Struct qt_core::HighDpiScaleFactorRoundingPolicy

pub struct HighDpiScaleFactorRoundingPolicy(/* private fields */);

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.

Implementations

Trait Implementations

impl Clone for HighDpiScaleFactorRoundingPolicy

fn clone(&self) -> HighDpiScaleFactorRoundingPolicy

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for HighDpiScaleFactorRoundingPolicy

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl From<HighDpiScaleFactorRoundingPolicy> for c_int

fn from(value: HighDpiScaleFactorRoundingPolicy) -> Self

Converts to this type from the input type.

impl From<i32> for HighDpiScaleFactorRoundingPolicy

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for HighDpiScaleFactorRoundingPolicy

fn eq(&self, other: &HighDpiScaleFactorRoundingPolicy) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
