Stay up-to-date and get inspiration from KDAB’s expert insights into Qt, C++ and OpenGL development.
Our engineers and designers share cutting-edge technology news and ideas with regard to Qt, QML, Qt on Android, OpenGL, Qt 3D, Vulkan, Scalable UIs and more embedded, mobile and desktop-related topics.
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 […]
Introduction Following on from the previous articles on SlideViewer, we shall now investigate another piece of the puzzle towards making SlideViewer usable in practise. Namely, getting the content rendered from our domain specific language and on to the screen or projector for the audience to marvel at. Those of you that have ever presented at […]
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. On the other hand, it’s expected that Designers […]
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 bring 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 […]
erratum 2014-04-13: Updated Bundle Qt libs pros and cons. Update2: Here you can read also the Chinese version, thanks goes to Foruok. After we’ve learned how to set up the development environment and how to use Qt on Android, it’s time to move forward and in this article we are going to learn about different […]
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 […]
