Trait Implementations

impl Event for TrackballEvent

where Self: Send + Sync + 'static,

const AUTO_PROPAGATE: bool = false

When true, this event will always attempt to propagate when triggered, without requiring a call to Trigger::propagate.

type Traversal = ()

The component that describes which Entity to propagate this event to next, when propagation is enabled.

fn register_component_id(world: &mut World) -> ComponentId

Generates the ComponentId for this event type.

fn component_id(world: &World) -> Option<ComponentId>

Fetches the ComponentId for this event type, if it has already been generated.
