Struct Scrub 

pub struct Scrub { /* private fields */ }

A seek bar held by the pointer or a finger, for a surface that paints its own controls and routes its own input (the shell’s cards). The host hands in the face it paints, so the press, the drag and the paint read one geometry.

Implementations

impl Scrub

pub fn press(&mut self, face: &SliderFace, point: Point) -> f64

A press on the bar at point: the knob jumps there and is held.

pub fn drag(&mut self, face: &SliderFace, point: Point) -> Option<f64>

The held knob follows point; None while nothing is held.

pub fn release(&mut self) -> Option<f64>

Let go: the fraction to seek to, once.

pub fn cancel(&mut self)

Drop the hold without seeking (the surface closed under it).

pub fn held(&self) -> Option<f64>

pub fn shown(&self, playing: f64) -> f64

Where the knob stands: under the hand while held, else at playing.

Trait Implementations

impl Clone for Scrub

fn clone(&self) -> Scrub

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Scrub

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

Formats the value using the given formatter.

impl Default for Scrub

fn default() -> Scrub

Returns the “default value” for a type.

impl PartialEq for Scrub

fn eq(&self, other: &Scrub) -> 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.
