If you’re a reader of this blog, you probably know that we have a huge amount of quality material on QML and Qt Quick, among other topics. In fact, there is so much material that it can be hard to find what you need. If that sounds familiar, you’ll want to bookmark this page! This […]

Software has become a critical factor of our economy. Manufacturing companies must start to think and act software-centric to survive. In this interview, software pioneer Matthias Kalle Dalheimer explains why conventional companies run the risk of becoming commoditized and how they can get ahead of the competition. What are the corner stones of a real […]

Wrapping up Qt Desktop Days, are two final sessions that cap off five days of great sessions. Kirigami: convergence with Desktop as first-class Let’s say you want to develop a mobile-looking UI... hey, wait a minute! Aren’t we talking about Qt Desktop Days? Indeed we are, but as Marco Martin, a KDE employee who works […]

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 great content from Qt Desktop Days continued on day three. QML for Desktop If you’re building a desktop application today, should you consider building the UI with Qt Quick? That’s the question that KDABian Shantanu Tushar answers in this session. He walks us through the pros and cons of Qt Widgets versus Qt Quick, […]

What sessions were on the second day of Qt Desktop Days? Lots! QGIS loves Qt! The first session on day 2 was from Nyall Dawson who works for North Road but who is also a significant contributor to QGIS, the largest open-source GIS program in the world. Nyall explains why Qt is an awesome fit […]

If you missed Qt Desktop Days, you might be wondering what you missed. No need to worry! We’re going to give you a day-by-day summary of some of the cool things that were discussed, demoed, and explained. (We’re uploading all of the videos to our YouTube channel, but we’ll provide the direct links to each […]

Up until now, Qt 3D was relying on OpenGL for rendering. With the upcoming Qt 6, Qt will come with a rendering abstraction layer (Rendering Hardware Interface or RHI) to target not only OpenGL but also Vulkan, Metal and DirectX. We are in the process of adding RHI support to Qt 3D. This will allow […]

KDAB's Kevin Funk presented Using Modern CMake with Qt at Qt Virtual Tech Con last month. He reported that the Qt Company did a great job moderating the sessions at this event, and there was a lively Q&A at the end - Kevin had to pick from about 60 questions, so this is a hot […]

Did you miss the past Qt World Summit? Were you there, but you couldn't attend that talk or two that you really wanted to see because the conference was so, so packed with awesome content? Fear no more! We are glad to announce that the talks at the past Qt World Summit 2019 in Berlin […]

Right from the start, unu wanted to add a stylish, first-class embedded high-res display to their second generation electric scooter. Like many top-class engineering companies, unu didn’t have in-house expertise for building a modern UI, so they decided to partner with KDAB to build a modern UI based on Qt. In this video you learn […]

For SIGGRAPH, KDAB has been working on a new Qt 3D based demo. We decided that instead of using C++, it would be interesting to try out PySide2 and harness Python to drive the application. The idea behind this demo is to do with data acquisition of a vehicle's surrounding environment. Once the data is […]

Thanks for joining us for this year's edition of Meet Qt that took place in Paris on the 19th June. The focus this year was medical and automotive and the event was again very successful despite the train strikes. If you could not attend here is an idea of what KDAB offered: A medical client's […]

Clazy is a Clang plugin which extends the compiler with over 50 warnings related to Qt best practices ranging from unneeded memory allocations to API misuse. It’s an opensource project spawned by KDAB’s R&D efforts for better C++ tooling. At KDAB, we have a pretty cool Continuous Integration infrastructure to take care of our customers’ […]

"I have also done some last minute performance improvements with the help of KDAB Hotspot/perf, and I must say that the days of profiling with weird/huge perf command line options are gone, awesome tool!" Hotspot is a KDAB R&D project to create a standalone GUI for performance data. It is a replacement for perf report. […]

The City Lights demo is an example of Qt 3D being put to novel use to implement a deferred rendering pipeline. With OpenGL, the number of lights you can show on a screen, also affecting objects in a scene, is limited by the need to use a forward renderer. Using Qt 3D, the geometry considerations […]

Some of you may know that KDAB employees enjoy flexibility on working hours as well as location, and some choose to work from home, with the opportunity to share childcare, do part-time study or simply enjoy an out-of-the-way location. All that's required is a decent bandwidth for KDAB work. About once a year, all of […]

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 […]

KDAB has unique experience in porting the code base for toolkits like Qt 3, Qt 4, Motif, Java, Tcl, GTK, .NET, MFC, and Photon to Qt 5. Porting legacy GUI toolkits to Qt 5 is a job where proven experience saves a lot of time. In this presentation we highlight the main problems facing developers […]

Solving cancer is probably the biggest mystery that we see unravel in our life. This is a complex one because cancer is not a single disease, there are a myriad of aspects that need to be uncovered. Qi (Quantitive Imaging Systems) images biopsies from patients and then labels individual cells with over a hundred biomarkers. […]
