Struct cursive_core::views::RadioGroup

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

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: 'static> RadioGroup<T>

pub fn new() -> Self

Creates an empty group for radio buttons.

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

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) -> Rc<T>

Returns the value associated with the selected button.

pub fn set_on_change<F: 'static + Fn(&mut Cursive, &T)>(&mut self, on_change: F)

Sets a callback to be used when the selection changes.

pub fn on_change<F: 'static + Fn(&mut Cursive, &T)>(self, on_change: F) -> Self

Sets a callback to be used when the selection changes.

Chainable variant.

impl RadioGroup<String>

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

Adds a button, using the label itself as value.
