Introduction Back in the days when Qt was owned by Nokia, a development team in Brisbane had the idea of making it easy to incorporate 3D content into Qt applications. This happened around the time of the introduction of the QML language and technology stack, and so it was only natural that Qt3D should also […]

Update: Here you have also the Chinese version, thanks goes to Foruok. After we've seen how to set up the development environment, how to use Qt on Android and what deployment systems are available and how to sign the final package, it's time to move forward. In this article we are going to learn about […]

Touchscreens and modern user interfaces are migrating into every type of medical machine: ultrasound, infusion, CAT, MRI, x-ray, care monitors, surgery displays, information tablets, and even patient self-service systems. Touchscreens are also helping with hygiene requirements as they are liquid-proof and easily disinfected because the display is in a sealed enclosure. Qt is an ideal […]

Hybrid applications, which mix a UI built with Qt Widgets or Qt Quick with embedded HTML websites, are very popular. In particular, something like an HTML 5 app framework is often requested by customers. Qt WebKit makes it trivial to embed HTML content in any graphical application. But how does one bridge the gap between […]

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 […]

In the previous blog post, we talked about the importance of pixels and their indivisible nature, the way we deal with that in the icon area and introduced the concept of PPI dependable UIs - all this to have truly scalable graphics in QML. We used the BorderImage element to illustrate how an element could […]

CMake 3.0 was released last week with many major new features and new Qt integration for uic and rcc. A major change with this CMake release is the new documentation system based on reStructuredText and Sphinx. Sphinx has the ability to generate Qt Assistant files, so these are now easy to create reproducibly from the […]

In my previous blog, I talked about what characteristics made a good app for Qt in the Android environment. I'll paraphrase an insightful response from Artem Marchenko -- my blog post is really talking only about standalone apps, and not Android integrated ones. That's correct--my blog focused on "easy wins" - areas where you could […]

Behind the screen - development of a QML application. Usually we do not get to talk about the innovative solutions our employees find to almost impossible problems on a daily basis - I guess that is just part of life as a consulting company. Recently we developed an in-house application, and that gives us the […]

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 .... […]

The power of Qt running on the ubiquity of Android is a potent combination that can be used to great effect in a number of different applications. But are there certain apps that really shine when they’re built using this dynamic duo? Before I go any further, let me introduce myself. My name is Andy […]

In the last few weeks I've been working on a prose description of how the type-erased container iteration with QVariant works. The existence of the feature and how it can be used was described in my presentation at DevDays 2013. The slides are available here. The video is not available currently, but will be published […]

Urbi et Orbi A new year just started a few weeks ago, but Qt on Android doesn’t have time to rest :). The secret meeting At the beginning of the year I attended a very important workshop in Oslo. For two full days KDAB (me) and Digia (Oslo office folks) secretly discussed the future of […]

The guys at QNX have been doing such great stuff with the QNX Concept Car, we wanted to draw our reader's attention to the fact that, "under the hood" and so not publicized, the awesome entertainment system and the instrument cluster in the Mercedes are done with Qt 5 (QML2 to be precise) on top […]

Qt 5.2 has just been released! Coming only five months after 5.1, the new release brings in a huge number of new features, as well as many bug fixes. For the first time ever, Qt is officially supported on two major mobile platforms: Android and iOS. KDAB contributed over 300 commits to Qt 5.2, both […]

In my first article that I wrote about Qt on Android I gave you a small introduction on how the port began and where is it now. I wrote about the fact that in November 2012 I contributed the port to Qt project, but I intentionally omitted one very important thing to tell you. Before […]
