pub fn new_range(range: (T, T), step: T::Step) -> Self

New state with a given range and step.

The range will still be overridden when set with the Widget.

pub fn set_value(&mut self, value: T) -> bool

Set the value.

Any value you set is good, there will be no bounds check. Without user interaction the same value will be returned by value().

pub fn value(&self) -> T

Current value.

pub fn set_range(&mut self, range: (T, T))

Set the range.

pub fn range(&self) -> (T, T)

Range.

pub fn set_step(&mut self, step: T::Step)

Minor step size.

pub fn step(&self) -> T::Step

Minor step size.

pub fn set_long_step(&mut self, step: T::Step)

Major step size.

pub fn long_step(&self) -> Option<T::Step>

Major step size.

pub fn next(&mut self) -> bool

Next value by one step.

pub fn prev(&mut self) -> bool

Previous value by one step.

pub fn next_major(&mut self) -> bool

Next value by one major step.

pub fn prev_major(&mut self) -> bool

Previous value by one major step.

pub fn clicked_at(&mut self, x: u16, y: u16) -> bool

Clicked in the range or at the boundary. Transforms the relative screen position to a value.
