Struct cursive::views::EnableableView [−][src]
pub struct EnableableView<V> { /* fields omitted */ }
Expand description
Wrapper around another view that can be enabled/disabled at will.
When disabled, all child views will be disabled and will stop receiving events.
Examples
use cursive_core::Cursive;
use cursive_core::views::{Button, EnableableView, Checkbox, LinearLayout};
use cursive_core::traits::Nameable;
let mut siv = Cursive::new();
siv.add_layer(LinearLayout::vertical()
.child(EnableableView::new(Checkbox::new()).with_name("my_view"))
.child(Button::new("Toggle", |s| {
s.call_on_name("my_view", |v: &mut EnableableView<Checkbox>| {
// This will disable (or re-enable) the checkbox, preventing the user from
// interacting with it.
v.set_enabled(!v.is_enabled());
});
}))
);
