Handlerable

Handlerable is the interaction-handler management mixin factory of maptalks. It lets a host class (such as Map) register, remove, and reuse multiple Handler subclasses. The host class binds a handler to a name via addHandler and unbinds it via removeHandler, enabling pluggable interaction management.

import { Class, Handler, Handlerable } from "maptalks";

const MapWithHandlers = Class.extend({ /* ... */ }).include(Handlerable).include({
  onAdd() {
    this.addHandler("drag", DragHandler);
  }
});

Constructor

Mixin factory — no independent constructor. The host class gains handler-management ability automatically after construction.

options

No independent configuration options.
