Not all Qt developers are using Qt Creator as their main IDE for development. Some of us are using other IDEs, like Visual Studio, Visual Studio Code or CLion, per choice or because a project requires it. On Windows, with the MSVC compiler, the debugging experience with Qt 6 can be quite frustrating for some […]

The agenda is published and KDAB engineers are offering a wealth of technical talks this year. Optimizing the Rendering of Qt Quick 2 applications, Giuseppe D'Angelo If you have ever wondered how Qt Quick applications are rendered to the screen, and how to use that knowledge to find and fix performance problems, then this talk […]

Back in February we wrote about our work to add 'MacOs touch bar' support to Qt. Between then and now, support has been added in QtCreator: However, the changes have not been integrated upstream in Qt, which means there is still no easy way to add support to your own applications. KDAB is happy to […]

A couple of weeks ago, we guided you through setting up a chat application and server in our first blog of this series. This is the second and final blog of this Qt Allstack series. Firebase Messaging Now that we have a functional chat application, it’s time to add real world features, like push notifications. […]

AKA: I know what you did last Christmas ! Hello folks, I'd like to share with you a few things that I did during this Xmas. Besides the fact I'll never ever take a vacation before Xmas, because Brasov is a tourist attraction and it was FULL of tourists in that period. I could ski […]

Introduction This article is part of a blog series about Clang Tidy. In the previous article we learned about the general usage of Clang Tidy to automatically refactor source code for projects using the CMake build system. In this particular episode we'll discuss using Clang Tooling on projects using different build systems with the help […]

Last week I visited a new customer who is making medical and industrial devices which have one thing in common: image and video capturing, and letting the user save these files onto a USB key. These devices run embedded Linux and the application is done in Qt (and gstreamer for the video capture). The new […]

Here's the full list of changes: Experimental […]

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 […]

In our earlier blog, The Smarter Way to Rust, we discuss why a blend of C++ and Rust is sometimes the best solution to building robust applications. But when you’re merging these two languages, it’s critical to keep in mind that the transition from C++ to Rust isn’t about syntax, it’s about philosophy. Adapting to […]

In a previous blog we demonstrated the most straightforward method to optimize Visual Studio Code for a Qt / C++ environment: simply let the tools do all the work! The example GitHub project we discussed automatically installs both the Microsoft C/C++ and clangd extensions into VS Code. You might wonder why you need both C++ […]

Memory bugs are tricky. Leaks have a clear impact on performance, and quickly become hard to spot when heap allocated objects move too much. Memory access bugs, on the other hand, make your program crash right away, if you're lucky. In less desirable cases, they may end up corrupting random objects on the heap, and […]

Have you ever noticed code highlighting disappearing in Qt Creator for some projects, without any apparent reason? Can't get Ctrl+Click to work on any class name or function name anymore? Maybe you have ignored it at first, got used to it, and decided it's just one of those things that just "happen sometimes"; or maybe […]
