After many months of work, I’m very pleased to finally announce KDAB’s latest R&D project to the public: hotspot – a GUI for the Linux perf profiler. I have used Linux perf a lot over the past years.
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 […]
Registrations for CppCon 2017 have just opened! CppCon is the annual conference for the C++ community: five days packed with amazing talks, inspiring keynotes, panel discussions, hallway chats, fun evening events and much more. CppCon is a project of the Standard C++ Foundation, a not-for-profit organization whose purpose is to support the C++ software developer […]
QZXing is a very useful library: It provides an easy to use Qt integration API around the barcode scanning library ZXing (zebras crossing). Because it is so easy to setup QZXing in a Qt application, we and most of our customers end up using it when they need to scan images for barcodes. There is, or rather […]
In a previous blog post we introduced clazy, a clang plugin which makes the compiler understand Qt semantics, allowing you to get compile-time warnings about Qt best practices ranging from unneeded memory allocations to misuse of API, including fix-its for automatic refactoring. Today we’ll do a round-up and present the checks related to connect statements, […]
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 […]
Bringing software into a safety critical environment can be tricky, especially when using the complex APIs needed for modern 3D graphics. That’s what makes OpenGL SC (Safety Critical) so important: it bridges the gap between beautiful displays and functional safety, while trying to remain as close to existing embedded standards that we all know and love. OpenGL SC will only […]
This blog series will introduce the clang-tidy utility from the Clang/LLVM project and show how to use it to automatically refactor
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 […]
