We host a rich array of both Showcase and Presentation Videos created by KDAB’s experts. Many of the presentations detail cutting edge techniques and tools that our engineers have devised to solve the wide diversity of issues currently facing serious developers. Watch and learn!
Are you a Qt developer and do you use Linux as your development platform of choice? Then this talk is for you: I will introduce you to perf, the Linux tool suite for performance analysis. The talk will not only cover a broad part of what perf has to offer, it will also dive into […]
Qt Quick and QML provide an easy way to rapidly develop customized, reusable components entirely within QML. As these components grow in complexity, performance and maintainability often suffer, a drawback that is especially noticeable on low-powered embedded and mobile devices. In addition, some specialized components simply cannot be implemented by combining existing Qt Quick items […]
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 […]
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 […]
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. […]
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 […]
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. […]
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 […]
Till Adam speaks about why Qt matters in the Big Picture.
Using the QML engine and QtQuick scenegraph to introspect and analyze performance. Abstract: A fluid and performant user interface in QtQuick applications is an important factor, especially considering that users increasingly demand an “iPhone-like” experience, while at same time, applications often run on a resource-constrained embedded system. What can be done when a QtQuick application […]
