Chapter 191: Draggable.addEventListener()

Core Idea

Registers a callback for a Draggable event type; inside the listener, this refers to the Draggable instance that fired it.

Reference Tables

Event	Fires when
press, click	pointer pressed / released as a click
dragstart, drag, dragend	drag lifecycle
release	pointer released (drag or not)
throwcomplete, throwupdate	inertia throw lifecycle (with InertiaPlugin)

Key Takeaways

1. Prefer passing callbacks directly in the Draggable vars (onDrag, onDragEnd, etc.) for the common case; use addEventListener when attaching listeners dynamically after creation.

Connects To

• Draggable.create(): where onDrag/onDragEnd/etc. vars-based callbacks are set instead.
