Struct SliderCtrl 

pub struct SliderCtrl { /* private fields */ }

Horizontal slider control rendered via AGG.

Renders 6 paths: background, triangle indicator, label text, pointer preview, active pointer, and step markers.

Port of C++ slider_ctrl_impl.

Implementations

impl SliderCtrl

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

pub fn label(&mut self, fmt: &str)

Set the label format string. Use %3.2f as placeholder for the value.

pub fn range(&mut self, min: f64, max: f64)

Set the value range.

pub fn value(&self) -> f64

Get the current value (in user range).

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

Set the current value (in user range).

pub fn num_steps(&mut self, n: u32)

Set the number of discrete steps (0 = continuous).

pub fn set_descending(&mut self, d: bool)

pub fn border_width(&mut self, t: f64, extra: f64)

pub fn text_thickness(&mut self, t: f64)

Trait Implementations

impl Ctrl for SliderCtrl

fn num_paths(&self) -> u32

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

impl VertexSource for SliderCtrl

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.
