Struct SliderFace 

pub struct SliderFace { /* private fields */ }

An immediate-mode slider face: everything Slider::paint needs to draw one, with no widget instance and no CRDT binding.

A canvas app that owns its own hit-testing (a timeline inspector, a mixer strip) cannot mount a retained Slider per control — it has no Taffy node for them, and it needs a whole drag to land as one undo boundary. It can still share the look, which is what this is for. Mirrors Button::paint and ToggleGroup::paint.

Implementations

impl SliderFace

pub fn new(rect: Rect, value: f64) -> SliderFace

A face over rect showing value (clamped to 0..=1).

pub fn hovered(self, v: bool) -> SliderFace

pub fn dragging(self, v: bool) -> SliderFace

pub fn focused(self, v: bool) -> SliderFace

pub fn disabled(self, v: bool) -> SliderFace

pub fn hit_rect(&self, theme: &Theme) -> Rect

Where a pointer takes this slider: the track and the knob overhanging its ends, grown to the minimum pointer target.

pub fn overhang() -> f64

How far the knob reaches past the track’s ends (its pressed radius): a host keeps this much room either side of a slider’s rect.

pub fn value_at(&self, point: Point) -> f64

The share of the range (0..=1) under point, clamped at both ends.

pub fn track_rect(&self) -> Rect

The track rect this face paints, so a caller hit-tests the geometry it actually draws.
