It finally happened – a live Qt event in Berlin, with a superb training day to kick it off. This pared down event was a smashing success and has given us some great ideas for future ones.
See some more highlights below as well as our live News Report from the conference, including interviews with our Keynote speakers recorded on site. The rest of the program recordings will be published after the summer.
With huge thanks to our sponsors, particularly The Qt Company, for helping to make this joyous event happen. See you all next time!

This year’s Embedded World went surprisingly well. Most of the usual exhibitors were there and we saw a nice flow of visitors to our stand at the Qt booth in Hall 4.
Even though it wasn’t as crowded as in pre-Covid times, there was good interest in our services for Qt/QML, C++ and 3D technologies. Particularly, the two latest demos featured in the side panel drew a lot of attention: Rust Bindings for Qt and Kuesa 3D 2.0 (see more on that in the Kuesa release below).
It was good to meet again with people from the Embedded industry and get in touch with old and new partners. See our latest Embedded Trends video from partner Tuxera, below.

Fun with Paths and URLs in QML
Managing Your QML Assets with Ease
|
|
|
|
|
|
| |
|
| |
| |
|
|
| |
There are a few small, and sometimes already quite old, features in Qt that, when combined, can be a very nice way to deal with assets in your QML application — especially if some of them live on the file system, some in a resource, and some may need localization or translation. Let’s dive in!
Read on.

With Apple moving to Apple Silicon for all of their new products, software developers are having to figure out how to support both Intel and Apple Silicon devices.
Unfortunately, even if you’re not ready to move to Apple Silicon, that doesn’t necessarily exempt you from dealing with universal binaries, especially when it comes to third party dependencies.

Hotspot adds bi-directional hover highlighting
Hotspot supported the one-way highlight from the flamegraph to the event timeline, now it does it the other way round too – hovering events in the timeline will highlight the corresponding stacks in the flamegraph. Check it out!
See our Hotspot demo, as shown at Embedded World.
Hotspot is a standalone Linux GUI for performance data. Find out more and download it on Github.
