Qt World Summit 2025

These past two days I attended the Qt World Summit 2025

It happened in Munich in the SHOWPALAST MÜNCHEN. The venue is HUGE,  we had around 800 attendees (unofficial sources, don't trust the number too much) and it felt it could hold more. One slightly unfortunate thing is that it was a bit cold (temperatures in Munich these two days were well below the average for May) and quite some parts of the venue are outdoors, but you can't control the weather, so not much to "fix" here.

 

The venue is somewhat strangely focused on horses, but that's nothing more than an interesting quirk.

Qt World Summit is an event for the Qt developers around the world and the talks range from showcases of Qt in different products, to technical talks about how to improve performance along others less Qt centric talks about how to collaborate with other developers or about "modern C++".

As KDE we participated in the event with a stand trying to explain people what we do (David Redondo and Nicolas Fella were more in the stand than me, kudos to them)

For following years we may need to re-think a bit better our story for this event since I feel that "we do a Linux desktop and Free Software applications using Qt" is not really what Qt developers really care about, we maybe should focus more on "You can learn Qt in KDE, join us!" and "We have lots Free [Software] Qt libraries you can use!".

 

Talks for the videos will be published "soon" (or so I've been told). When that happens the ones I recommend you to watch are "Navigating Code Collaboration" by  LAURA SAVINO, "QML Bindings in Qt6" by ULF HERMANN and "C++ as a 21st Century Language" by BJARNE STROUSTRUP, but the agenda was packed with talks so make sure to check the videos since probably your tastes and mine don't 100% align.

 

All in all it was a great event, it is good to see that Qt is doing well since we use it for the base of almost everything we do in KDE. Thanks to The Qt Company and the rest of the sponsors for organizing it.
