Implementations

impl<'a, Message, Renderer: Renderer, ID> ModRangeInput<'a, Message, Renderer, ID> where
    ID: Debug + Copy + Clone, 

pub fn new<F>(state: &'a mut State<ID>, on_change: F) -> Self where
    F: 'static + Fn(ID) -> Message, 

Creates a new ModRangeInput.

It expects:

• the local State of the ModRangeInput
• a function that will be called when the ModRangeInput is turned.

pub fn size(self, size: Length) -> Self

Sets the diameter of the ModRangeInput. The default size is Length::from(Length::Units(31)).

pub fn style(self, style: impl Into<Renderer::Style>) -> Self

Sets the style of the ModRangeInput.

pub fn scalar(self, scalar: f32) -> Self

Sets how much the Normal value will change for the ModRangeInput per y pixel movement of the mouse.

The default value is 0.008

pub fn modifier_keys(self, modifier_keys: ModifiersState) -> Self

Sets the modifier keys of the ModRangeInput.

The default modifier key is Ctrl.

pub fn modifier_scalar(self, scalar: f32) -> Self

Sets the scalar to use when the user drags the ModRangeInputs while holding down the modifier key. This is multiplied to the value set by ModRangeInput::scalar() (which the default is 0.008).

For example, a modifier_scalar of 0.5 will cause the ModRangeInput to turn half as fast when the modifier key is down.

The default modifier_scalar is 0.02, and the default modifier key is Ctrl.
