Struct ScrollChanged 

pub struct ScrollChanged {
    pub offset: Vec2,
}

Event fired when a scroll view’s scroll position changes

This event is fired whenever the visible viewport of the scroll view changes, either through user interaction (scrolling with mouse wheel, dragging scrollbars) or programmatic changes to the scroll offset.

Fields

offset: Vec2

The scroll offset as a vector (how far scrolled from origin)

Implementations

impl ScrollChanged

pub fn listener() -> ScrollChangedListener

Get the event listener for this custom event

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

Attempt to extract this event type from a generic Event.

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

Trait Implementations

impl Clone for ScrollChanged

fn clone(&self) -> ScrollChanged

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CustomEvent for ScrollChanged

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 ScrollChanged

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

Formats the value using the given formatter.

impl PartialEq for ScrollChanged

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