Latest revision as of 09:22, 10 June 2022

An appeal to record as many sessions as possible The Technical Product Management team in The Qt Company kindly asks to record as many sessions as possible. Unfortunately, there is a two-day workshop with another team on exactly the same days and no one from PM will be able to attend the live presentations. Last year, there were hesitations regarding recording. Please make it possible this year. If required recodings will be for internal use and will never be published for public access, and or if you decide so we can publish too.

Topic Speaker Format Comments
Example: How Can We Improve xxx? J Doe Discussion We currently struggle with YYY and we want to find solutions for it.

We should come up with an action plan.

Qt Infrastructure for CI Tony Sarajärvi Presentation/Discussion A presentation where the hardware side of the CI is presented along with monitoring of the system
Licenses in Source Code Jörg Bornemann Presentation / Discussion (30 min) Announcing SPDX changes, discussing next steps (qt_attribution.json file format)?
Ghost Maintainers Andy Nichols, Paul Tvete, Eddy Discussion There are Qt modules that have maintainers who are largely absent, yet we have no formal process for handling this situation; and Maintainers != Gerrit's list.
How to create a great Qt tutorial video H Humaljoki (facilitator) Workshop At the end of the workshop, we would have gathered best practices on how to create great video tutorials about Qt. The participants would know where to start in creating their own learning content.
What's new in QML (non-visual) tooling QML team Presentation/ Discussion Learn about upcoming features in qmllint and the QML language server, and make feature requests/suggestions
Coroutines in QtCore Giuseppe D'Angelo In-depth technical Discussion We have at several in-flight patches trying to add Coroutines to QtCore.

I'd like a very long (ideally multi-slot) session to discuss and experiment with the API of such a thing, including

  • adding coroutines support for QFuture ("heavy")
  • coroutines directly to signals/slots ("not so heavy")
  • coroutines + QThreadPool support
  • misc.
QtScrypt Cristián Maureira-Fredes Presentation/

Discussion

Some time ago, I wrote a hackathon project to enable Python scripting within C++ applications - the outcome was cool :). Due to the similarities, I decided to call it QtScrypt, because it kind of follows a similar idea as QtScript, but with Python.

I would like to present the proof of concept I have, and if it's interest from someone else to start the development and create a proper project out of this idea.

qt-project.org Cristián Maureira-Fredes Presentation/

Discussion

I had many ideas on how to improve our project website, but didn't manage to implement them. I'd like to present the current version of the code that generates our portal, the plots, and everything, mainly to look for people that will be willing to help improving the site! This is a good idea for first-time contributors to jump into a simple project where there is a lot to improve ;)
The Qt Community Pedro Bessa Presentation/

Discussion

As Qt's Community Manager, I plan to (re)introduce my role, my own approach and the plans to push the Community further.
  • What does the Community Manager do?
  • The Current State of the Qt Community
  • The Qt Community Roadmap: Our Plan Forward
C++20 in Qt Fabian Kosmale, Marc Mutz Discussion We already had some discussion about usage of C++20 types in our ABI (see https://lists.qt-project.org/pipermail/development/2022-January/042151.html). However, there are still further things that we should discuss:
  • Are there non-ABI impacting changes that we should do? E.g. marking classes as views/ranges, supporting new std types where necessary, etc.
  • How should our testing story look like for C++20? Currently, we only have one gcc build for C++20 in our CI
  • Do we want to mandate C++20 during the lifetime of Qt 6 at some point? Can we (think of embedded platforms)?
  • C++ modules and CMake? How will it impact us?
Qt for Python Discussion Friedemann Kleint Discussion Discussion about future development in Qt for Python/Shiboken
Qt Design Studio: How to contribute Thomas Hartmann Presentation/

Discussion (30 min)

What is Qt Design Studio and how can developers contribute to the code base
Conan - a package manager for Qt? Kai Köhne Presentation/

Discussion (30 min)

State of the endeavour, discussion about future
Qt Quick Effect Maker Kaj Grönholm Presentation/

Discussion (30 min)

Introduction to Qt Quick Effect Maker (QQEM), a work-in-progress tool to boost productivity for creating custom Qt Quick shader effects. Some history about Qt Graphical Effects, MultiEffect etc. compared to QQEM and a live demo!
Qt Wayland state Aleix Pol Break-out session (not in main room)

(30 min)

State of the issues, changes and challenges. Regular check-in with Qt/KDE. Anyone is welcome, but content is operational (reviewing patches, discussing bug reports, etc.)
Directions for QTestLib messages Marc Mutz Discussion

(30 min)

Should QSKIP, QVERIFY2, etc. become printf-style to avoid formatting (asprintf(), arg()) entirely, or should they have QAnyStringView arguments to avoid all the toLocal8Bit().constData()? Can we have both?
QtPDF Shawn Rutledge Presentation/

Discussion

Quick overview of what has been done (a bit more since https://youtu.be/y6-Khqrrz_U), and discussion of what could be done if the community is interested in helping (annotations, XFA, ??) Future of QtPDF vs. poppler: let's emphasize that we don't necessarily want to displace poppler in the open-source world, but I wonder if there is a chance for synergy, by harmonizing APIs (QTBUG-77517). Perhaps can discuss the future of rendering if there's time (what if https://youtu.be/JTjJpXd7zNc had turned out a bit better: we could render PDF sub-elements directly in the SG).
Color space in Qt - issues and possibilities Allan Sandfeld Jensen Presentation/Discussion

(30 min)

Quick overview of what the problem is with color space, gamma correction, WGC and HDR in painting. What users can currently do about in Qt, and a discussion about what we could do in the future with existing or new API.
