Struct iced::widget::radio::Radio

pub struct Radio<Color, Message> { /* fields omitted */ }

A circular button representing a choice, with a generic text Color.

It implements Widget when the associated Renderer implements the radio::Renderer trait.

Example

use iced::{Column, Radio};

#[derive(Debug, Clone, Copy)]
pub enum Color {
    Black,
}

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

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

let selected_choice = Some(Choice::A);

Radio::new(Choice::A, "This is A", selected_choice, Message::RadioSelected)
    .label_color(Color::Black);

Radio::new(Choice::B, "This is B", selected_choice, Message::RadioSelected)
    .label_color(Color::Black);

Methods

impl<Color, Message> Radio<Color, Message>

pub fn new<F, V>(value: V, label: &str, selected: Option<V>, f: F) -> Self where
    V: Eq + Copy,
    F: 'static + Fn(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 label_color(self, color: Color) -> Self

Sets the Color of the label of the Radio.
