Introduction At Qt developer Days in Berlin 2013 I had an Aha! moment. I saw a presentation written in QML rather than the usual Powerpoint/LibreOffice/Keynote. It wasn't that I did not imagine this was possible, rather the contrary, after all in KDAB we have more than 3000 slides on Qt-related topics, all written in .... […]
Creating 3D applications can be overwhelming due to terminology, visual concepts, and advanced math. KDAB simplifies this task, providing you with the best solution for your 3D project, easing complexities and maximizing efficiency.
The last post from my colleague Marc Mutz about deprecating Q_FOREACH caused quite an uproar amongst the Qt developers who follow this blog. I personally feel that this was caused fundamentally by a perceived threat: there is a cost associated to porting away a codebase from a well-known construct (Q_FOREACH) to a new and yet-undiscovered […]
As was previously discussed, since the 6.0.0 release of Qt, Qt 3D no longer ships as a pre-compiled module. If you need to use it on your projects, try out the new features, or just see your existing application is ready for the next chapter of Qt's life, you need to compile Qt 3D from […]
As mentioned in the previous article in this series, Qt 3D 5.14 is bringing a number of changes aimed at improving performance. Most people familiar with Qt 3D will know that the API is designed around the construction of a scene graph, creating a hierarchy of Entities, each of them having having any number of […]
The build system for Qt is CMake. What are the benefits of CMake, and how can it help transform your build system? This whitepaper gives you the basic facts so you can take advantage of CMake for building Qt applications.
In the final part of our series on 3D in Qt 6, we review the tooling around 3D, and how the different approaches available suit different business and technical needs. We look at what content creators typically deliver to us as developers, what operations and actions we might do with that, and how iterative development and revisions to content impacts us a developer.
As there were some complex issues around conformity in PDF document creation within Qt, KDAB let me spend some time digging into it so we could make sure that Qt's PDF engine generates documents up to ISO-standard. Nowadays, many official institutions have the requirement to archive their data digitally and PDF is a first class […]
This 'Insights' series video interviews Bruno Coudoin, creator and founder of GCompris, about what inspired him and the software's success. GCompris is free, open-source educational software for kids aged 2-10, built with Qt. Topics include his motivation, open-source approach, development challenges, family support, contributors, project handover, and seeing governments adopt GCompris in school curricula.
Back in November, Apple released the latest generation of it's Apple TV product. Besides the slightly improved hardware, the true new feature is the OS which is now officially based on iOS and comes with the dedicated SDK and App Store! So we started investigating what it would take to port Qt to tvOS and […]
To successfully develop an embedded device that meets your expectations regarding quality, budget and time to market, all parts of the project need to fit perfectly together. Learn more about KDAB's expertise in embedded software development.
All Qt developers have asked themselves at least once in their careers: "why isn't my slot invoked?" (I've asked myself that question many, many times). There are a number of reasons why a connection may fail to be properly set up, and ultimately cause our slot not to be invoked. This blog post is a […]

In a recent email, KDABian Leon Matthes highlighted some of his go-to command line tools for everyday use on Unix. His recommendations sparked a lively exchange among our colleagues, each sharing their own favorite utilities. Many of these tools offer efficient alternatives to standard Unix programs, speeding up the workflow or otherwise enriching the development […]
