Fields§

§window_state: &'a mut WindowState§event: Event

§world_transform: Affine

The transform from window space to the local space of the target element.

§triggered_by: Option<&'a Event>

The event that caused this synthetic event, if any. Not transformed.

§hit_path: Option<Rc<[ElementId]>>

All visual IDs under the pointer for pointer events.

§phase: Phase

The event phase for this local event.

§target: ElementId

The target of this event.

§source: ElementId

The visual ID that is the source/origin of this event.

§dispatch: Option<Rc<[Dispatch]>>

The full dispatch sequence for this event.

§source_id: ElementId

The element that caused the event to be dispatched.

Implementations§

Source§

impl<'a> EventCx<'a>

Source

pub fn stop_immediate_propagation(&mut self)

Stop propagation to other listeners on this target AND to other nodes in the path.

Source

pub fn prevent_default(&mut self)

Prevent any default actions for this event.

Source

pub fn is_default_prevented(&self) -> bool

Check if preventDefault() was called on this event.

Source

pub fn request_pointer_capture(&mut self, pointer_id: PointerId) -> bool

Request pointer capture for this element.

Source

pub fn start_drag( &mut self, drag_token: DragToken, config: DragConfig, use_default_preview: bool, ) -> bool

where T: Any,

§

fn into_any(self: Box<T>) -> Box<dyn Any>

Convert Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.
