Fields

id: BlitzPointerId

is_primary: bool

coords: PointerCoords

button: MouseEventButton

buttons: MouseEventButtons

mods: Modifiers

details: PointerDetails

element: Point<f32>

active_pointers: Arc<AtomicRefCell<Vec<BlitzPointerEvent>>>

All pointers that are currently active (pressed) on the surface, including the one that triggered this event.

This is shared via Arc so that it can be cheaply cloned into each dispatched event and cheaply mutated as pointers are pressed, moved and released. It is primarily used to populate the touches list of touch events (multi-touch support).

The events stored in this list always have an empty active_pointers list themselves, to avoid a reference cycle.

Implementations

impl BlitzPointerEvent

pub fn at(x: f32, y: f32, buttons: MouseEventButtons) -> BlitzPointerEvent

A synthetic primary-mouse event at a viewport coordinate.

For callers driving a document programmatically (a test, a debug control surface, an agent) rather than translating a real device event. The twelve-field literal this replaces is currently hand-rolled in blitz-shell, blitz-script and dioxus-native-dom, each with its own idea of the defaults.

screen, page and client all take the same value: a synthetic event has no window offset or scroll origin to distinguish them. element is left at the origin because the offset within the target is only known after hit-testing, which the document does when the event is dispatched.
