pub struct Button<'a, Message, Renderer>where
    Renderer: Renderer,
    Renderer::Theme: StyleSheet,
{ /* private fields */ }
Expand description

A generic widget that produces a message when pressed.

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

let button = Button::new("Press me!").on_press(Message::ButtonPressed);

If a Button::on_press handler is not set, the resulting Button will be disabled:

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

fn disabled_button<'a>() -> Button<'a, Message> {
    Button::new("I'm disabled!")
}

fn enabled_button<'a>() -> Button<'a, Message> {
    disabled_button().on_press(Message::ButtonPressed)
}
