Struct conrod::Slider

pub struct Slider<'a, T, F> {
    pub skew: f32,
    pub maybe_react: Option<F>,
    pub enabled: bool,
    // some fields omitted
}

Linear value selection. If the slider's width is greater than it's height, it will automatically become a horizontal slider, otherwise it will be a vertical slider. Its reaction is triggered if the value is updated or if the mouse button is released while the cursor is above the rectangle.

Fields

skew: f32

The amount in which the slider's display should be skewed.

Higher skew amounts (above 1.0) will weight lower values.

Lower skew amounts (below 1.0) will weight heigher values.

All skew amounts should be greater than 0.0.

maybe_react: Option<F>

Set the reaction for the Slider.

It will be triggered if the value is updated or if the mouse button is released while the cursor is above the rectangle.

enabled: bool

Whether or not user input is enabled for the Slider.

Trait Implementations

impl<'a, T, F> Widget for Slider<'a, T, F> where F: FnOnce(T), T: Any + Debug + Float + NumCast + ToPrimitive

type State = State<T>

State to be stored within the Uis widget cache.

type Style = Style

Every widget is required to have its own associated Style type. This type is intended to contain high-level styling information for the widget that can be optionally specified by a user of the widget.

Return a reference to a CommonBuilder struct owned by the Widget. This method allows us to do a blanket impl of Positionable and Sizeable for T: Widget.

fn common_mut(&mut self) -> &mut CommonBuilder

Return a mutable reference to a CommonBuilder struct owned by the Widget. This method allows us to do a blanket impl of Positionable and Sizeable for T: Widget.

fn unique_kind(&self) -> &'static str

Return the kind of the widget as a &'static str.

fn init_state(&self) -> State<T>

Return the initial State of the Widget.

fn style(&self) -> Style

Return the styling of the widget.

fn kid_area<C: CharacterCache>(&self, args: KidAreaArgs<Self, C>) -> KidArea

The default height of the widget.

fn drag_area(&self, _dim: Dimensions, _style: &Self::Style, _theme: &Theme) -> Option<Rect>

If the widget is draggable, implement this method and return the position an dimensions of the draggable space. The position should be relative to the center of the widget.

Indicates that the Widget is used as a non-interactive graphical element for some other widget.

fn floating(self, is_floating: bool) -> Self

Set whether or not the widget is floating (the default is false). A typical example of a floating widget would be a pop-up or alert window.

fn scroll_kids(self) -> Self

Set whether or not the widget's KidArea is scrollable (the default is false).

fn scroll_kids_vertically(self) -> Self

Set whether or not the widget's KidArea is scrollable (the default is false).

A method that optionally builds the the Widget with the given build function.

fn set<I, U>(self, idx: I, ui: &mut U) where I: Into<Index>, U: UiRefMut
