New in Qt 6.1: std::hash Support for QHash
In the previous blog post of this series, we discussed KDToolBox::QtHasher, a helper class that allows us to use unordered associative containers datatypes which have a qHash() overload but not a std::hash specialization. The majority of Qt value classes indeed are lacking such a specialization, even if they do provide a qHash() overload. For our […]
Can’t the Compiler Do That? Customized C/C++ Tooling with Clang LibTooling
Note: This is the English translation of the article first published in German Intro The ESE Congress is one of the lead events for Embedded Software Engineering in Germany. This year it was held digitally for the first time, so that participation was also possible via video. Over five days, there were 3 keynotes and […]
Signal/Slot Connection Throttlers
Another day, another blog post about KDToolBox, KDAB’s collection of miscellaneous useful C++ classes and stuff. Today, we’ll talk about ways to throttle your signal/slots connections — in other words, how to activate a slot less often than the emission rate of the signal it’s connected to. The usual reason why you may want something […]
Using Qt Datatypes in Standard Library Unordered Containers
In the previous blog post about qHash, we explained: how to declare an overload of qHash for your own datatypes, how to hash Qt datatypes for which Qt does not provide a qHash overload, and why you can’t use a type from the Standard Library (or just another library) as a key in QHash (newsflash: […]
Kann das nicht der Compiler machen? Maßgeschneidertes C/C++ Tooling mit Clang
Einleitung Der ESE Kongress ist die Leitveranstaltung für Embedded Software Engineering in Deutschland. In diesem Jahr fand er erstmals digital statt, so dass die Teilnahme auch per Video möglich war. An fünf Tagen gab es 3 Keynotes und 96 Fachvorträge aus allen Bereichen der Embedded Softwareentwicklung. Anton Kreuzkamp von KDAB sprach über maßgeschneidertes Code-Refactoring mit […]
KDSingleApplication: a class for single-instance policy applications
Another day, another blog about some of KDAB’s utility classes. Now it’s the turn of KDSingleApplication, a class that helps implement applications that follow the single-instance policy. What is a single-instance policy? Single-instance policy refers to those applications that want to spawn a unique instance for a given user session. Even when launched multiple times, […]
Beware of Qt Module-wide Includes Save the planet by reducing compilation times!
You know the drill: in C++ you need to #include header files that declare the types and functions from the libraries that you use. Qt is no exception in this regard. Qt follows a very nice convention for its own datatypes: if you need to use a type called QType, then use #include <QType>. This […]
How to build Qt with the Address Sanitizer on Windows
Some time ago, I wrote about how to build C++ projects with ASAN on Windows. Now, if you happen to deal with Qt projects you may want to take this one step further and sanitize Qt itself. Why bother with a sanitized Qt build? Let’s have a closer look on why having a sanitized Qt […]
Qt and the unu dashboard
KDAB has been working closely together with unu to create the dashboard application for their next-generation of electric scooters. You can find out about these affordable, innovative, urban transport solutions and book a test ride here. unu is now launching the scooters. So in this blog post, we will have a look at some of […]
