High DPI Session at Qt Contributors Summit 2019
Topics
- Icons always scaled with fractional factors in QPixmap QIcon::pixmap(QWindow *...) const qicon.cpp:899
(Milian W to report bug), fix it to always downscale
- Separate factors: Use fractional only for fonts, adapt sizes to icons?
- Tor Arne: Concerns about complexity ; Wayland and macOS have scaling built in whereas Windows/Linux require Qt handling. Move scaling code to QPlatformWindow, etc?
- David Edmundson: QML Image's sourceSize property is buggy/misleading, clarify docs at least
