Struct PointerEnterEvent

pub struct PointerEnterEvent(/* private fields */);

The PointerEnterEvent is fired when a pointing device is moved into the hit test boundaries of an element or its descendants. This event does not bubble.

Trait Implementations

impl AsRef<Reference> for PointerEnterEvent

fn as_ref(&self) -> &Reference

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for PointerEnterEvent

fn clone(&self) -> PointerEnterEvent

Returns a copy of the value.

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

impl ConcreteEvent for PointerEnterEvent

const EVENT_TYPE: &'static str = "pointerenter"

A string representing the event type.

impl Debug for PointerEnterEvent

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

Formats the value using the given formatter.

impl From<PointerEnterEvent> for Reference

fn from(value: PointerEnterEvent) -> Self

Converts to this type from the input type.

impl IEvent for PointerEnterEvent

fn bubbles(&self) -> bool

Indicates whether this event bubbles upward through the DOM.

fn cancel_bubble(&self) -> bool

A historical alias to Event.stopPropagation().

fn set_cancel_bubble(&self, value: bool)

A historical alias to Event.stopPropagation(). Setting this to true before returning from an event handler will stop propagation of the event.

fn cancelable(&self) -> bool

Indicates whether the event is cancelable.

fn current_target(&self) -> Option<EventTarget>

A reference to the currently registered target of this event.

fn default_prevented(&self) -> bool

Indicates whether preventDefault has been called on this event.

fn event_phase(&self) -> EventPhase

Indicates which phase of event flow is currently being evaluated.

fn stop_immediate_propagation(&self)

Prevents any further listeners from being called for this event.

fn stop_propagation(&self)

Stops the propagation of this event to descendants in the DOM.

fn target(&self) -> Option<EventTarget>

Returns a reference to the target to which this event was originally registered.

Returns the time in milliseconds at which this event was created.

fn is_trusted(&self) -> bool

Indicates whether the event was generated by a user action.

fn event_type(&self) -> String

Returns a string containing the type of event. It is set when the event is constructed and is the name commonly used to refer to the specific event.

fn prevent_default(&self)

Cancels the event if it is cancelable, without stopping further propagation of the event.

impl IMouseEvent for PointerEnterEvent

fn alt_key(&self) -> bool

Returns whether the Alt key was down when this event was fired.

fn button(&self) -> MouseButton

Indicates the mouse button that fired this event.

fn buttons(&self) -> MouseButtonsState

Indicates which mouse buttons were down when this event was fired.

fn client_x(&self) -> i32

Returns the X position in the application’s client area where this event occured.

fn client_y(&self) -> i32

Returns the Y position in the application’s client area where this event occured.

Returns the X position on the target element where this event occured.

fn offset_y(&self) -> f64

Returns the Y position on the target element where this event occured.

fn ctrl_key(&self) -> bool

Indicates whether the Ctrl key was down when this event fired.

fn get_modifier_state(&self, key: ModifierKey) -> bool

Returns the current state of the specified modifier key.

fn meta_key(&self) -> bool

Indicates whether the Meta key was down when this event fired.

fn movement_x(&self) -> i32

Returns the change in X coordinate of the pointer between this event and the previous MouseMove event.

fn movement_y(&self) -> i32

Returns the change in Y coordinate of the pointer between this event and the previous MouseMove event.

fn region(&self) -> Option<String>

Returns the ID of the hit region affected by the event.

fn related_target(&self) -> Option<EventTarget>

Returns the secondary target of this event, if any.

fn screen_x(&self) -> i32

Returns the X position of the pointer in screen coordinates.

fn screen_y(&self) -> i32

Returns the Y position of the pointer in screen coordinates.

fn shift_key(&self) -> bool

Indicates whether the Shift key was down when this event was fired.

impl IPointerEvent for PointerEnterEvent

fn pointer_id(&self) -> i32

Returns a unique identifier for the pointer causing the event.

fn width(&self) -> f64

Returns the width, in CSS pixels, of the contact geometry of the pointer.

fn height(&self) -> f64

Returns the height, in CSS pixels, of the contact geometry of the pointer.

fn pressure(&self) -> f64

Returns the normalized pressure of the pointer in the range [0, 1]

fn tangential_pressure(&self) -> f64

Returns the normalized tangential pressure of the pointer in the range [-1, 1], where 0 is the hardware’s neutral position

fn tilt_x(&self) -> i32

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

fn tilt_y(&self) -> i32

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

fn twist(&self) -> i32

Returns the clockwise rotation, in the range of [0, 359] degrees, of the transducer (e.g. pen stylus) around it’s own major axis

impl InstanceOf for PointerEnterEvent

fn instance_of(reference: &Reference) -> bool

Checks whenever a given Reference if of type Self.

impl PartialEq for PointerEnterEvent

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

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