Having 3D scenes in your application is becoming a clear trend and is likely to become even more important in the future with the growth of Virtual Reality and Augmented Reality. So far Qt was allowing you to integrate with Open GL fairly easily, but managing the rendering code itself was still a very challenging […]
Using OpenGL code with Qt is a long love story... long enough that there might be skeletons in the closet. Indeed, the OpenGL code of your Qt application could have been written before the modernization of the OpenGL API to exploit better GPUs. In this talk, we will walk through a technique to help refactor […]
3D scenes in applications are becoming increasingly important with VR/AR growth. While Qt allowed OpenGL integration, managing rendering code remained challenging. Qt 5.7's new Qt 3D module eases 3D scene creation through its API, but functions as a complete simulation engine capable of much more than just 3D rendering.
A retrospective on the KDE community from 20 years ago and how things were done back then, with an emphasis on community spirit and fun facts. Over time, the KDE community has seen many people join and leave, as with any open source community, which means that very few people in the current community still […]
The past year was very important for the KDE PIM community. We released the first Qt5-based version, restructured our code base and set ourselves more ambitious goals. Let's look a bit deeper into some of the important changes that have happened in KDE PIM in the past year, and peak a little into the future. […]
Using OpenGL code with Qt is a long love story... long enough that there might be skeletons in the closet. Indeed, the OpenGL code of your Qt application could have been written before the modernization of the OpenGL API to exploit better GPUs. In this talk, we will walk through a technique to help refactor your old OpenGL code in the safest way possible and get it ready for the 21st century.

In this session we'll see real life examples of using JNI on Android. We'll start by checking the Qt 5.7 goodies which will make our lives easier, then we'll see simple examples that you'll need to use in almost any Qt on Android application, and we'll end up with an Android Service made with Qt. […]
This KDE community retrospective explores development culture from 20 years ago, emphasizing community spirit and fun facts. It shares initial KDE culture with current generations, including surprising development practices (pre-CVS version control) and highlights how architectural elements now considered fixed were once subject to greater creativity, potentially encouraging renewed innovation.

Physics Based Rendering (PBR) is the latest and greatest trend in real-time rendering yielding much more visually believable images than the traditional Phong or ad-hoc lighting models. The underlying concept is that the shaders should use physical principles in the encoded models - chief of which are conservation of energy and the Fresnel effect. PBR […]

Many KDAB engineers are part of the Qt Security Team. The purpose of this team is to get notified of security-related issues, and then decide the best course of action for the Qt project. Most of the time, this implies identifying the problem, creating and submitting a patch through the usual Qt contribution process, waiting […]
Design, Technical Excellence and Superb User Experience Why does a tipper truck need an app? Meiller is the leading manufacturer of tippers in Europe. KDAB software developers and UI/UX designers worked with Meiller to create a mobile app that interacts with embedded hardware on the truck, allowing drivers to diagnose and fix problems - even […]
Why does a tipper truck need an app? F.X. Meiller is the leading manufacturer of tippers in Europe. KDAB software developers and UI/UX designers worked with Meiller to create a mobile app that interacts with embedded hardware on the truck, allowing drivers to diagnose and fix problems - even when on the road. KDAB shows us how technical excellence and stunning user experience go hand in hand.
GammaRay 2.6 brings you three major new features: We merged the previous model and selection models tools into a new, unified QAbstractItemModel inspector, allowing you to now also see selections and cell flags, as well as to inspect deactivated cells. The new Wayland compositor inspector enables you to observe Wayland clients of a QtWayland compositor, […]
Hello! This is a small wrap-up fromQtCon, the biggest Qt event in Europe in 2016, that happened at the beginning of September. At QtCon the Qt community joined forces with the KDE, FSFE and VideoLAN communities, to create an exciting event in the spirit of open collaboration and participation amongst projects. During QtCon many KDAB […]
Starting with Qt 5.7, we added the ability to create Android services using Qt. In this article we're going to see how to get started and also how to communicate between the two. Before we get started I want to add a big bold WARNING about the performance! Because the services are run in the […]
We had a huge amount of fun at QtCon in Berlin. By far the most commented on was the positive effect of the diversity of attendees, both newcomers (about 30%) and those who came through the five entities involved in bringing the event together: KDAB, Qt Contributors, KDE Akademi, FSFE and VideoLAN, notable also for […]
Q_FOREACH (or the alternative form, foreach) will be deprecated soon, probably in Qt 5.9. Starting with Qt 5.7, you can use the QT_NO_FOREACH define to make sure that your code does not depend on Q_FOREACH. You may have wondered what all the fuss is about. Why is there a continuous stream of commits going to […]
