Struct kas::widgets::ProgressBar

pub struct ProgressBar<D>where
    D: Directional,{ /* private fields */ }

A progress bar

The “progress” value may range from 0.0 to 1.0.

Implementations

impl<D> ProgressBar<D>where D: Directional + Default,

pub fn new() -> ProgressBar<D>

Construct a progress bar

The initial value is 0.0; use ProgressBar::with_value to override.

impl<D> ProgressBar<D>where D: Directional,

pub fn new_with_direction(direction: D) -> ProgressBar<D>

Construct a slider with the given direction

The initial value is 0.0; use ProgressBar::with_value to override.

pub fn direction(&self) -> Direction

Get the progress bar’s direction

pub fn with_value(self, value: f32) -> ProgressBar<D>

Set the initial value

pub fn value(&self) -> f32

Get the current value

pub fn set_value(&mut self, value: f32) -> Action

Set the value

Returns Action::REDRAW if a redraw is required.
