Struct iced_native::widget::radio::Radio

pub struct Radio<Message, Renderer>where
    Renderer: Renderer,
    Renderer::Theme: StyleSheet,{ /* private fields */ }

A circular button representing a choice.

Example

#[derive(Debug, Clone, Copy, PartialEq, Eq)]
pub enum Choice {
    A,
    B,
    C,
    All,
}

#[derive(Debug, Clone, Copy)]
pub enum Message {
    RadioSelected(Choice),
}

let selected_choice = Some(Choice::A);

let a = Radio::new(
    "A",
    Choice::A,
    selected_choice,
    Message::RadioSelected,
);

let b = Radio::new(
    "B",
    Choice::B,
    selected_choice,
    Message::RadioSelected,
);

let c = Radio::new(
    "C",
    Choice::C,
    selected_choice,
    Message::RadioSelected,
);

let all = Radio::new(
    "All of the above",
    Choice::All,
    selected_choice,
    Message::RadioSelected
);

let content = column![a, b, c, all];

Implementations

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

pub const DEFAULT_SIZE: f32 = 28f32

The default size of a Radio button.

pub const DEFAULT_SPACING: f32 = 15f32

The default spacing of a Radio button.

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.

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

Sets the size of the Radio button.

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

Sets the width of the Radio button.

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

Sets the spacing between the Radio button and the text.

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

Sets the text size of the Radio button.

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

Sets the text font of the Radio button.

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

Sets the style of the Radio button.

fn tag(&self) -> Tag

Returns the Tag of the Widget.

fn state(&self) -> State

Returns the State of the Widget.

fn children(&self) -> Vec<Tree>
