Struct Radio 

pub struct Radio {
    pub id: Option<NodeId>,
    pub checked: bool,
    pub on_select: Option<ActionEnvelope>,
    pub label: Option<String>,
}

A single-select radio button with a circular indicator and optional label.

Radio buttons are typically used in a group where exactly one is selected at a time. The on_select action is dispatched when the user taps the button; the application updates which option is selected in the reducer.

Example

for (i, option) in options.iter().enumerate() {
    let on_select = ctx.bind(
        SelectOption { index: i },
        reduce_with!(handle_select),
    );
    children.push(Radio {
        checked: view.state.selected == i,
        on_select: Some(on_select),
        label: Some(option.clone()),
        ..Default::default()
    }.into_node().into());
}

Fields

id: Option<NodeId>

Explicit node identity.

checked: bool

Whether this radio button is currently selected.

on_select: Option<ActionEnvelope>

Action dispatched when this radio button is tapped.

label: Option<String>

Optional text label rendered next to the indicator.
