This 3-part blog series shows in detail how to get up to speed with a Qt project using Visual Studio Code. Part 1 covers workspace setup, adding extensions, build, launch and workspace configurations, and more
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 […]

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 […]
