Struct PointerData

pub struct PointerData { /* private fields */ }

Implementations

impl PointerData

pub fn new(data: impl HasPointerData + 'static) -> PointerData

Create a new PointerData

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

where T: 'static,

Downcast this event to a concrete event type

impl PointerData

pub fn pointer_id(&self) -> i32

Gets the unique identifier of the pointer causing the event.

pub fn width(&self) -> i32

Gets the width (magnitude on the X axis), in CSS pixels, of the contact geometry of the pointer.

pub fn height(&self) -> i32

Gets the height (magnitude on the Y axis), in CSS pixels, of the contact geometry of the pointer.

pub fn pressure(&self) -> f32

Gets the normalized pressure of the pointer input in the range of 0 to 1,

pub fn tangential_pressure(&self) -> f32

Gets the normalized tangential pressure of the pointer input (also known as barrel pressure or cylinder stress) in the range -1 to 1,

pub fn tilt_x(&self) -> i32

Gets the plane angle (in degrees, in the range of -90 to 90) between the Y-Z plane and the plane containing both the transducer (e.g. pen stylus) axis and the Y axis.

pub fn tilt_y(&self) -> i32

Gets the plane angle (in degrees, in the range of -90 to 90) between the X-Z plane and the plane containing both the transducer (e.g. pen stylus) axis and the X axis.

pub fn twist(&self) -> i32

Gets the clockwise rotation of the pointer (e.g. pen stylus) around its major axis in degrees, with a value in the range 0 to 359.The clockwise rotation of the pointer (e.g. pen stylus) around its major axis in degrees, with a value in the range 0 to 359.

pub fn pointer_type(&self) -> String

Gets the device type that caused the event (mouse, pen, touch, etc.).

pub fn is_primary(&self) -> bool

Gets if the pointer represents the primary pointer of this pointer type.

Trait Implementations

impl Debug for PointerData

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

Formats the value using the given formatter.

impl From<&PlatformEventData> for PointerData

fn from(val: &PlatformEventData) -> PointerData

Converts to this type from the input type.

impl<E> From<E> for PointerData

where E: HasPointerData + 'static,

fn from(e: E) -> PointerData

Converts to this type from the input type.

impl InteractionElementOffset for PointerData

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 PointerData

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

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

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

Gets the coordinates of the event relative to the screen.

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

Gets the coordinates of the event relative to the page.

impl ModifiersInteraction for PointerData

fn modifiers(&self) -> Modifiers

Gets the modifiers of the pointer event.

impl PartialEq for PointerData

fn eq(&self, other: &PointerData) -> 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 PointerData

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.
