Struct iced_native::widget::radio::Radio

pub struct Radio<Message, Renderer: Renderer + Renderer> { /* fields omitted */ }

A circular button representing a choice.

Example

#[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);

Radio::new(Choice::B, "This is B", selected_choice, Message::RadioSelected);

Implementations

impl<Message, Renderer: Renderer + Renderer> Radio<Message, Renderer> where
    Message: Clone, 

pub fn new<F, V>(
    value: V,
    label: impl Into<String>,
    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 size(self, size: u16) -> Self

Sets the size of the Radio button.

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

Sets the width of the Radio button.

pub fn spacing(self, spacing: u16) -> Self

Sets the spacing between the Radio button and the text.

pub fn text_size(self, text_size: u16) -> Self

Sets the text size of the Radio button.

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

Sets the style of the Radio button.

) -> Option<Element<'_, Message, Renderer>>

Returns the overlay of the Widget, if there is any.
