Struct cursive::prelude::KeyEventView
[−]
[src]
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());
