Struct ScaleCtrl 

pub struct ScaleCtrl { /* private fields */ }

Two-handle range slider (min/max selector).

Renders 5 paths: background, border, selected range, left handle, right handle.

Implementations

impl ScaleCtrl

pub fn new(x1: f64, y1: f64, x2: f64, y2: f64) -> Self

pub fn set_min_delta(&mut self, d: f64)

pub fn value1(&self) -> f64

pub fn value2(&self) -> f64

pub fn set_value1(&mut self, v: f64)

pub fn set_value2(&mut self, v: f64)

Trait Implementations

impl Ctrl for ScaleCtrl

fn num_paths(&self) -> u32

fn color(&self, path_id: u32) -> Rgba8

impl VertexSource for ScaleCtrl

fn rewind(&mut self, path_id: u32)

Reset the vertex source to the beginning of the given path. path_id selects which sub-path to iterate (0 for the first/only path).

fn vertex(&mut self, x: &mut f64, y: &mut f64) -> u32

Return the next vertex. Writes coordinates to x and y, returns a path command. Returns PATH_CMD_STOP when iteration is complete.
