Struct qt_core::HighDpiScaleFactorRoundingPolicy

#[repr(transparent)]pub struct HighDpiScaleFactorRoundingPolicy(_);

This enum describes the possible High-DPI scale factor rounding policies, which decide how non-integer scale factors (such as Windows 150%) are handled.

C++ enum: Qt::HighDpiScaleFactorRoundingPolicy.

C++ documentation:

This enum describes the possible High-DPI scale factor rounding policies, which decide how non-integer scale factors (such as Windows 150%) are handled.

The active policy is set by calling QGuiApplication::setHighDdpiScaleFactorRoundingPolicy() before the application object is created, or by setting the QT_SCALE_FACTOR_ROUNDING_POLICY environment variable.

This enum was introduced or modified in Qt 5.14.

See also QGuiApplication::setHighDpiScaleFactorRoundingPolicy() and AA_EnableHighDpiScaling.
