Enum DispatchInput

    Pointer {
        x: i32,
        y: i32,
        event: Event,
    },
    PointerObject {

Expand description

The input to dispatch_object_event.

Pointer-positioned events carry coordinates used for hit-test target resolution. Key and encoder events route to the focused node.

Variants§

§

Pointer

A pointer stream event to be delivered to the hit-test target.

The wrapped Event must be a pointer-positioned variant (PressDown, PressRelease, DoubleTap, LongPress, etc.). The x/y coordinates are used for hit testing.

Fields

§x: i32

Pointer horizontal coordinate for hit-test resolution.

§y: i32

Pointer vertical coordinate for hit-test resolution.

§event: Event

The stream event to translate into an ObjectEvent.

§

PointerObject

An ObjectEvent to deliver to the hit-test target at (x, y).

Fields

§x: i32

Pointer horizontal coordinate for hit-test resolution.

§y: i32

Pointer vertical coordinate for hit-test resolution.

§event: ObjectEvent

The object-semantic event to dispatch.

§

Focused

An ObjectEvent to deliver to the currently focused node.

Fields

§event: ObjectEvent

The object-semantic event to dispatch.

§

Container

An ObjectEvent targeted at the node identified by a structural path, bypassing hit-test resolution.

The event is delivered to that node’s target handlers, then bubbles through ancestors using the existing per-node ObjectFlags::EVENT_BUBBLE gating — identically to how any other event bubbles. The ObjectFlags::EVENT_BUBBLE flag is never mutated (LPAR-05 §6.3/§16).

Fields

§path: Vec<usize>

Structural path from root to the target node (list of child indices).

§event: ObjectEvent

The object-semantic event to dispatch.
