In the earlier post, we talked about the difficulty of scaling Uis across the current PPI range we have on the mobile and embedded space. We also hinted that the most common way to avoid this problem was done via providing several image assets that help to mitigate this issues. How does it work? How […]

A User Experience is not defined to exist in a single form factor any more. It is expected to be able to flow from one device to another, seemingly adapting itself to each interaction paradigm, and yet retain branding, mood and overall look and feel across multiple platforms.

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 […]

Each of these will be a free, three-hour, hands-on session that delves into the internals of Qt on Android. Learn how to: set up the Qt development environment for […]

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 […]

GammaRay 2.0 beta release came out on Friday, January 10th and the final GammaRay 2.0 was released on January 17th. GammaRay 2.0 has a largely reworked core compared to the previous versions, enabling remote debugging. That's especially useful for working on embedded systems, but also helps minimize interference with the inspected process on the desktop. […]

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 […]

As you might already know, we are working on a type-safe template-based SQL support, SQLate, which allow you (among others) to get rid of string-based SQL queries in your Qt application. We are very proud of this new tool so naturally we decided to present it to the public during the Qt Developers days in […]
