Struct Shadow

pub struct Shadow {
    pub offset: Vec2,
    pub blur: f32,
    pub spread: f32,
    pub color: Color32,
}

The color and fuzziness of a fuzzy shape.

Can be used for a rectangular shadow with a soft penumbra.

Very similar to a box-shadow in CSS.

Fields

offset: Vec2

Move the shadow by this much.

For instance, a value of [1.0, 2.0] will move the shadow 1 point to the right and 2 points down, causing a drop-shadow effect.

blur: f32

The width of the blur, i.e. the width of the fuzzy penumbra.

A value of 0.0 means a sharp shadow.

spread: f32

Expand the shadow in all directions by this much.

color: Color32

Color of the opaque center of the shadow.

Implementations

impl Shadow

pub const NONE: Shadow = _

No shadow at all.

pub fn as_shape(&self, rect: Rect, rounding: impl Into<Rounding>) -> RectShape

The argument is the rectangle of the shadow caster.

pub fn margin(&self) -> Margin

How much larger than the parent rect are we in each direction?

Trait Implementations

impl Clone for Shadow

fn clone(&self) -> Shadow

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Shadow

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

Formats the value using the given formatter.

impl Default for Shadow

fn default() -> Shadow

Returns the “default value” for a type.

impl<'de> Deserialize<'de> for Shadow

fn deserialize<__D>( __deserializer: __D, ) -> Result<Shadow, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Shadow

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

Tests for self and other values to be equal, and is used by ==.

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

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

impl Serialize for Shadow

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Widget for &mut Shadow

fn ui(self, ui: &mut Ui) -> Response

Allocate space, interact, paint, and return a Response.

impl Copy for Shadow

impl StructuralPartialEq for Shadow
