Struct Selection 

pub struct Selection<K: Clone + PartialEq + 'static> { /* private fields */ }

Selection state for keys of type K. Cheap to copy.

Implementations

impl<K: Clone + PartialEq + 'static> Selection<K>

pub fn from_signal(items: Signal<Vec<K>>) -> Self

Wrap an existing signal. Prefer use_selection.

pub fn is_selected(&self, key: &K) -> bool

Is key currently selected?

pub fn select_only(&mut self, key: K)

Replace the selection with just key.

pub fn toggle(&mut self, key: K)

Add or remove key (Ctrl/Cmd+click semantics).

pub fn clear(&mut self)

Clear the selection.

pub fn items(&self) -> Vec<K>

Snapshot of the selected keys, in selection order.

pub fn len(&self) -> usize

Number of selected keys.

pub fn is_empty(&self) -> bool

Is nothing selected?

pub fn click(&mut self, key: K, modifiers: Modifiers)

Apply the standard click convention: plain click selects only this key; a click with Ctrl or Cmd held toggles it.

Trait Implementations

impl<K: Clone + PartialEq + 'static> Clone for Selection<K>

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<K: Clone + PartialEq + 'static> Copy for Selection<K>

impl<K: Clone + PartialEq + 'static> PartialEq for Selection<K>

fn eq(&self, other: &Self) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
