Session descriptions for Saturday

Qt Installers - path forward

We're putting significant effort in our offline and online installers, and the framework that powers them. What are the biggest impediments in the current setup? Which alternative ways of distribution should we consider (3rd party package managers, online stores ..)?

Qt website and services

Tero Kojo

Status and future outlook of the services we have running for Qt project. Includes most services that are run under the qt.io domain like Forum and Wiki. Excludes codereview and bugreports, as I am not in charge of those.

Resolution independence and HighDPI support

Paul O. Tvete

Discuss how to support creation of device independent user interfaces. This includes the DEVICE_PIXEL_RATIO approach for legacy applications, and resolution independent units for Qt Quick.

Services in Qt for Android

Eskil A. Blomfeldt and Christian Strømme

Discuss how to implement support for Android Services in Qt for Android, specifically the problem of having both an Activity and a Service in the same application. Is it possible to provide the two, with independent entry points and exit points, in the same process? Or does it have to be separate processes? This session serves as brain storming and discussion about how this can be achieved and what the possible pitfalls are.

Qt on Embedded Linux

Laszlo Agocs

Discuss the state of Qt 5.5 on Embedded Linux, focusing on recent additions and future plans for graphics and input. Wayland & Qt Compositor work can also be discussed.

Qt and 3D

Pasi Keränen

Discuss the state of 3D enablers in Qt now that 5.5 brings Canvas3D (a WebGL-like API to QtQuick) and Qt 3D 2.0 technology preview (an upcoming advanced, fully data driven C++ 3D scene graph). Some things we probably should discuss include: How easy is it to use these? Performance expectations? What kind of tooling would be in the scope of Qt to offer a good enough end-to-end content pipeline? What kind of use cases should we be looking at and optimising for?

Local Qt Meetups, how to get them going and what support is needed?

Tero Kojo

Qt used to have many more local groups doing meetups in the past. What needs to happen to get them going again? What kind of support is needed and what how can we help local Qt user groups?

Next-generation pointing device and gesture support in Qt Quick

Shawn Rutledge

Because the Areas (MouseArea, PinchArea, Flickable etc.) have proven so unwieldy and we have so much trouble to support proper multi-point touch in a backwards-compatible way with them, an idea has materialized to use handlers in the form of attached properties instead, similar to the Keys attached property for handling key events. It's not a very solid plan yet though, so this is a good idea to discuss both that idea and any alternatives that anyone would like to suggest, to make event handling clean, simple and flexible.

Continuous Integration

Frederik Gladhorn

Changes in our infrastructure to make integrations pass more reliably. Let's discuss how we're changing the testing infrastructure and how it hopefully leads to more reliable test integration and also package creation.

Dynamic applications with QmlViewer as visualization portal

Sem Donkers

This topic tries to touch on fundamental issues with current UI design : creeping featuritis. The objective is to discuss enhanced UI design principles and QML/Qt's role therein. More concretely we would like to position QmlViewer as the ultimate feature portal, rendering the display needs of features pulled in by user needs or transient circumstances.

DynamicQML : Accessing any foreign technology within QML

Sem Donkers

We present a novice module, Organic Assembly (OA), that gives QML access to qobjects without ever using 'moc'. OA uses inspection to access features in any supported technology and creates qobjects on the fly. Thus QML can access things like d-bus, remote services using RPC, (D)COM, Soap, AI (and other) languages. Access to technologies is provided just-in-time. Adding a new technology is a one time effort. We would like to discuss the abilities and future of this module and invite the integration of other technologies.

Video filtering, GPU compute (OpenCL, CUDA) and computer vision (OpenVX, OpenCV)

Laszlo Agocs

Discuss recent new features like video filters ( http://blog.qt.io/blog/2015/03/20/introducing-video-filters-in-qt-multimedia/ ), research like Qt QuickCL ( https://blog.qt.io/blog/2015/04/20/qt-quick-with-the-power-of-opencl-on-embedded-linux-devices/ ) and the Jetson TK1 experiments ( http://blog.qt.io/blog/2015/03/03/qt-weekly-28-qt-and-cuda-on-the-jetson-tk1/ ) and do some brainstorming to come up with ideas to try in the future in this domain.
