pub struct Slider<'a, T, Message, Theme = Theme>where
Theme: StyleSheet,{ /* private fields */ }
Expand description
An horizontal bar and a handle that selects a single value from a range of values.
A Slider
will try to fill the horizontal space of its container.
The Slider
range of numeric values is generic and its step size defaults
to 1 unit.
§Example
#[derive(Clone)]
pub enum Message {
SliderChanged(f32),
}
let value = 50.0;
Slider::new(0.0..=100.0, value, Message::SliderChanged);
Implementations§
source§impl<'a, T, Message, Theme> Slider<'a, T, Message, Theme>
impl<'a, T, Message, Theme> Slider<'a, T, Message, Theme>
sourcepub const DEFAULT_HEIGHT: f32 = 22f32
pub const DEFAULT_HEIGHT: f32 = 22f32
The default height of a Slider
.
sourcepub fn new<F>(
range: RangeInclusive<T>,
value: T,
on_change: F
) -> Slider<'a, T, Message, Theme>where
F: 'a + Fn(T) -> Message,
pub fn new<F>(
range: RangeInclusive<T>,
value: T,
on_change: F
) -> Slider<'a, T, Message, Theme>where
F: 'a + Fn(T) -> Message,
sourcepub fn on_release(self, on_release: Message) -> Slider<'a, T, Message, Theme>
pub fn on_release(self, on_release: Message) -> Slider<'a, T, Message, Theme>
Sets the release message of the Slider
.
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.
sourcepub fn width(self, width: impl Into<Length>) -> Slider<'a, T, Message, Theme>
pub fn width(self, width: impl Into<Length>) -> Slider<'a, T, Message, Theme>
Sets the width of the Slider
.
sourcepub fn height(self, height: impl Into<Pixels>) -> Slider<'a, T, Message, Theme>
pub fn height(self, height: impl Into<Pixels>) -> Slider<'a, T, Message, Theme>
Sets the height of the Slider
.
sourcepub fn style(
self,
style: impl Into<<Theme as StyleSheet>::Style>
) -> Slider<'a, T, Message, Theme>
pub fn style( self, style: impl Into<<Theme as StyleSheet>::Style> ) -> Slider<'a, T, Message, Theme>
Sets the style of the Slider
.
sourcepub fn step(self, step: impl Into<T>) -> Slider<'a, T, Message, Theme>
pub fn step(self, step: impl Into<T>) -> Slider<'a, T, Message, Theme>
Sets the step size of the Slider
.
sourcepub fn shift_step(
self,
shift_step: impl Into<T>
) -> Slider<'a, T, Message, Theme>
pub fn shift_step( self, shift_step: impl Into<T> ) -> Slider<'a, T, Message, Theme>
Sets the optional “shift” step for the Slider
.
If set, this value is used as the step while the shift key is pressed.
