Struct RadioGroup

pub struct RadioGroup<T> { /* private fields */ }

Group to coordinate multiple radio buttons.

A RadioGroup is used to create and manage RadioButtons.

A RadioGroup can be cloned; it will keep pointing to the same group.

Implementations

impl<T> RadioGroup<T>

where T: 'static + Send + Sync,

pub fn new() -> RadioGroup<T>

Creates an empty group for radio buttons.

pub fn global<S>(key: S) -> RadioGroup<T>

where S: Into<String>,

Get a global group based on a key and T type.

pub fn with_global<F, R, S>(key: S, f: F) -> R

where S: Into<String>, F: FnOnce(&mut RadioGroup<T>) -> R,

Run a closure on a radio group from a global pool.

If none exist with the given type T and key, a new one will be created.

pub fn button<S>(&mut self, value: T, label: S) -> RadioButton<T>

where S: Into<SpannedString<Style>>,

Adds a new button to the group.

The button will display label next to it, and will embed value.

pub fn selected_id(&self) -> usize

Returns the id of the selected button.

Buttons are indexed in the order they are created, starting from 0.

pub fn selection(&self) -> Arc<T>

Returns the value associated with the selected button.

Panics

If the group is empty (no button).

pub fn set_on_change<F>(&mut self, on_change: F)

where F: 'static + Fn(&mut Cursive, &T) + Send + Sync,

Sets a callback to be used when the selection changes.

pub fn on_change<F>(self, on_change: F) -> RadioGroup<T>

where F: 'static + Fn(&mut Cursive, &T) + Send + Sync,

Sets a callback to be used when the selection changes.

Chainable variant.

impl RadioGroup<String>

pub fn button_str<S>(&mut self, text: S) -> RadioButton<String>

where S: Into<String>,

Adds a button, using the label itself as value.

Trait Implementations

impl<T> Clone for RadioGroup<T>

fn clone(&self) -> RadioGroup<T>

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl<T> Default for RadioGroup<T>

where T: 'static + Send + Sync,

fn default() -> RadioGroup<T>

Returns the “default value” for a type.

impl Resolvable for RadioGroup<String>

fn from_config( config: &Value, context: &Context, ) -> Result<RadioGroup<String>, Error>

Build from a config (a JSON value).

fn from_any(any: Box<dyn Any>) -> Option<Self>

where Self: Sized + Any,

Build from an Any variable.
