As an Easter treat here is a quick taster of some of the animation goodies coming to Qt 3D along with Qt 5.9. In this post we will briefly outline the steps needed to create a simple Qt 3D application and the assets it uses to produce this little animation:

Disabling narrowing conversions in signal/slot connections
A small new feature that I have added to Qt 5.8 is the possibility of disabling narrowing conversions in the new-style QObject::connect statement. In this short blog post I would like to share with you why I thought this was useful and therefore implemented it. The problem Since Qt 5.0, the new-style, PMF-based (pointer to […]
QStringView Diaries: The Eagle Has Landed QStringView merged for Qt 5.10
After two months of intensive reviews, discussions, fixes, and stripping down the initial commit, feature by feature, to make it acceptable, I am happy to announce that the first QStringView commits have landed in what will eventually become Qt 5.10. Even the docs are already on-line. This is a good time to briefly recapitulate what […]

KDAB and Qt at Embedded World Nuremberg
Embedded World Nuremberg was bigger than ever this year (over 30,000 visitors!), with a large number of exhibitors displaying “Qt friendly” signs in Hall 4, showing how far we’ve come in recent years This year KDAB exhibited alongside The Qt Company and other Qt partners at one gigantic stand devoted to all things Qt. Automotive […]
What do I do if a slot is not invoked? A practical checklist to debug your signal/slot connections
All Qt developers have asked themselves at least once in their careers: “why isn’t my slot invoked?” (I’ve asked myself that question many, many times). There are a number of reasons why a connection may fail to be properly set up, and ultimately cause our slot not to be invoked. This blog post is a practical […]

Come and visit KDAB and our Qt partners at stand 4:258 at the largest exhibition of its kind in Europe: Embedded World Nuremberg.
New in Qt 5.8: meta-object support for namespaces Using namespaces in Qt for enumeration introspection
A small new feature that was added to Qt 5.8 is the ability for moc (Qt’s meta-object compiler) to extract meta-object information at the namespace level. This means, for instance, that you can have introspection support for enumerations defined in a namespace (not just in QObject subclasses, or classes tagged with Q_GADGET), and use such […]
Heaptrack v1.0.0 Release First stable release of the fast Linux heap memory profiler
I’m extremely happy to finally announce the first stable release of heaptrack, the FOSS heap memory profiler for C/C++ Linux applications. You can download the source tarball from the KDE mirrors: https://download.kde.org/stable/heaptrack/1.0.0/src/ Heaptrack is a fast heap memory profiler that runs on Linux. It allows you to track all heap memory allocations at run-time. Afterwards, the accompanying GUI […]
