Variants§

§

Move

Fields

§pointer_id: PointerId
§position: Point
§modifiers: Modifiers
§pointer_type: PointerType
§

Down

Fields

§pointer_id: PointerId
§position: Point
§modifiers: Modifiers
§click_count: u8

Consecutive click count for this button (1 = single click, 2 = double click, …).

This count is provided by the platform runner and only increments for “true clicks” (press + release without exceeding a small drag threshold).

§pointer_type: PointerType
§

Up

Fields

§pointer_id: PointerId
§position: Point
§modifiers: Modifiers
§is_click: bool

Whether this pointer-up completes a “true click” (press + release without exceeding the runner’s click slop threshold).

This signal is computed by the platform runner and is intentionally separate from click_count: click_count can remain stable even when a press turns into a drag.

§click_count: u8

Consecutive click count for this button (1 = single click, 2 = double click, …).

See PointerEvent::Down.click_count for the normalization rules.

§pointer_type: PointerType
§

Wheel

Fields

§pointer_id: PointerId
§position: Point
§delta: Point
§modifiers: Modifiers
§pointer_type: PointerType
§

PinchGesture

Two-finger pinch gesture, typically produced by touchpads (and some touch platforms).

delta is positive for magnification (zoom in) and negative for shrinking (zoom out). This value may be NaN depending on the platform backend; callers should guard accordingly.

Fields

§pointer_id: PointerId
§position: Point
§delta: f32
§modifiers: Modifiers
§pointer_type: PointerType
