Struct iced_audio::native::v_slider::VSlider

pub struct VSlider<'a, Message, Renderer: Renderer, ID> where
    ID: Debug + Copy + Clone,  { /* fields omitted */ }

A vertical slider GUI widget that controls a Param

a VSlider will try to fill the vertical space of its container.

Implementations

impl<'a, Message, Renderer: Renderer, ID> VSlider<'a, Message, Renderer, ID> where
    ID: Debug + Copy + Clone, 

pub fn new<F>(state: &'a mut State<ID>, on_change: F) -> Self where
    F: 'static + Fn(ID) -> Message, 

Creates a new VSlider.

It expects:

• the local State of the VSlider
• a function that will be called when the VSlider is dragged.

pub fn width(self, width: Length) -> Self

Sets the width of the VSlider. The default width is Length::from(Length::Units(16)).

pub fn height(self, height: Length) -> Self

Sets the height of the VSlider. The default height is Length::Fill.

pub fn style(self, style: impl Into<Renderer::Style>) -> Self

Sets the style of the VSlider.

pub fn modifier_keys(self, modifier_keys: ModifiersState) -> Self

Sets the modifier keys of the VSlider.

The default modifier key is Ctrl.

pub fn modifier_scalar(self, scalar: f32) -> Self

Sets the scalar to use when the user drags the slider while holding down the modifier key.

For example, a scalar of 0.5 will cause the slider to move half a pixel for every pixel the mouse moves.

The default scalar is 0.02, and the default modifier key is Ctrl.

pub fn tick_marks(self, tick_marks: &'a TickMarkGroup) -> Self

Sets the TickMarkGroup to display. Note your StyleSheet must also implement tick_mark_style(&self) -> Option<TickMarkStyle> for them to display (which the default style does).

fn from(
    v_slider: VSlider<'a, Message, Renderer, ID>
) -> Element<'a, Message, Renderer>

Performs the conversion.

impl<'a, Message, Renderer, ID> Widget<Message, Renderer> for VSlider<'a, Message, Renderer, ID> where

    ID: Debug + Copy + Clone, 

fn width(&self) -> Length

Returns the width of the [Widget].

fn height(&self) -> Length

Returns the height of the [Widget].

fn layout(&self, _renderer: &Renderer, limits: &Limits) -> Node

Returns the [Node] of the [Widget].

fn on_event(
    &mut self,
    event: Event,
    layout: Layout,
    cursor_position: Point,
    messages: &mut Vec<Message>,
    _renderer: &Renderer,
    _clipboard: Option<&dyn Clipboard>
)

Processes a runtime [Event].

fn draw(
    &self,
    renderer: &mut Renderer,
    _defaults: &Renderer::Defaults,
    layout: Layout,
    cursor_position: Point
) -> Renderer::Output

Draws the [Widget] using the associated Renderer.

fn hash_layout(&self, state: &mut Hasher)

Computes the layout hash of the [Widget].
