[−][src]Struct kas::widget::Slider
A slider
Sliders allow user input of a value from a fixed range.
Methods
impl<T: SliderType, D: Directional + Default> Slider<T, D>
[src]
pub fn new(min: T, max: T, step: T) -> Self
[src]
Construct a slider
Values vary between the given min
and max
. When keyboard navigation
is used, arrow keys will increment the value by step
and page up/down
keys by step * 16
.
The initial value defaults to the range's
lower bound but may be specified via Slider::with_value
.
impl<T: SliderType, D: Directional> Slider<T, D>
[src]
pub fn new_with_direction(min: T, max: T, step: T, direction: D) -> Self
[src]
Construct a slider with the given direction
Values vary between the given min
and max
. When keyboard navigation
is used, arrow keys will increment the value by step
and page up/down
keys by step * 16
.
The initial value defaults to the range's
lower bound but may be specified via Slider::with_value
.
pub fn with_value(self, value: T) -> Self
[src]
Set the initial value
pub fn value(&self) -> T
[src]
Get the current value
pub fn set_value(&mut self, value: T) -> TkAction
[src]
Set the value
Returns TkAction::Redraw
if a redraw is required.
