type Error = ConversionError

The type returned in the event of a conversion error.

fn try_from(value: DragRelatedEvent) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<DragEnterEvent> for Reference

type Error = Void

The type returned in the event of a conversion error.

fn try_from(value: DragEnterEvent) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Reference> for DragEnterEvent

type Error = ConversionError

The type returned in the event of a conversion error.

fn try_from(reference: Reference) -> Result<Self, Self::Error>

Performs the conversion.

impl<'_r> TryFrom<&'_r Reference> for DragEnterEvent

type Error = ConversionError

The type returned in the event of a conversion error.

fn try_from(reference: &Reference) -> Result<Self, Self::Error>

Performs the conversion.

impl TryFrom<Value> for DragEnterEvent

type Error = ConversionError

The type returned in the event of a conversion error.

fn try_from(value: Value) -> Result<Self, Self::Error>

Performs the conversion.

impl<'_r> TryFrom<&'_r Value> for DragEnterEvent

type Error = ConversionError

The type returned in the event of a conversion error.

fn try_from(value: &Value) -> Result<Self, Self::Error>

Performs the conversion.

impl InstanceOf for DragEnterEvent

fn instance_of(reference: &Reference) -> bool

Checks whenever a given Reference if of type Self.

impl ReferenceType for DragEnterEvent

unsafe fn from_reference_unchecked(reference: Reference) -> Self

Converts a given reference into a concrete reference-like wrapper. Doesn't do any type checking; highly unsafe to use!

impl IEvent for DragEnterEvent

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.

fn time_stamp(&self) -> Option<f64>

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 ConcreteEvent for DragEnterEvent

const EVENT_TYPE: &'static str

A string representing the event type.

impl IUiEvent for DragEnterEvent

fn detail(&self) -> i32

Provides the current click count for this event, if applicable.

fn view(&self) -> Option<Window>

Returns the WindowProxy that generated the event.

impl IDragEvent for DragEnterEvent

fn data_transfer(&self) -> Option<DataTransfer>

The DataEvent.dataTransfer property holds the drag operation's data (as a DataTransfer object).

impl IMouseEvent for DragEnterEvent

fn alt_key(&self) -> bool

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

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.

fn offset_x(&self) -> f64

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.
