Implementations§

source§

impl<Message, Renderer> Radio<Message, Renderer>where Message: Clone, Renderer: Renderer, Renderer::Theme: StyleSheet,

source

pub const DEFAULT_SIZE: f32 = 28f32

The default size of a Radio button.

source

pub const DEFAULT_SPACING: f32 = 15f32

The default spacing of a Radio button.

source

pub fn new<F, V>( label: impl Into<String>, value: V, selected: Option<V>, f: F ) -> Selfwhere V: Eq + Copy, F: FnOnce(V) -> Message,

Creates a new Radio button.

It expects:

  • the value related to the Radio button
  • the label of the Radio button
  • the current selected value
  • a function that will be called when the Radio is selected. It receives the value of the radio and must produce a Message.
source

pub fn size(self, size: impl Into<Pixels>) -> Self

Sets the size of the Radio button.

source

pub fn width(self, width: impl Into<Length>) -> Self

Sets the width of the Radio button.

source

pub fn spacing(self, spacing: impl Into<Pixels>) -> Self

Sets the spacing between the Radio button and the text.

source

pub fn text_size(self, text_size: impl Into<Pixels>) -> Self

Sets the text size of the Radio button.

source

pub fn font(self, font: Renderer::Font) -> Self

Sets the text font of the Radio button.

source

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

Sets the style of the Radio button.
