Struct SelectorBar 

pub struct SelectorBar<'a, Id, Message, Theme = Theme, Renderer = Renderer>
where
    Theme: Catalog + Catalog,
{ /* private fields */ }

Available on crate feature selector_bar only.

A SelectorBar provides single selection from a collection of Items highlighted by an indicator.

Example

#[derive(Clone)]
enum Message {
   TabSelected(u32),
}

fn view(&self) -> Element<'_, Message, Theme> {
    let tabs = (0..5).map(|i| item(i, text!("Tab {}", i + 1)));
    selector_bar(tabs, self.selected_tab, Message::TabSelected).into()
}
