This video introduces the series, defining the typical problems of Qt Widgets applications that we are going to try and solve using GammaRay.
Qt Quick comes with a few visualizations useful for profiling its rendering performance. While these visualizations are built inside Qt Quick itself, there are a few downsides when using them directly. GammaRay makes them more accessible and useful; in this video, we are going to show you how.
As a user, there is nothing more annoying than a dialog saying "192.168.0.256 is not a valid IP address". Instead of allowing your user to type in invalid data, help them instead. There are three tools in your toolbox for that, namely input masks, validators and completers.
One of the useful outcomes the work Bertjan did on tooling for program understanding and refactoring is a list of considerations we can use to assess the suitability of new tools. Requirements for a porting system Section 1.3.5 of his thesis details the requirements for a similar porting system: GR1: Scalability The qt4to5 porting tool […]
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 […]
If you ever need to create a project around a single C++ file (or just a few C++ files) in CMake, as you might for quick test cases, you might find it tedious to write a CMakeLists.txt file by hand every time. To make this easier, I've written a script called cmake-project that you can […]
The KDE Community has been developing a variety of Free Software products using Qt for 25 years now. Among them, the Plasma Desktop Environment, creativity tools like Krita and Kdenlive, educational applications like GCompris, groupware suites like Kontact and countless other applications, utilities, and widgets. Qt is famous for its rich set of high-quality, cross-platform […]
KDAB will be Gold sponsors at this year’s free online edition of Qt World Summit on November 9th, 2022. Our very own Jesper Pedersen will present his talk “Highlights from Qt Widgets and More”. Don’t miss out! Join developers, designers, managers, and executives to get inspired by the latest developments with Qt. Register now and […]
This video is the closing session of the first Qt Desktop Days. It includes a Q&A on Qt and the Desktop with key figures from the Qt Community.
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 April 2022, we put out an April's Fools where we demonstrated the AI integration in Qt creator. Fortunately within the same year reality surpassed us, and now we are all much more productive thanks to ChatGPT. You may ask, how does it know all the stuff it knows? Well, it obviously watched Qt Widgets and More! I did, however, find that it had a few glitches, so this episode will be fixing those, but telling it about all the best practices around Qt Widgets development
This video shows how to run Clang-tidy, a static analysis tool for C/C++ code, warning its users about potential errors, performance problems or code that modern C++ allows to express in a better way. Often, clang-tidy can even apply modernizations automatically. Applying clang-tidy is not exactly intuitive, but successfully applied, it is an invaluable support in migrating large codebases to new C++ standards.
This tutorial shows how to display Qt Widget windows in a Qt Quick application, combining the flexibility of both frameworks. Learn how to manage integration through C++, expose widget properties and signals to QML, and build multi-window UIs for desktop or embedded platforms from real world examples.
Creating applications for cross-platform compatibility is a modern best practice. It increases deployment flexibility and allows applications to reach a wider audience. However, doing it properly can involve some trial and error. At KDAB, we’ve built many multiplatform desktop applications. Here, we’ve compiled a few insights from that process to help you build better software. […]
You've reached the third and final entry of the Instantiating arbitrary Qt Quick components with JSON series. Part 1 and Part 2 can be found at their respective links. The first part focuses on the software design pattern used to dynamically instantiate components. The second one shows how to layout these dynamic components by incorporating […]
KDAB was Platinum sponsor at this year's Qt World Summit on November 28th-29th Finally, the Qt World Summit was back in person at the bcc (the Berlin Congress Centre)! Those of you who have been attending former years know that KDAB usually offers a KDAB Training Day as part of the conference. This year, we […]
You may already be hosting your code on GitHub, but do you know that GitHub provides a built-in Continuous Integration solution called GitHub Actions that is very easy to set up and free for public repositories? In this article I'm providing a crash course on what GitHub Actions are and how to use it for […]
The great content from Qt Desktop Days continued on day three. QML for Desktop If you’re building a desktop application today, should you consider building the UI with Qt Quick? That’s the question that KDABian Shantanu Tushar answers in this session. He walks us through the pros and cons of Qt Widgets versus Qt Quick, […]
Clazy is a clang plugin which extends the compiler with over 50 warnings related to Qt best practices ranging from unneeded memory allocations to API misuse. It's an opensource project spawned by KDAB's R&D efforts for better C++ tooling. Today, we're proud to announce a Clazy Web UI to view all warnings emitted by Clazy, […]
A couple of months ago, Jesper Pedersen introduced our presentation tool for trainings, called SlideViewer. As SlideViewer is mainly used for our Qt and Squish trainings, we naturally have many code examples on the slides, ranging from C++ and QML to Python and XML. In this blog post, we will take a closer look at […]
