Session proposals:
Add topics you would like to talk about here. We will review the proposals closer to the event to create the schedule.
| Topic | Speaker | Format | Summary |
|---|---|---|---|
| Topic Title | Add Your Name(s) | Discussion/Presentation/Workshop/Lightning talk/... | Add a short paragraph about the scope of the proposed talk. |
| Qt Bridge for Rust | Matthias Rauter | Presentation + Discussion | A short presentation of what we have in the Rust Qt Bridge. An overview over the API and the use cases we cover.
Discussion about what to improve and how to contribute and collaborate. |
| Qt & CRA | Alex Blasche | Presentation + Discussion | A presentation how CRA compliance impacts Qt development teams and contributors. |
| C++26 and moc | Volker Hilsheimer | Presentation + Discussion | After Reflections landed in gcc-trunk I followed up on my hackathon project to see how much we can implement what moc does using Reflections. This was a promising exercise, even though a few things were not quite possible yet.
Let's have a look at what - based on that experiment - the code for a meta-object enabled type in Qt could look like. |
| Tickling the boundaries of Qt Widgets Text Editing | Igor Khanin | Presentation + Discussion | A tale of my journey building a niche text editor using Qt widgets, the edges of the Qt's rich text rendering and editing APIs, and perhaps tossing some ideas of what can be improved. |
| What Qt Looks Like to an AI | Oleksandr Kunichik | Presentation + Discussion | Benchmarking AI coding agents on a real paused Qt 6/Android app. The failures map directly onto Qt design choices: MOC invisibility, QML-root signal trap, under-represented JNI API. Closes with five concrete asks for qmllint/qmlls/docs to make Qt more AI-legible. |
| Qt Canvas Painter - Status & Future | Kaj Grönholm +
Laszlo Agocs |
Presentation + Discussion | Introduce Qt Canvas Painter, the design approach and the API. Then explain how it has been built on top of the QRhi. Introduce the Canvas2D element, new in Qt 6.12. Finally, show example applications & benchmarks and discuss & plan together about the future. |
| Qt Profiler: From QML to Holistic System Performance | Cristian Adam + Marcus Tillmanns | Presentation + Discussion | Qt Profiling is evolving from a specialized QML tool into a holistic, multi-platform performance ecosystem. We will discuss our strategic moves toward native sampling (Windows, macOS, Linux), the integration of AI-driven insights via ACP/MCP, and our plan to bring high-fidelity performance data—including Quick 3D metrics and flamegraphs—directly into the developer's workflow in Qt Creator and VS Code. |
| .NET Interop: Qt Bridge for C# and beyond | Miguel Costa | Presentation + Discussion | Brief overview of the C# bridge's current status, future plans, and what it all means, not just for C# apps with Qt UIs, but also for C++ apps using .NET libraries. |
