Struct cursive::views::EnableableView

pub struct EnableableView<V> { /* fields omitted */ }

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::Identifiable;

let mut siv = Cursive::dummy();

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());
        });
    }))
);

Implementations

impl<V> EnableableView<V>

pub fn new(view: V) -> EnableableView<V>

Creates a new EnableableView around view.

It will be enabled by default.

pub fn disable(&mut self)

Disables this view.

A disabled view cannot be selected.

pub fn disabled(self) -> EnableableView<V>

Disables this view.

Chainable variant.

pub fn enable(&mut self)

Re-enables this view.

pub fn set_enabled(&mut self, enabled: bool)

Enable or disable this view.

pub fn with_enabled(self, is_enabled: bool) -> EnableableView<V>

Enable or disable this view.

Chainable variant.

pub fn is_enabled(&self) -> bool

Returns true if this view is enabled.

pub fn get_inner(&self) -> &V

Gets access to the inner view.

pub fn get_inner_mut(&mut self) -> &mut V

Gets mutable access to the inner view.
