Due to Covid-19, the KDAB office in Berlin feels really empty. Some times, it's just me, working on hardware, and a few other guys dotted around. The office staff are all working from home. The Problem: My office is very far away from the door, yet, from time to time, KDAB gets deliveries and, as […]

The upcoming version of the C++ Standard (C++2a) is proposing to deprecate certain usages of the volatile keyword, by adopting the P1152 proposal (Deprecating volatile). Despite the somewhat "flamboyant" title, the actual deprecated parts are very limited and indeed the paper limits the deprecation to somehow language/library corner cases and/or dangerous antipatterns. For instance certain […]

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 […]

Each month KDAB schedules time for me to maintain the Qt for Android port. Usually I use it to review the pending patches or fix bugs, but sometimes there is a quiet month and I have time to add new functionalities or improve the existing ones. April was quite quiet so I decided to rewrite […]

During the last couple of months KDAB engineers have been working on improving CUPS printing support for Linux in Qt. This work has been sponsored by the LiMux project, a big thank you to them for allowing us to spend time improving Qt :). We started in early December with a series of small commits […]

With the introduction of the Qt Quick software renderer it became possible to use Qt Quick on devices without a GPU. We investigated how viable this option is on a lower end device, particularly the NXP i.MX6 ULL. It turns out that with some (partially not yet integrated) patches developed by KDAB and The Qt […]

Back in November, Apple released the latest generation of it's Apple TV product. Besides the slightly improved hardware, the true new feature is the OS which is now officially based on iOS and comes with the dedicated SDK and App Store! So we started investigating what it would take to port Qt to tvOS and […]

In this projection demo a laptop takes care of communicating with the Android smartphone on one hand, and of displaying a QtQuick application which puts together all the information for projecting on the other hand. The information being displayed includes missed phone calls, emails, calendar, time, weather, etc. This information is retrieved on the Android […]

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 […]

Touchscreens and modern user interfaces are migrating into every type of medical machine: ultrasound, infusion, CAT, MRI, x-ray, care monitors, surgery displays, information tablets, and even patient self-service systems. Touchscreens are also helping with hygiene requirements as they are liquid-proof and easily disinfected because the display is in a sealed enclosure. Qt is an ideal […]
