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 […]
Qt Developer Conference A Conference from Developers for Developers
We at KDAB are pleased to announce an event we’re planning to host in Berlin this fall, September 28-30. Save the dates for KDAB’s Qt Developer Conference — a conference from Qt developers for Qt developers! Qt Desktop Days, May 2021 — Cancelled Before we tell you more about Qt Dev Con, we’d like to […]
Discover Bottlenecks on QNX How to Speed Up the Process
For many developers, QNX is the operating system of choice, when it comes to developing on embedded systems. However, the performance limits are exceeded quickly, especially if you’re working on low-end hardware. As a result, you’ll likely need to perform an investigation to find the bottlenecks that contribute to reaching these limits, in order to […]
Single-Shot Signal/Slot Connections
Sometimes it’s useful to establish a connection between a signal and a slot that should be activated only once. This is not how signal/slot connections normally behave. Remember that, when a connection is established, it will stay active until: the connection is explicitly disconnected; or the sender object is destroyed; or the receiver object is […]
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 […]
Qt Desktop Days Returns! CFP now open!
The event has been cancelled and will be integrated into our Qt DevCon event in June 2022. KDAB is bringing you another Qt Desktop Days this May! So, if you missed the first one that was held last September, or if you would like to attend a second, please join us May 19th-20th. That’s a […]
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: […]
Qt Embedded Days 2021
This brand new online conference hosted by KDAB offers in-depth technical topics from embedded developers for embedded developers – especially, but not exclusively, for those working with Qt on Embedded Devices. The call for papers is now closed and the program will be announced as soon as the committee has made a final selection. We […]
