Struct zng::color::LightDark

pub struct LightDark {
    pub dark: Rgba,
    pub light: Rgba,
}

Represents a dark and light color.

Note that this struct converts IntoVar<Rgba> with a contextual var that selects the color, so you can just set color properties directly with a color pair.

Fields

dark: Rgba

Color used when ColorScheme::Dark.

light: Rgba

Color used when ColorScheme::Light.

Implementations

impl LightDark

pub fn new(light: impl Into<Rgba>, dark: impl Into<Rgba>) -> LightDark

New from light, dark colors.

pub fn shade_fct(self, factor: impl Into<Factor>) -> LightDark

Overlay WHITE/BLACK to the dark/light color depending on the factor, negative factor inverts overlay.

pub fn shade(self, shade: i8) -> LightDark

Shade at 8% increments.

Common usage: 1=hovered, 2=pressed.

pub fn rgba(self) -> ContextualizedVar<Rgba>

Gets a contextual Rgba var that selects the color for the context scheme.

Also see LightDarkVarExt for mapping from vars.

pub fn rgba_map<T>( self, map: impl FnMut(Rgba) -> T + Send + 'static, ) -> impl Var<T>

where T: VarValue,

Gets a contextual Rgba var that selects the color for the context scheme and map it.

pub fn rgba_into<T>(self) -> impl Var<T>

where T: VarValue + From<Rgba>,

Gets a contextual Rgba var that selects the color for the context scheme and converts it to T.
