Qt 5.9 has just been released!
This release marks two important milestones for the Qt Project. The first is that now the Qt 5 series has had more releases than any other Qt version ever (the last release of the Qt 4 series was Qt 4.8). The second milestone is that Qt 5.9 will be a Long Term Support release, therefore providing to many users a stable foundation to build their applications upon.
KDAB has been a significant contributor to …
With an apology to English-speaking audiences 🙂
Anche quest’anno KDAB partecipa a QtDay, la conferenza italiana interamente dedicata a Qt. Giunta oramai alla sua sesta edizione, QtDay continua a crescere. Quest’anno QtDay si articola in 3 giorni: il primo dedicato a un training su QML, seguito da due giorni di conferenza vera e propria.
Durante la conferenza terrò due interventi:
(English speaking? Keep reading!)
Il prossimo Giugno parteciperò all’Italian C++ Conference 2017, la più importante conferenza italiana sul C++, sponsorizzata da KDAB.
L’evento è gratuito e si rivolge tanto ai programmatori esperti di C++ quanto a chi voglia avvicinarsi a questo linguaggio. L’edizione di quest’anno prevede due tracce, di cui una completamente in inglese, con ospiti internazionali d’eccezione: Phil Nash, Jens Weller, Bartosz Milewski e Dietmar Kühl.
L’appuntamento è per Sabato 17 …

This year KDAB is proud to be hosting …
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.
Since Qt 5.0, the new-style, PMF-based (pointer to member function-based) QObject::connect will check at compile time if the signal’s signature is compatible with the slot’s one.
For instance, let’s consider these two …
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 series of checks to help you debug these sorts of issues.
First and foremost, are we really …
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 enumerations in QtScript, QtDBus and QML.
The support for all of this involves a few new macros. The most important one is …
Qt 5.8 has just been released! Another great release of Qt, made possible by thousands of commits by over a hundred different contributors:
And here we are again, with the usual showcase of the most outstanding contributions to Qt 5.8 developed by KDAB engineers.
In no particular order:
Qt 3D continues to receive lots of improvements and bugfixes, thanks to the hard work of …
In the last blog post we gave a very high level introduction to the Qt Quick 2 renderer. We also showed how various signals are emitted by the renderer during the synchronization and rendering steps. In this blog post we’re going to discuss those signals and show how they can be used to implement overlays and underlays.
Let’s start again by looking at this diagram of the synchronization between the render thread of …
