If you ever need to create a project around a single C++ file (or just a few C++ files) in CMake, as you might for quick test cases, you might find it tedious to write a CMakeLists.txt file by hand every time. To make this easier, I've written a script called cmake-project that you can […]

Note: This is the English translation of the article first published in German Intro The ESE Congress is one of the lead events for Embedded Software Engineering in Germany. This year it was held digitally for the first time, so that participation was also possible via video. Over five days, there were 3 keynotes and […]

This blog post showcases Spix, a small but useful library for automating GUI-interaction in your Qt/QML-based applications. Just sending clicks or entering text to checking properties, Spix offers basic automated interaction. Combining the automated screenshot function with computer vision, you can even perform simple optical checks with Spix.

This tutorial shows how to display Qt Widget windows in a Qt Quick application, combining the flexibility of both frameworks. Learn how to manage integration through C++, expose widget properties and signals to QML, and build multi-window UIs for desktop or embedded platforms from real world examples.

Creating applications for cross-platform compatibility is a modern best practice. It increases deployment flexibility and allows applications to reach a wider audience. However, doing it properly can involve some trial and error. At KDAB, we’ve built many multiplatform desktop applications. Here, we’ve compiled a few insights from that process to help you build better software. […]

You've reached the third and final entry of the Instantiating arbitrary Qt Quick components with JSON series. Part 1 and Part 2 can be found at their respective links. The first part focuses on the software design pattern used to dynamically instantiate components. The second one shows how to layout these dynamic components by incorporating […]

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, […]

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. Today, we're proud to announce a Clazy Web UI to view all warnings emitted by Clazy, […]

A couple of months ago, Jesper Pedersen introduced our presentation tool for trainings, called SlideViewer. As SlideViewer is mainly used for our Qt and Squish trainings, we naturally have many code examples on the slides, ranging from C++ and QML to Python and XML. In this blog post, we will take a closer look at […]

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 .... […]
