Struct cursive::views::KeyEventView

pub struct KeyEventView {
    // some fields omitted
}

A simple wrapper view that catches some ignored event from its child.

If the event doesn't have a corresponding callback, it will stay ignored.

Examples

let view = KeyEventView::new(TextView::new("This view has an event!"))
                        .register('q', |s| s.quit())
                        .register(Key::Esc, |s| s.quit());
