Struct qt_core::AspectRatioMode

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

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().

Methods

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)
