com.oorian.messaging.events.client.ClientEvent<PointerListener>
com.oorian.messaging.events.client.PointerEvent
Direct Known Subclasses:
PointerCancelEvent, PointerDownEvent, PointerEnterEvent, PointerLeaveEvent, PointerMoveEvent, PointerOutEvent, PointerOverEvent, PointerUpEvent
public abstract class PointerEvent extends ClientEvent<PointerListener>
Abstract base class for all pointer-related events in the client interface.

Pointer events unify mouse, pen, and touch input into a single event model. This class serves as the foundation for specific pointer event types, providing common fields for tracking pointer coordinates, pointer identity, pointer type, contact geometry, pressure, tilt, and whether the pointer is the primary pointer.

Features:

  • Provides coordinate and pointer identity tracking for all pointer events
  • Captures contact geometry (width, height) and pressure
  • Captures tilt angles for pen/stylus input
  • Identifies pointer type (mouse, pen, touch)
  • Integrates with the PointerListener interface
