Struct TapEvent 

#[non_exhaustive]
pub struct TapEvent {
    pub position: Point,
    pub button: PointerButton,
    pub modifiers: Modifiers,
    pub pointer: PointerInfo,
}

Information about a recognized click-style gesture, passed to the four tap-family handlers (on_tap, on_double_tap, on_triple_tap, on_long_press).

The struct is #[non_exhaustive] so future fields (timestamp, click count for a hypothetical on_n_tap, pressure for stylus events) can land without breaking existing match patterns.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

position: Point

Pointer position in widget-local coords, captured at the finalising event (the Up of the last tap for tap / double-tap / triple-tap; the held Down for long-press, since long-press recognises on a tick before any Up).

button: PointerButton

Which button finalised the gesture. Multi-tap recognizers require every tap in the sequence to use the same button — mixed-button sequences fail rather than spuriously firing.

modifiers: Modifiers

Modifier keys held at the finalising event. Sourced from WidgetEvent::PointerUp { modifiers, .. } (or PointerDown for long-press).

pointer: PointerInfo

Which pointer produced the gesture — the mouse, a numbered finger, a stylus. A handler reads pointer.kind to tell a finger tap from a click without consulting the tree.

Implementations

impl TapEvent

pub fn new(position: Point, button: PointerButton, modifiers: Modifiers) -> Self

Construct a TapEvent directly. Useful for tests; widgets receive &TapEvent from the recognizer pipeline and rarely need to build one by hand.

pub fn with_pointer(self, pointer: PointerInfo) -> Self

The same event attributed to pointer. The recognizers build their TapEvents this way, from the pointer on the sample that finalised the gesture.
