The upcoming version of the C++ Standard (C++2a) is proposing to deprecate certain usages of the volatile keyword, by adopting the P1152 proposal (Deprecating volatile). Despite the somewhat “flamboyant” title, the actual deprecated parts are very limited and indeed the paper limits the deprecation to somehow language/library corner cases and/or dangerous antipatterns. For instance certain […]

KD SOAP is a tool for creating client applications for web services. The release of 1.9.0 brings a fair number of improvements and fixes, as the following text describes. General C++11 is now required. Qt4 is still supported, but this is the last release with support for Qt4. rpath for Unix/Linux/macOS (#181) is now fixed. […]
Working on color imagery for QiTissue recently, I realized we were accidentally losing the alpha channel in multiple places. For efficiency reasons, we keep colors in memory using the QRgb type, and convert that to/from QString for serialization purposes via QColor as needed. Here’s what I discovered about why that doesn’t work, and some ways […]
Did you miss the past Qt World Summit? Were you there, but you couldn’t attend that talk or two that you really wanted to see because the conference was so, so packed with awesome content? Fear no more! We are glad to announce that the talks at the past Qt World Summit 2019 in Berlin […]
Supervisory control and data acquisition (SCADA) systems have been around since the 1950’s, far longer than most other types of computer applications. Their rock-solid performance has been responsible for the streamlining of any industry that needs precise and consistent controls: building automation, energy management, part machining, printing and packaging, robotic assembly, ship building, water treatment, […]
Embedded World – 25-27 February 2020 February 2020 will be the tenth year that KDAB exhibits at Embedded World, in Nuremberg, Germany. When we started exhibiting, there were only five halls compared to today’s seven, so the event continues to grow and remain relevant, in a world where most interaction takes place on-line. In those […]
KUESA™ is a solution that provides an integrated and unified workflow for designers and developers to create, optimize and integrate real time 3D content in a 3D or hybrid 2D/3D software user interface. Models, including geometry, materials, animations and more, can smoothly be shared between designers and developers. Kuesa relies on glTF 2.0, an open standard […]
A few days ago Marc Mutz, colleague of mine at KDAB and also author in this blog, spotted this function from Qt’s source code (documentation): Apart from the mistake of considering empty strings not uppercase, which can be easily fixed, the loop in the body looks innocent enough. How would we figure out if a […]
Download the report As the world continues its steady march towards ubiquitous computing, almost everything from airplanes to toasters is being powered by embedded software. In fact, technology is so pervasive, we take connected homes, advanced medical equipment, and self-driving cars almost for granted. However, many of us who work in the industry have some […]
Have you ever noticed code highlighting disappearing in Qt Creator for some projects, without any apparent reason? Can’t get Ctrl+Click to work on any class name or function name anymore? Maybe you have ignored it at first, got used to it, and decided it’s just one of those things that just “happen sometimes”; or maybe […]
