KDAB talks at Qt World Summit 2019 November 4 - 6
The agenda is published and KDAB engineers are offering a wealth of technical talks this year. Optimizing the Rendering of Qt Quick 2 applications, Giuseppe D’Angelo If you have ever wondered how Qt Quick applications are rendered to the screen, and how to use that knowledge to find and fix performance problems, then this talk […]
KDAB at Squish Days Europe, Munich Oct 17-18, 2019
KDAB will be supporting our training partner, froglogic, at this event in Munich dedicated to Squish, the automated GUI tester we are proud to support. Complete with live demo-ing, Tobias Naetterlund, KDAB’s foremost Squish expert, will be giving a talk showing how to control multiple clients simultaneously on one or more machines, using this versatile […]
Little Trouble in Big Data – Part 3 dealing with bottlenecks
In the previous two blogs in this series I showed how solving an apparently simple problem about loading a lot of data into RAM using mmap() also turned out to require a solution that improved CPU use across cores. In this blog, I’ll show how we dealt with the bottleneck problems that ensued, and finally, […]
3D – Interactions with Qt, KUESA and Qt Design Studio, Part 2
In my last post, I went through a method of creating a simulated reflection with a simple scene. This time I’d like to take the technique and apply it to something a bit more realistic. I have a model of a car that I’d like to show off in KUESA™, and as we know, KUESA […]
GammaRay 2.11.0 Release
We have released version 2.11.0 of our Qt application monitoring tool GammaRay. GammaRay allows you to observe behavior and data structures of Qt code inside your program live at runtime. GammaRay 2.11 comes with a new inspection tool for Qt’s event handling, providing even more insights into the inner working of your application. Besides looking […]
Little Trouble in Big Data – Part 2 improving CPU utilization across cores
In Part 1 of this series we solved the problem of using mmap() to load large set of data into RAM all at once. The catch was that it still took too long. In this blog, I describe how we solve this.
KDAB at SIGGRAPH – 2019 July 28 - Aug 1, Los Angeles
KDAB is sharing the Qt booth at SIGGRAPH in Los Angeles. We’ll be showing some of our profiling and debugging tools as well as our latest QiTissue demo, a desktop Application developed for Quantitative Imaging Systems (Qi) to help cancer researchers efficiently handle gigabytes of data (see more about that here), We’ll also give a preview […]
3D – Interactions with Qt, KUESA and Qt Design Studio, Part 1 how to create a reflection with minimal computational effort
Neither KUESA or Qt 3D Studio will give free reflections. If you know about 3D, you know it requires ray tracing software, not OpenGL. So, I wondered if there would be an easy way to create this effect.
