Struct kas_widgets::Slider
source · pub struct Slider<A, T: SliderValue, D: Directional = Direction> { /* private fields */ }
Expand description
A slider
Sliders allow user input of a value from a fixed range.
Implementations§
source§impl<A, T: SliderValue, D> Slider<A, T, D>where
D: Default + Directional,
impl<A, T: SliderValue, D> Slider<A, T, D>where
D: Default + Directional,
sourcepub fn new(
range: RangeInclusive<T>,
state_fn: impl Fn(&ConfigCx<'_>, &A) -> T + 'static
) -> Self
pub fn new( range: RangeInclusive<T>, state_fn: impl Fn(&ConfigCx<'_>, &A) -> T + 'static ) -> Self
Construct a slider
Values vary within the given range
, increasing in the given
direction
. The default step size is
1 for common types (see SliderValue::default_step
).
The slider’s current value is set by state_fn
on update.
To make the slider interactive, assign an event handler with
Self::with
or Self::with_msg
.

pub fn new_dir( range: RangeInclusive<T>, state_fn: impl Fn(&ConfigCx<'_>, &A) -> T + 'static, direction: D ) -> Self
Construct a slider with given direction
Values vary within the given range
, increasing in the given
direction
. The default step size is
1 for common types (see SliderValue::default_step
).
The slider’s current value is set by state_fn
on update.
