Struct ListSelectionChanged 

pub struct ListSelectionChanged {
    pub old_selection: Option<usize>,
    pub new_selection: Option<usize>,
}

Event fired when a list’s selection changes

Fields

old_selection: Option<usize>

The previous selection index

new_selection: Option<usize>

The new selection index

Implementations

impl ListSelectionChanged

pub fn listener() -> ListSelectionChangedListener

Get the event listener for this custom event

pub fn extract(event: &Event) -> Option<&ListSelectionChanged>

Attempt to extract this event type from a generic Event.

Equivalent to: Self::listener_key().extract(event)

Trait Implementations

impl Clone for ListSelectionChanged

fn clone(&self) -> ListSelectionChanged

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CustomEvent for ListSelectionChanged

fn listener_key() -> EventListenerKey

Get the unique key for this event type

fn listener_key_dyn(&self) -> EventListenerKey

Get the listener key for this trait object

fn as_any(&self) -> &(dyn Any + 'static)

Downcast helper

fn clone_box(&self) -> Box<dyn CustomEvent>

Clone this event into a Box without requiring Clone on the trait

fn transform(&mut self, transform: Affine)

fn allow_disabled(&self) -> bool

fn debug_fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Format for Debug output. Default uses the type name.

impl Debug for ListSelectionChanged

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl PartialEq for ListSelectionChanged

fn eq(&self, other: &ListSelectionChanged) -> 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.
