Struct qt_core::AspectRatioMode

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

This enum type defines what happens to the aspect ratio when scaling an rectangle.

C++ enum: Qt::AspectRatioMode.

C++ documentation:

This enum type defines what happens to the aspect ratio when scaling an rectangle.

See also QSize::scale() and QImage::scaled().

Implementations

impl AspectRatioMode

pub fn to_int(&self) -> c_int

impl AspectRatioMode

pub const IgnoreAspectRatio: AspectRatioMode = _

The size is scaled freely. The aspect ratio is not preserved. (C++ enum variant: IgnoreAspectRatio = 0)

pub const KeepAspectRatio: AspectRatioMode = _

The size is scaled to a rectangle as large as possible inside a given rectangle, preserving the aspect ratio. (C++ enum variant: KeepAspectRatio = 1)

pub const KeepAspectRatioByExpanding: AspectRatioMode = _

The size is scaled to a rectangle as small as possible outside a given rectangle, preserving the aspect ratio. (C++ enum variant: KeepAspectRatioByExpanding = 2)

Trait Implementations

impl Clone for AspectRatioMode

fn clone(&self) -> AspectRatioMode

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for AspectRatioMode

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

Formats the value using the given formatter.

impl From<AspectRatioMode> for c_int

fn from(value: AspectRatioMode) -> Self

Converts to this type from the input type.

impl From<i32> for AspectRatioMode

fn from(value: c_int) -> Self

Converts to this type from the input type.

impl PartialEq for AspectRatioMode

fn eq(&self, other: &AspectRatioMode) -> 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.
