Struct cursive_core::views::SliderView

pub struct SliderView { /* private fields */ }

A horizontal or vertical slider.

Examples

use cursive_core::views::{Dialog, SliderView};

let slider_view = SliderView::horizontal(10)
    .on_change(|s, n| {
        if n == 5 {
            s.add_layer(Dialog::info("5! Pick 5!"));
        }
    })
    .on_enter(|s, n| match n {
        5 => s.add_layer(Dialog::info("You did it!")),
        n => s.add_layer(Dialog::info(format!("Why {}? Why not 5?", n))),
    });

Implementations

impl SliderView

pub fn new(orientation: Orientation, max_value: usize) -> Self

Creates a new SliderView in the given orientation.

The view will have a fixed length of max_value, with one tick per block.

The actual range of values for this slider is [0, max_value - 1].

pub fn vertical(max_value: usize) -> Self

Creates a new vertical SliderView.

pub fn horizontal(max_value: usize) -> Self

Creates a new horizontal SliderView.

pub fn set_value(&mut self, value: usize) -> EventResult

Sets the current value.

Returns an event result with a possible callback, if on_change was set..

pub fn value(self, value: usize) -> Self

Sets the current value.

Chainable variant.

pub fn get_value(&self) -> usize

Gets the current value.

pub fn get_max_value(&self) -> usize

Gets the max value.

pub fn on_change<F>(self, callback: F) -> Selfwhere
    F: Fn(&mut Cursive, usize) + 'static,

Sets a callback to be called when the slider is moved.

pub fn on_enter<F>(self, callback: F) -> Selfwhere
    F: Fn(&mut Cursive, usize) + 'static,

Sets a callback to be called when the key is pressed.

Trait Implementations

impl View for SliderView

fn draw(&self, printer: &Printer<'_, '_>)

Draws the view with the given printer (includes bounds) and focus.

fn required_size(&mut self, _: Vec2) -> Vec2

Returns the minimum size the view requires with the given restrictions.

fn on_event(&mut self, event: Event) -> EventResult

Called when an event is received (key press, mouse event, …).

fn take_focus(&mut self, _: Direction) -> Result<EventResult, CannotFocus>

Attempt to give this view the focus.

fn layout(&mut self, _: Vec2)

Called once the size for this view has been decided.

fn needs_relayout(&self) -> bool

Should return true if the view content changed since the last call to layout().

fn call_on_any<'a>(&mut self, _: &Selector<'_>, _: AnyCb<'a>)

Runs a closure on the view identified by the given selector.

fn focus_view(&mut self, _: &Selector<'_>) -> Result<EventResult, ViewNotFound>

Moves the focus to the view identified by the given selector.

fn important_area(&self, view_size: Vec2) -> Rect

What part of the view is important and should be visible?

fn type_name(&self) -> &'static str

Returns the type of this view.
