In the last blog post we gave a very high level introduction to the Qt Quick 2 renderer. We also showed how various signals are emitted by the renderer during the synchronization and rendering steps. In this blog post we’re going to discuss those signals and show how they can be used to implement overlays […]

C and Its Offspring: OpenGL and OpenCL – Parts 1 & 2 OpenGL Speeds High-End Graphics for On-Chip GPUs
An in-depth look at improving the visual quality and computational throughput of systems with OpenGL, from a KDAB expert and the maintainer of Qt 3D, writing for the USA’s premium magazine for embedded computing: RTC magazine.
What is GammaRay? 3 reasons to start using it today
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 […]
