KDSoap is a tool for creating client applications for web services without the need for any further component such as a dedicated web server. KDSoap lets you interact with applications which have APIs that can be exported as SOAP objects. The web service then provides a machine-accessible interface to its functionality via HTTP. Changes in […]

Qt Quick without a GPU: i.MX6 ULL on small embedded devices
With the introduction of the Qt Quick software renderer it became possible to use Qt Quick on devices without a GPU. We investigated how viable this option is on a lower end device, particularly the NXP i.MX6 ULL. It turns out that with some (partially not yet integrated) patches developed by KDAB and The […]
Clazy An open source Clang plugin allowing it to understand Qt semantics
Clazy is a Clang plugin which extends the compiler with over 50 warnings related to Qt best practices ranging from unneeded memory allocations to API misuse. It’s an opensource project spawned by KDAB’s R&D efforts for better C++ tooling. At KDAB, we have a pretty cool Continuous Integration infrastructure to take care of our customers’ […]
Hotspot A GUI for perf report
“I have also done some last minute performance improvements with the help of KDAB Hotspot/perf, and I must say that the days of profiling with weird/huge perf command line options are gone, awesome tool!” Hotspot is a KDAB R&D project to create a standalone GUI for performance data. It is a replacement for perf report. […]
KDAB’s City Lights Display with Qt 3D Qt 3D put to novel use to implement a deferred rendering pipeline
The City Lights demo is an example of Qt 3D being put to novel use to implement a deferred rendering pipeline. With OpenGL, the number of lights you can show on a screen, also affecting objects in a scene, is limited by the need to use a forward renderer. Using Qt 3D, the geometry considerations […]
Exporting 3D content for Qt 3D with Blender
At the heart of every 3D application is geometry. Qt 3D-based 3D applications are no different and require the user to either generate geometry or provide asset files for Qt 3D to load. This blog post demonstrates how Blender and its Python API could be used to write an exporter that generates geometry for Qt […]
GammaRay 2.9.0 Release
We have released version 2.9.0 of our Qt application introspection tool GammaRay. GammaRay allows you to observe behavior and data structures of Qt code inside your program live at runtime. GammaRay 2.9 introduces a number of new features interesting to Qt Quick, QWidgets, Qt 3D and non-graphical Qt users alike. Qt Quick One focus area of […]
