Struct WheelData 

pub struct WheelData { /* private fields */ }

Available on crate feature prelude only.

Data associated with a WheelEvent

Implementations

impl WheelData

pub fn new(inner: impl HasWheelData + 'static) -> WheelData

pub fn delta(&self) -> WheelDelta

The amount of wheel movement

pub fn downcast<T>(&self) -> Option<&T>

where T: 'static,

Downcast this event to a concrete event type

Trait Implementations

impl Debug for WheelData

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

Formats the value using the given formatter.

impl From<&PlatformEventData> for WheelData

fn from(val: &PlatformEventData) -> WheelData

Converts to this type from the input type.

impl<E> From<E> for WheelData

where E: HasWheelData,

fn from(e: E) -> WheelData

Converts to this type from the input type.

impl InteractionElementOffset for WheelData

fn element_coordinates(&self) -> Point2D<f64, ElementSpace>

Gets the coordinates of the event relative to the target element.

fn coordinates(&self) -> Coordinates

Gets the coordinates of the event.

impl InteractionLocation for WheelData

fn client_coordinates(&self) -> Point2D<f64, ClientSpace>

Gets the coordinates of the event relative to the browser viewport.

fn page_coordinates(&self) -> Point2D<f64, PageSpace>

Gets the coordinates of the event relative to the page.

fn screen_coordinates(&self) -> Point2D<f64, ScreenSpace>

Gets the coordinates of the event relative to the screen.

impl ModifiersInteraction for WheelData

fn modifiers(&self) -> Modifiers

Gets the modifiers of the pointer event.

impl PartialEq for WheelData

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

impl PointerInteraction for WheelData

fn held_buttons(&self) -> EnumSet<MouseButton>

Gets the buttons that are currently held down.

fn trigger_button(&self) -> Option<MouseButton>

Gets the button that triggered the event.
