What is GammaRay? For starters, it’s a powerful electromagnetic wave, as well as a way to treat cancer. It’s also an under-appreciated German speed metal band. And it’s what gives Dr. Bruce Banner his big green alter ego. But Qt aficionados will know the GammaRay that we’re talking about is an uber-powerful Qt debugger and introspection tool. If you’re […]

Efficiency Matters! Streamlining your Modern UX with Compressed Textures
Your mobile app is running slowly, crippled by virtual memory swapping and chunks of the UX aren’t showing. The QOpenGLTexture class (a KDAB contribution), provides the APIs to use compressed textures.
Embedding QML: Why, Where, and How
If you’re already using QML in Qt, you know that it can help quickly create flexible user interfaces using little or no C++ programming. With a basic text file and some JavaScript logic, you can put together a pretty sophisticated interface like that shown in the Qt Quick Clock demo (below) with a minimum of […]

Highlights of CppCon 2015
Oh my, how time flies by! One month ago, I had the pleasure to travel to Bellevue, Washington, to attend CppCon 2015. It was a blast, and as a C++ developer, easily the best conference I ever attended. Below, I try to summarize my personal highlights of the talks I attended live. Note however that there were up […]
How to integrate OpenGL code with Qt Quick 2 applications (part 1)
The Qt World Summit was a rocking blast! More than 800 delegates, two days packed with sessions (and an additional training day presented by KDAB). Many old faces, lots of new ones, and a packed programme of sessions with terrific technical content. Yours truly also happened to give a talk, “Integrating OpenGL with Qt Quick […]

Qt 5.6 with support for Windows Embedded Compact 2013 KDAB presents Qt 5.6 with support for Windows Embedded Compact 2013
It has been a few months since my last update about the Windows Embedded Compact (WEC) port of Qt. But as I promised last time, I have been working on the WEC2013 support for Qt. Not only because it’s the new embedded platform from Microsoft, but also because Qt wants to adopt more C++11 in […]

Now, in the UK, you can easily get the top quality experience you have come to expect from KDAB’s expert trainings at our Berlin facility […]
How to use static analysis to improve performance
It’s usually said “only improve performance where a profiler tells you to“. I don’t completely agree. Take a big C++ library like Qt: can you profile all classes and all code paths ? It would take a couple of years to accomplish and analyse the results. It’s expensive: It usually only happens if the speed-up […]
