April 2026

The April 2026 edition brings a fresh mix of practical content across Qt, Slint, and the broader C++ and Rust ecosystem.

Qt 6.11 is out, and Jesper Pedersen sits down with the Qt Group to tour its highlights, including QCanvasPainter, QRangeModelAdapter, and the new TaskTree. On the Slint side, explore how to build reusable Slint UI libraries with Rust crates, now made possible by the new experimental module build feature in Slint 1.14. 

New video episodes also continue the CLion series, covering Qt Designer integration and managing multiple Qt versions with toolchains and CMake profiles.

On the training front, a new Advanced Qt Widgets course has been added for October, with several other sessions confirmed across Qt, C++, and Rust. As always, upcoming events - including RustWeek, Oxidize, and Qt World Summit - are listed to help you plan ahead.

Building Reusable Slint UI Libraries 

with Rust Crates

There is a new experimental module build feature since Slint 1.14, which for the first time allows components defined in .slint files to be exported from a Rust crate and imported into other applications via import { Foo } from "@MyLibrary" - opening the door to shareable, reusable Slint UI libraries on crates.io. Read on.

Qt 6.11 Released

What's cooking?

To celebrate the release of Qt 6.11, Jesper Pedersen sat down once again with Maycon Stamboroski from the Qt Group to explore what's new in the latest version. 

One of the highlights is QCanvasPainter, which makes custom drawing in Qt Quick significantly easier and faster. The conversation also covers QRangeModelAdapter, a welcome addition that simplifies access to underlying data when working with QRangeModel. Finally, Jesper and Maycon dive into the brand-new TaskTree - discussing what it is, how it's intended to be used, and how developers can get started with it today. 

If you want a guided tour of Qt 6.11's most exciting new features straight from the source, this is the episode to watch.

KDAB Training

New Addition to Training Schedule

A new Advanced Qt Widgets training has been added to the KDAB schedule, planned for 13–15 October 2026. Aimed at developers already familiar with Qt Widgets, this hands-on KDAB course deepens your understanding of Qt internals and advanced techniques, with optional topics including multithreading and inter-process communication. Register here.

With over 20 years of experience, KDAB offers hands-on training in Qt/QML, Modern C++, 3D/OpenGL, Debugging & Profiling, and Rust - for all skill levels. Courses are available as scheduled group sessions or in-company training for teams, with some online options. Explore the full training portfolio.

'Qt Widgets and more' - Interview

Static Functions Instead of Private Methods in C++

Is it a good idea to put helper functions into C++ files rather than having them as private member functions?
Watch Jesper interview Giuseppe D'Angelo (KDAB) to learn more. Among other things, he will argue why you should even have anonymous namespace and static keyword for such functions

Watch all the 'Qt Widgets and more' episodes here.

New Episodes - Qt with CLion

CLion's Qt Designer integration may lack Qt Creator's polish, but Jesper Pedersen shows how to configure an External Tool to open the matching .ui file from your current .cpp via Shift+F4 - plus re-binding "Open tab in new window" to Ctrl+E,4 to better mimic Qt Creator's window handling. Watch this episode.

If Qt Creator's kits feel more intuitive than CLion's toolchains and CMake profiles, Jesper Pedersen has you covered. He explains how CLion discovers Qt via qmake in your PATH, how to define toolchains using per-version environment setup files, and how to wire them into named CMake profiles like "Debug-6.9" and "Release-6.10".

CLion comes with its own code formatter: Should you use that or clang-format? And if you chose clang-format, how do you set that up?

Watch this episode to learn more.
