuses on "Making a Rust Project Trustable". This one-day session introduces the Eclipse Trustable Software Framework, guiding participants through practical exercises applying its methodologies to Rust projects, from trustable assertions to continuous verification.

Other workshops include 

• “Rust for Safety Critical Systems” by Jonathan Pallant (Ferrous Systems),
• “Building Embedded GUIs with Rust” by Michael Winkelmann (Slint),
• “Using Rust in an existing C++ application” by Leon Matthes (KDAB), and
• “Why Rust?” by Florian Gilcher (Ferrous Systems).

Ticket sale closes on 7th September. Act fast since workshop seats might sell out before. 

KDAB at Fluttercon 2025

Werner Scholtz (KDAB) presents Kalender, a robust Flutter calendar package, at Fluttercon 2025. The talk covers real-world use cases, the evolution of DateTime extension methods, event storage strategies, interactive layouts with DragTarget and Draggable widgets, and localization. Attendees will gain practical insights into building interactive calendars, handling time zones, and applying iterative development techniques to refine complex Flutter components. More details on here.

KDAB Video Releases This Month
