In the previous videos of this module we have learned how signals and slots work. We have also learned how to connect an existing signal to an existing slot (in all its variations). In this episode, we will build up on that knowledge and discuss how to declare and implement custom signals and slots – and why we would want to do that!
Software has become a critical factor of our economy. Manufacturing companies must start to think and act software-centric to survive. In this interview, software pioneer Matthias Kalle Dalheimer explains why conventional companies run the risk of becoming commoditized and how they can get ahead of the competition. What are the corner stones of a real […]
In this edition: Qt 6 release, new versions of Qt Creator and Qt Design Studio, and an outlook for 2021 interview with Kalle Dalheimer (President and CEO KDAB) covering a year in review, smart security, energy efficient software, industry demand, UI frameworks, and KDAB hiring. Also features Library of the Month: QtKeychain.
Software has become critical to our economy. Manufacturing companies must adopt software-centric thinking to survive. Software pioneer Matthias Kalle Dalheimer explains why conventional companies risk commoditization and how to stay competitive. What are the cornerstones of a real software strategy? What can traditional industries learn from software companies?
This is the third and last installment of our series about full stack tracing. If you haven’t read them yet, you’ll probably want to check out the introduction and tool setup portions first. In this blog, we’re going to focus on visualizing and interpreting full stack traces. At this point, we’re going to assume that […]
Wrapping up Qt Desktop Days, are two final sessions that cap off five days of great sessions. Kirigami: convergence with Desktop as first-class Let’s say you want to develop a mobile-looking UI... hey, wait a minute! Aren’t we talking about Qt Desktop Days? Indeed we are, but as Marco Martin, a KDE employee who works […]
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 […]
Sometimes views need more data than what's displayed in a cell. Examples include context menus for employee cells (where only the name shows) or annotation symbols for annotated data. While views could call the model directly, this breaks with proxy models in between.
With Qt 6 well on its way, it's about time we go over some of the internal changes and optimizations made to Qt 3D for the upcoming release. In a separate article, my colleague Mike Krus has already highlighted the API changes we've made in Qt 3D for Qt 6. This post will dive into […]
In this edition: Introduction, Qt 3D in Qt 6 interview with Mike Krus (Senior Software Developer at KDAB), Dashboard UI of new unu scooter, Minecraft's improved CMake build system, and Library of the month.
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.
Wait, there’s more? Yes, indeed. Qt Desktop Days delivered a lot of great content we’ve just got to share. VLC and Qt, a history If you need to play the widest variety of audio, video, or streaming formats on the planet, you probably know about VLC (the “cone player”). But did you know that VLC […]
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, […]
Kirigami is a framework built on top of QML and QtControls2. It aims to make it easier for applications to implement a modern design language for both desktop and mobile systems, providing features that base QML and QtQuickControls don’t have.
This video explains how to install and use the SpellChecker plugin for Qt Creator, a third-party contribution. GUI applications contain many user-visible strings, so shipping software with spelling mistakes would be embarrassing. While word processors have long included spell checking, programming editors traditionally lacked this feature - until now!
This talk highlights pitfalls and solutions when migrating QWidget desktop applications to Qt Quick, using MuseScore's transition as an example. We'll cover challenges in modernizing 2000s-era designs, effective QWidget-to-QML migration strategies, limitations of mixing both systems, and approaches to overcome or avoid these issues.
Qt 6 is nearly upon us. While this has not been addressed by other publications, Qt 3D is also introducing a number of changes with this major release. This includes changes in the public API that will bring a number of new features and many internal changes to improve performance and leverage new, low-level […]
What sessions were on the second day of Qt Desktop Days? Lots! QGIS loves Qt! The first session on day 2 was from Nyall Dawson who works for North Road but who is also a significant contributor to QGIS, the largest open-source GIS program in the world. Nyall explains why Qt is an awesome fit […]
Aggressive testing can ensure quality, but "test more" strategies risk redundancy and missed critical code areas—potentially life-threatening if unmanaged. A "test smarter" approach using code coverage analysis is better. This talk introduces Coco, froglogic's cross-platform code coverage tool for Qt, QML, and C/C++/C# applications, showing how to determine test coverage, identify needed tests, and track changes over time.
If you missed Qt Desktop Days, you might be wondering what you missed. No need to worry! We’re going to give you a day-by-day summary of some of the cool things that were discussed, demoed, and explained. (We’re uploading all of the videos to our YouTube channel, but we’ll provide the direct links to each […]
