Struct scl_gui_widgets::widgets::RangeSlider

pub struct RangeSlider { /* private fields */ }

A range slider, allowing interactive update of two numeric values .

This slider implements Widget<(f64, f64)>, and works on value pairs clamped in the range min..max, where the left value is always smaller than the right.

Implementations

impl RangeSlider

pub fn new() -> RangeSlider

Create a new RangeSlider.

pub fn with_range(self, min: f64, max: f64) -> Self

Builder-style method to set the range covered by this range slider.

The default range is 0.0..1.0.

pub fn with_step(self, step: f64) -> Self

Builder-style method to set the stepping.

The default step size is 0.0 (smooth).

pub fn knob_style(self, knob_style: KnobStyle) -> Self

Builder-style method to set the knob style.

The default is Circle.

pub fn axis(self, axis: Axis) -> Self

Builder-style method to the the axis on which the slider moves.

The default is Horizontal.

pub fn get_mapping(&self) -> SliderValueMapping

Returns the Mapping of this Slider.

pub fn annotated( self, named_steps: f64, unnamed_steps: f64 ) -> Annotated<(f64, f64), Self>

Builder-style method to create an annotated range slider.
