KDAB has released KDDockWidgets 1.2.0. In this version we added support for two platforms, Wayland and WASM. Additionally, Qt 6.0 is now supported. Update: We now have a WASM Demo which you can run directly on your browser. It’s very similar to what you’d get on the desktop, except for the docking indicators and performance (depending on […]

Qt Desktop Days – Day 4
Wait, there’s more? Yes, indeed. Qt Desktop Days delivered a lot of great content we’ve just got to share. VLC and Qt, a history If you need to play the widest variety of audio, video, or streaming formats on the planet, you probably know about VLC (the “cone player”). But did you know that VLC […]
The Eight Rules of Multithreaded Qt The biggest dos and don'ts for multi-threading in Qt
While the concept of multithreading may be straightforward, code with threads is responsible for some wicked bugs, which can be nearly impossible to reproduce or track down. This makes writing bullet-proof code using threads a tall order. Let’s look a little deeper into why that is. First, you need better than average knowledge about the […]
NEW: Qt / QML introduction tutorial release
Today, we see more and more self-guided and remote learning via videos online. To that end, we have been working for more than 6 months now to capture our regular Qt/QML Introduction training on video.
Qt 3D: One too many threads or what has changed in 5.14
Qt 3D makes heavy use of threads, as a way to spread work across CPU cores and maximize throughput, but also to minimize the chances of blocking the main thread. Though nice on paper, the last case eventually leads to added complexity. Sometimes, there are just one too many threads. In the past, we’ve been […]
KDTableToListProxyModel: a flattening proxy model
With this blog post we are going to kickstart our brand new blog series about KDToolBox. The first class we’re exploring is KDTableToListProxyModel, a table-to-list proxy model. The main use case for KDTableToListProxyModel is exposing tabular models to Qt Quick. Qt Quick has a certain number of “view” elements that only support list models: for […]
Python binding for Kuesa Load, render and manipulate glTF models in your python application using Qt 3D
KUESA™ is a Qt module designed to load, render and manipulate glTF 2.0 models in applications using Qt 3D. Kuesa provides a C++ and a QML API which makes it easy to do things like triggering animations contained in the glTF files, finding camera details defined by the designer, etc. It is a great tool so […]
New in Qt 5.11: improvements to the model/view APIs (part 1)
The Qt model/view APIs are used throughout Qt — in Qt Widgets, in Qt Quick, as well as in other non-GUI code. As I tell my students when I deliver Qt trainings: mastering the usage of model/view classes and functions is mandatory knowledge, any non-trivial Qt application is going to be data-driven, with the data […]
Intro to Qt What to look at when considering Qt as a new development framework
This paper outlines everything you need to take into account when considering Qt as a new framework, so you can decide for yourself if this cross-platform tool is the right choice. It covers: learning curves and initial configurations where to find experts and mentors, or source compatible components which platforms are targeted support for embedded ability […]
