Struct TrackStyle 

pub struct TrackStyle {
    pub checked_bg: Color,
    pub unchecked_bg: Color,
    pub disabled_bg: Option<Color>,
}

The full track palette of a <toggle> or <switch>, resolved at spawn from markup / CSS and refreshed by the restyle pass. sync_track_fill is the only thing that reads it, and TrackStyle::fill_for is the only place a state maps to a color.

Both controls share one component because they share one skin family: they differ in shape and in how the knob moves, not in what the track is painted with.

Fields

checked_bg: Color

Track fill while checked (:checked { bg: ... } or the default accent).

unchecked_bg: Color

Track fill while unchecked (author bg or the default gray).

disabled_bg: Option<Color>

Track fill while disabled (:disabled { bg: ... }), when a rule supplied one. None leaves a disabled track on its checked/unchecked fill, which the generic disabled-opacity dim then covers.

Implementations

impl TrackStyle

pub fn fill_for(&self, checked: bool, disabled: bool) -> Color

The fill this track paints in the given state.

Disabled outranks checked: the skins order :disabled after :checked, so in a browser the later rule would win, and a control nobody can operate should not advertise its state as live.

Trait Implementations

impl Clone for TrackStyle

fn clone(&self) -> TrackStyle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Component for TrackStyle

where Self: Send + Sync + 'static,

Required Components: StyleOverrides.

A component’s Required Components are inserted whenever it is inserted. Note that this will also insert the required components of the required components, recursively, in depth-first order.

const STORAGE_TYPE: StorageType = bevy_ecs::component::StorageType::Table

A constant indicating the storage type used for this component.

type Mutability = Mutable

A marker type to assist Bevy with determining if this component is mutable, or immutable. Mutable components will have [Component<Mutability = Mutable>], while immutable components will instead have [Component<Mutability = Immutable>].

fn register_required_components( _requiree: ComponentId, required_components: &mut RequiredComponentsRegistrator<'_, '_>, )

Registers required components.

fn clone_behavior() -> ComponentCloneBehavior

Called when registering this component, allowing to override clone function (or disable cloning altogether) for this component.

fn relationship_accessor() -> Option<ComponentRelationshipAccessor<Self>>

Returns [ComponentRelationshipAccessor] required for working with relationships in dynamic contexts.

fn on_add() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_add [ComponentHook] for this [Component] if one is defined.

fn on_insert() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_insert [ComponentHook] for this [Component] if one is defined.

fn on_discard() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_discard [ComponentHook] for this [Component] if one is defined.

fn on_remove() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_remove [ComponentHook] for this [Component] if one is defined.

fn on_despawn() -> Option<for<'w> fn(DeferredWorld<'w>, HookContext)>

Gets the on_despawn [ComponentHook] for this [Component] if one is defined.

fn map_entities<E>(_this: &mut Self, _mapper: &mut E)

where E: EntityMapper,

Maps the entities on this component using the given [EntityMapper]. This is used to remap entities in contexts like scenes and entity cloning. When deriving [Component], this is populated by annotating fields containing entities with #[entities]

impl Debug for TrackStyle

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

Formats the value using the given formatter.

impl Default for TrackStyle

fn default() -> Self

Returns the “default value” for a type.

impl PartialEq for TrackStyle

fn eq(&self, other: &TrackStyle) -> 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 StyleOwner for TrackStyle

const RANK: u8 = 20

Where the owner’s values sit: a higher rank lays over a lower one.

impl Copy for TrackStyle

impl StructuralPartialEq for TrackStyle
