It is often said that QML is a declarative programming language. But what does it mean? A cornerstone of the meaning is the ability of properties to be linked to each other, creating so-called property bindings. In this video we explore the semantics of bindings across different elements.

This video showcases an exercise from our QML training course, where students are asked to reproduce a simple UI using Qt Quick and QML. As a side product, they learn more about positioning Qt Quick elements in a scene.

The first in a video series that teaches the foundations of programming with Qt Quick / QML. The content is extracted from our highly rated "Introduction to QML" training course regularly taught around the world by KDAB engineers. This video shows how to recreate the famous "Hello World" example using Qt Quick and QML. You will learn how to actually go from a QML source file to having a standalone running executable, that indeed shows the "Hello World" text.
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 for their innovative electric scooter. In this video you learn more about the development process in this project, some technical info and why unu chose KDAB as a partner.
This video offers an example of rich 3d visualization KDAB helped create for QI Tissue to make sense of hugely complex and vast datasets now available to researchers in the search for a cure for cancer.
In this video, the third part of a series on using Kuesa 3D Studio, Timo Buske of KDAB gives an overview of the preparation of 3D assets for realtime export, including optimising meshes and creating a scenegraph.
Celebrating 20 years at the top of the league in Qt, C++ and 3D consulting, in 2019, KDAB's founder and CEO, Matthias Kalle Dalheimer reflected on how we got there.
Hotspot is a KDAB R&D project to create a standalone GUI for performance data. It is a replacement for perf report. Hotspot’s GUI takes a perf.data file, parses and evaluates its contents and then displays the result in a graphical way.
KDAB's Christoph Sterz shows how to use GammaRay and the latest updates (2019) in this short video. GammaRay allows you to examine and manipulate the internals of Qt / QML applications at runtime. It augments conventional debuggers by understanding the implementation of Qt, allowing it to visualize application behavior on a higher level, especially where complex frameworks like scene graphs, model/view or state machines are involved.
Kuesa 3D Studio is a solution that provides an integrated and unified workflow for designers and developers to create, optimize and integrate real time 3D content in a 3D or hybrid 2D/3D software user interface. Here, Timo Buske shows how to create a fully interactive 3D app using Kuesa 3D Studio. Kuesa 3D Studio is available for both embedded or desktop applications.
With Kuesa, designers can use the professional 3D design tool they prefer to create the 3D scenes. 3ds Max®, Blender, and more to come, all have the features needed to create stunning animations in an efficient way. The Kuesa digital content creation plugins integrate into the 3D design tool to add new features. KDAB's Timo Buske explains.
For SIGGRAPH 2018, KDAB worked 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. We used QtQuick and the Qt 3D QML API to declare the UI and instantiate the 3D scene and Python for the backend logic, data processing and models as well as definition of the custom Qt 3D meshes elements we needed to use in the UI.
German company OPW produces ultra high-quality measuring instruments and devices designed to help manufacturers ‘get it right first time.’ KDAB redeveloped the software using QML for the UI to enable OPW's in-house technician to set up the control panel, thus improving quality management and long-term cost-savings.
With the introduction of the Qt Quick software renderer it became possible to use Qt Quick on devices without a GPU. We investigated how viable this option is on a lower end device, particularly the NXP i.MX6 ULL, with positive results as this demo explains.
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’ […]
The City Lights demo showcases Qt 3D's novel implementation of deferred rendering pipeline. Unlike OpenGL's forward renderer which limits the number of on-screen lights, Qt 3D separates geometry from lighting considerations, massively reducing complexity. This enables the demo to run at 60fps on modest hardware despite containing approximately 1500 real-time lights.
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 Qt5 is a job where proven experience saves a lot of time.
Qt World Summit 2017 in Berlin attracted over 1000 attendees, demonstrating Qt Community growth across medical, automotive, gaming, and industrial applications on desktop, mobile, and embedded platforms. KDAB hosted a pre-conference training day for 500+ participants with 11 sessions, including an Advanced QML class for 115 students. As Diamond Sponsor, KDAB showcased stunning demos at their largest booth.
