Session Summary
The native look of UI elements have changed their appearance starting with Windows 11. Since Qt 6.7 the UI changes were incoorperated into QtWidgets with a new QWindows11Style. This presentation will give a brief introduction into the style and about recent developments with a glimpse on what comes next for Qt on Windows.
- Windows 11 Style for QtWidgets
- Custom Titlebars
- Refactoring COM to winRT
- Windows on ARM
- Transparency effects
- Windows packaging
- .Net with Qt
- Windows App SDK integration

Notes
Qt's WinUI3 style
- Qt couldn't use WinUI3 natively. => Uses XAML to generate pixmaps
- Uses more colors
- More rounded corners => relies on transparency
- We support Light and Dark mode
Future
- Custom Titlebars
- Refactor COM to winrt ?
- Bluetooth
- Support Windows on Arm (WoA)
- Support the ARM emulation layer
- transparency effects
- Add support for MSIX packaging
- Add support MS Store
- .net with Qt
- Prototype for adding Qt to a WPF application
- Windows App SDK support
- Some challenges with cmake
Various feedback
- Use accelerated APIs instead of GDI?
- Investigate synchnization of Qt and windows (to avoid potential flickering)
- API to configure default sizes of UI elements of WinUI3 (to be more touch friendly)?
- Qt Creator have several issues with using the WinUI3 style.
- Problem with alpha blending. Each widget must be created as transparent with Qt::WA_TranslucentBackground
- Check if Qt::FrameLessWindowHint is actually needed.
- The Affine Transformations Qt Widgets Example with Windows Store deployment (github.com)
