Sessions
Qt Marketplace
Tino Pyssysalo and Marko Finnig
Qt Marketplace status, existing and planned features, launch schedule, content publishing process, and content usage.
Qt 6 Graphics Overview
Laszlo & co.
Let's have an overview of graphics related changes in Qt 6. The keynote will probably mention some of these, the goal in this session is to expand on them a bit. There can then be deeper individual discussions on specific topics during the next two days, if there is interest.
C++17 language and std library features for Qt 6
Volker Hilsheimer
With Qt 6 we want to be able to use some C++ 17 language and std library features. Not all compilers and platforms we are going to care about by the time Qt 6 comes around will support evertyhing, so this needs a balanced discussion of up- and down-sides, leading to a pragmatic subset that we can rely on. See https://bugreports.qt.io/browse/QTBUG-77477 for details.
Code Review: Sharing the load
Sometimes we wait and wait for anyone to review our changes. Sometimes we struggle to keep up with all the reviews we're asked to look at. How can we organise this so that no-one waits too long but all of us still have time to hack on code ? Time To Be Arranged.
API Review Process
Volker Hilsheimer
As experienced during Qt 5.13 and Qt 5.14 releases, some changes to APIs were getting feedback only very late in the release process, when the header diff was uploaded for sanity review. This seems a bit late. I'd like to see if we can find a more effective way of integrating API reviews into the general code review process. Perhaps changes that change public headers require a slightly different process than fixes and changes that touch only the implementation.
Evolving the Qt Project Security Policy
Volker Hilsheimer
During summer, the Qt Project Security Policy was moved from a wiki page into QUIP-15, and during that review process, some changes and additions were proposed to strengthen the project's capability to respond to security issues. Those changes were not taken into the QUIP as part of the move, since for the moment we only wanted to move the content. Suggestions included a clearer statement how security fixes are applied to LTS releases; the integration of CVE handling when disclosing vulnerabilities; the documentation of processes established by the Qt Company; and a general review of the way the "core team of developers" is organized, and operating.
Discussing these (and additional) proposals, and agreeing on what should become part of the policy (and thus the responsibility of the Qt project) is the purpose of this session. A proposal is available here: https://codereview.qt-project.org/c/meta/quips/+/278819
Qt for Python and beyond
Cristián Maureira-Fredes
After one year since the official release of Qt for Python we have been getting many new ideas for features to include in the next releases. Most of the features are explained in the latest blog post we wrote, but nevertheless we should try to build the next versions in favor of the Qt ecosystem, this means not only improving the Qt for Python project, but more like answering the question "How Qt for Python can improve the Qt project?". Please join us in this session to discuss how we can make Qt for Python a first-class citizen in the project by giving it more responsibility.
Improve the contributor experience of the Qt project
Cristián Maureira-Fredes
After the following steps:
- Creating Qt account,
- Creating Gerrit account,
- Agreeing with the CLA,
- Configure gerrit locally.
You are ready to start contributing.
If you think that it is too much, you should join this discussion. We aim to focus on having a welcoming and easy-to-do process for getting more people involved in contributing to Qt. Check the related task on JIRA
Platform-specific APIs in Qt 6
Tor-Arne Vestbø, Johan Helsing, Paul Olav Tvete
There are currently multiple different ways of exposing platform-specific APIs in Qt (Qt Platform Headers, Qt Platform Native Interface, Qt Platform Support, and Qt Foo Extras among others). Qt 6 is a good time to take a look at how this can be improved and coordinated better.
Refurbishing Qt Widgets internals
Tor-Arne Vestbø, Johan Helsing, Paul Olav Tvete
This is a session to discuss changes to the underlying architecture in Qt Widgets, such as the backing store and parent/child hierarchy.
Qt Wayland Client and extensions
Johan Helsing, Paul Olav Tvete
What existing extensions should we support, and should we propose any new extensions for wayland-protocols? What functionality is missing from Qt Wayland Client, and how can we improve cooperation with KDE and other stakeholders? (note that there is a separate session about the general approach to platform-specific APIs in future Qt versions.)
