KDAB is proud to be bronze sponsor at Italian C++ Conference, the largest conference in Italy specifically focused on C++ development for professionals, students and businesses using C++. It's free, organized by the Italian C++ community, and there's Italian icecream to think about too... It's an offer you can't refuse ;) Sign up and see […]

QtDay is the yearly Italian conference about Qt and Qt-related technologies. Its 2018 edition (the seventh so far!) will be once more in the beautiful city of Florence, on May 23 and 24. And, once more, KDAB will be there. I am also glad to announce that my talk has also been accepted: I am […]

This year Qt World Summit was held once more at the Berlin Congress Centre, in central Berlin and had over 1000 attendees – clear testimony to the growth of the Qt Community, as Qt enables our interfaces with the world in multiple areas, from medical to automotive, from gaming to industrial machinery, on desktop, mobile […]

The program for CppCon 2017 is now published! CppCon is the annual conference for the C++ community: five days packed with over 100 talks, as well as inspiring keynotes, panel discussions, hallway chats, fun evening events and much more. CppCon is a project of the Standard C++ Foundation, a not-for-profit organization whose purpose is to […]

On December 1st, KDAB’s Kévin Ottens and David Faure co-hosted a one day Meet Qt in Lyons, with The Qt Company and Witekio. The event was booked out with 50 people attending, confirming the growing community of Qt users in France. Participants were given plenty of opportunities for questions throughout the day and much appreciated […]

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 […]

Recorded at the Qt Developer Days in Berlin in 2014. Abstract: It is easy to be enthusiastic about the technical merits of Qt. For those having to make technology choice decisions that impact the business for potentially a long time, that is not the only dimension, however. Risks need to be examined and trade-offs identified, […]

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 […]

JamesTurner and Giuseppe D’Angelo introducing Qt3D 2.0 Abstract: Qt3D 1.0 was created during the Qt4 life-cycle, and has been deprecated since the release of Qt5. Additionally, the API design featured some limitations which restricted the potential use-cases; injecting large amounts of dynamic data into the scene, configuring advanced multi-pass / deferred renderers, and using multiple […]

Kevin Krammer compares QtWidgets and QtQuick Controls. Abstract: QtWidgets has been one of Qt's selling points throughout its two decade long existence. Its ability to blend into the target platform's look&feel with little or no effort on the part of application developers is unparalleled. The advent of powerful mobile and embedded devices, and later touch […]

Abstract: The new QtWebChannel module is a ready-to-use solution to make any QObject accessible to arbitrary JavaScript clients. KDAB already uses it in production for a client project on embedded devices, where it proofed to be an essential part for the HTML app framework embedded in a QML chrome. Thanks to QObject introspection, any object […]

Abstract: This presentation will start by explaining the concept of inqlude.org and showing some of the libraries available there, pointing in particular to those that will be useful in the rest of the presentation. The multiple ways to use inqlude.org will be discussed: browsing the website and downloading sources, using the command-line tool to install […]

Abstract: Moc's job is two-fold: it generates the qt_metacall() member function that dispatches incoming calls to slots and implements reading and writing of properties, and it generates the QMetaObject containing information about what signals, slots and properties are available, providing runtime introspection capabilities. All of this is fixed at compile time though, a limitation that […]

Abstract: With the launch of the Qt Project in 2011 it has been made possible for everyone, individual or organization, to directly submit patches to the Qt codebase. Whether it's a small fix to the documentation, an improvement to existing code, or even a brand new module altogether, the procedure is the same. The presentation […]

Abstract: It is easier and easier to create a proper QtQuick application from scratch. But is it really that simple to bring existing code in the QtQuick structure? It can get especially challenging for a large project which collected C++ collected over more than 15 years. What can we do of all that code? Temptation […]

Abstract: Qt5 introduces better support for OpenGL from the QPA/Lighthouse abstraction, through a new set of OpenGL classes up to QtQuick 2 and Qt3D. OpenGL is also very often used for games and as the central content widget in desktop applications. With the advent of QtQuick 2 it is now easy to write entire user […]

Abstract: Modern OpenGL abandons the old fixed-function pipeline in exchange for a programmable pipeline using shaders and buffer objects. This offers much more flexibility to developers and opens the door to a huge range of effects and techniques whilst at the same time making available huge performance improvements. This presentation will teach you about the […]
