Software migration is a lengthy process that sees hundreds of modules move from an obsolete framework to a much more preferable one. However, there are a number of pitfalls in a large porting effort that can significantly increase time, cost, and complexity, leading to risk of project derailment. Regardless of what your current system was […]

CppCon 2017: trip report
During the last week of September I attended the 2017 edition of CppCon, in Bellevue, WA. Unusually late due to my presence at Qt World Summit which took place just after it, here’s my trip report.
Qi (Quantitive Imaging Systems) case study Solving Cancer with Qt 3D
Solving cancer is probably the biggest mystery that we see unravel in our life. This is a complex one because cancer is not a single disease, there are a myriad of aspects that need to be uncovered. Qi (Quantitive Imaging Systems) images biopsies from patients and then labels individual cells with over a hundred biomarkers. […]
KDAB, MyScript and Qt Company to create new, non-distractive input method for the Automotive Industry
KDAB will be partnering with MyScript and The Qt Company to incorporate MyScript’s handwriting input technology into the Qt Automotive Suite. This integration will enable multimodal input capabilities using either the existing Qt Virtual Keyboard or a new handwriting input panel powered by MyScript technology. KDAB’s Jan Arne Petersen demonstrated some of the potential of […]
Clazy Results Visualizer for Qt Web UI to view clazy and gcc warnings
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. Today, we’re proud to announce a Clazy Web UI to view all warnings emitted by Clazy, […]
Hotspot v1.1.0 adds timeline and recording features New release of the GUI for the Linux perf profiler
Close to three months after the initial hotspot release, I’m happy to announce the release of version 1.1.0. Quick recap: Hotspot is a graphical frontend to the Linux perf profiler suite. It allows you to visually analyze perf.data files with the built-in Flame Graph and the Bottom-Up, Top-Down, or Caller-Callee data tables. It is a […]
Competence Center (CCI) case study Putting intelligence into agriculture using Qt
When Competence Center ISOBUS (CCI) decided to bring their terminal up-to-date as part of the Group’s strategy to remain top of the field in advanced agritechnical innovation, they asked KDAB to help. The user interface in the operator’s cab displays multiple applications. It can control complex agricultural tools, receive and display complex reports and much […]
GammaRay 2.8.1 Release
We have released version 2.8.1 of our Qt application introspection tool GammaRay. This release contains a number of important bugfixes as well as support for Qt 5.9.2. Especially if you are experiencing corrupt views or crashes when searching in the object tree, or having trouble attaching to a process on Windows, you want to upgrade […]
Lots of lights: Generating cities Data visualization with Qt 3D, OpenGL and C++
Sometimes data visualization might call for more than a graph – you need to visualize complex data, such as that generated by city lighting, in three dimensions to get the full effect. KDAB decided to put together a showcase for the Qt World Summit that allowed us to demonstrate Qt 3D’s capabilities as a performant […]
Profiling QtQuick HMI Performance on Embedded Linux Demo of a QtQuick speedometer running on an i.MX6 board
QtQuick is a popular choice for creating HMIs for embedded devices. The hardware on these devices is often constrained and less performant than their desktop equivalents, this requires extra care from software developers in delivering a fluid user experience. KDAB is regularly involved in improving the performance of QtQuick HMIs on such devices for their […]
