September 2025 Newsletter | Welcome to the September 2025 edition! This month, KDAB brings you a mix of practical insights, technical guidance, and learning opportunities across desktop, embedded, and AI-assisted development.
Discover strategies for building more robust desktop applications, including techniques to speed up large builds, avoid multithreading issues, and design flexible plug-in architectures. Explore the capabilities of GitHub Copilot’s new Agent mode, which helps coordinate multi-file, cross-language refactoring while highlighting the importance of human oversight in AI-assisted coding.
The in-person training courses are available in Berlin again, after the KDAB office move to a new location has been completed. From Advanced QML and Modern C++ to Rust and embedded-focused sessions, KDAB courses combine theory and hands-on exercises to help developers deepen their skills and apply best practices directly to projects.
Finally, stay up to date with our latest video releases, including the continued Curious Developer AI for coding playlist and the Introduction to Qt Widgets series being added to Qt Academy, and mark your calendars for key events this fall such as Embedded World North America, EuroRust, and Meeting C++ 2025. | | |

by Jan Marker | AI-assisted coding is moving beyond single-file suggestions, and Jan Marker’s new blog highlights how GitHub Copilot’s Agent mode supports cross-language refactoring in C++/QML projects. By analyzing the entire repository, Agent mode can coordinate changes across data structures, models, and UI files, while giving developers clear diffs to review. Jan notes that while this speeds up repetitive edits, careful human oversight is still essential to preserve correctness and code quality. More on here. |

KDAB Training Courses back in Berlin | KDAB’s scheduled training courses are once again being held at our Berlin office, now relocated to a new space. After a temporary move to our UK facility in Macclesfield, in-person sessions are back in Berlin, providing a central hub for developers to join our expert-led courses.
The KDAB training portfolio covers a wide range of topics, including C++, Qt, QML, debugging, performance optimization, and more. Each course combines best practices with practical exercises to help developers apply new skills directly to their projects. You can explore the complete training portfolio or check the schedule of upcoming sessions. |

Qt Academy: Introduction to Qt Widgets, Part 8 |
|
|
|---|
|
Part 8 of our Introduction to Qt Widgets series is now live on Qt Academy. This module focuses on the Model/View architecture, showing how to work with lists, tables, and trees. Through examples and live coding, you’ll learn the differences between Widget and View classes, how to manage user interaction, and how to implement models such as ListModel, TableModel, and TreeModel. Start this course or check out the other courses on here. |
