Struct cosmic::iced_widget::vertical_slider::VerticalSlider

source ·
pub struct VerticalSlider<'a, T, Message, Theme = Theme>
where Theme: Catalog,
{ /* private fields */ }
Expand description

An vertical bar and a handle that selects a single value from a range of values.

A VerticalSlider will try to fill the vertical space of its container.

The VerticalSlider range of numeric values is generic and its step size defaults to 1 unit.

§Example

use iced::widget::vertical_slider;

struct State {
   value: f32,
}

#[derive(Debug, Clone)]
enum Message {
    ValueChanged(f32),
}

fn view(state: &State) -> Element<'_, Message> {
    vertical_slider(0.0..=100.0, state.value, Message::ValueChanged).into()
}

fn update(state: &mut State, message: Message) {
    match message {
        Message::ValueChanged(value) => {
            state.value = value;
        }
    }
}

Implementations§

source§

impl<'a, T, Message, Theme> VerticalSlider<'a, T, Message, Theme>
where T: Copy + From<u8> + PartialOrd, Message: Clone, Theme: Catalog,

source

pub const DEFAULT_WIDTH: f32 = 16f32

The default width of a VerticalSlider.

source

pub fn new<F>( range: RangeInclusive<T>, value: T, on_change: F, ) -> VerticalSlider<'a, T, Message, Theme>
where F: 'a + Fn(T) -> Message,

Creates a new VerticalSlider.

It expects:

  • an inclusive range of possible values
  • the current value of the VerticalSlider
  • a function that will be called when the VerticalSlider is dragged. It receives the new value of the VerticalSlider and must produce a Message.
source

pub fn default( self, default: impl Into<T>, ) -> VerticalSlider<'a, T, Message, Theme>

Sets the optional default value for the VerticalSlider.

If set, the VerticalSlider will reset to this value when ctrl-clicked or command-clicked.

source

pub fn on_release( self, on_release: Message, ) -> VerticalSlider<'a, T, Message, Theme>

Sets the release message of the VerticalSlider. This is called when the mouse is released from the slider.

Typically, the user’s interaction with the slider is finished when this message is produced. This is useful if you need to spawn a long-running task from the slider’s result, where the default on_change message could create too many events.

source

pub fn width( self, width: impl Into<Pixels>, ) -> VerticalSlider<'a, T, Message, Theme>

Sets the width of the VerticalSlider.

source

pub fn height( self, height: impl Into<Length>, ) -> VerticalSlider<'a, T, Message, Theme>

Sets the height of the VerticalSlider.

source

pub fn step(self, step: T) -> VerticalSlider<'a, T, Message, Theme>

Sets the step size of the VerticalSlider.

source

pub fn shift_step( self, shift_step: impl Into<T>, ) -> VerticalSlider<'a, T, Message, Theme>

Sets the optional “shift” step for the VerticalSlider.

If set, this value is used as the step while the shift key is pressed.

source

pub fn style( self, style: impl Fn(&Theme, Status) -> Style + 'a, ) -> VerticalSlider<'a, T, Message, Theme>
where <Theme as Catalog>::Class<'a>: From<Box<dyn Fn(&Theme, Status) -> Style + 'a>>,

Sets the style of the VerticalSlider.

source

pub fn class( self, class: impl Into<<Theme as Catalog>::Class<'a>>, ) -> VerticalSlider<'a, T, Message, Theme>

Sets the style class of the VerticalSlider.
