Struct Spinner

pub struct Spinner { /* private fields */ }

Creates a spinner widget

Implementations

impl Spinner

pub fn new<'a, T: Into<Option<&'a str>>>( x: i32, y: i32, width: i32, height: i32, title: T, ) -> Spinner

Creates a new widget, takes an x, y coordinates, as well as a width and height, plus a title

Arguments

• x - The x coordinate in the screen
• y - The y coordinate in the screen
• width - The width of the widget
• heigth - The height of the widget
• title - The title or label of the widget

To use dynamic strings use with_label(self, &str) or set_label(&mut self, &str). labels support special symbols preceded by an @ sign and for the associated formatting.

pub fn default_fill() -> Self

Constructs a widget with the size of its parent

impl Spinner

pub fn minimum(&self) -> f64

Returns the minimum value of the spinner widget

pub fn set_minimum(&mut self, a: f64)

Sets the minimum value of the spinner widget

pub fn maximum(&self) -> f64

Returns the maximum value of the spinner widget

pub fn set_maximum(&mut self, a: f64)

Sets the minimum value of the spinner widget

pub fn set_range(&mut self, a: f64, b: f64)

Sets the range of the spinner widget
