EventElement Interface

Namespace:

@gembox/pdfviewer

Assembly:

@gembox/pdfviewer

An event-emitting interface that allows for type-safe event handling.

• TypeScript

export declare interface EventElement<TEventMap extends {
    [key: string]: any;
}>

Remarks

This interface provides a generic way to handle events with strongly-typed event data. It supports both synchronous and asynchronous event listeners, allowing for flexible event handling patterns.

Methods

addEventListener(K, (event: TEventMap[K]) => void)

Adds an event listener for the specified event type.

• TypeScript

addEventListener<K extends keyof TEventMap & string>(type: K, listener: (event: TEventMap[K]) => void): void;

Parameters

type

The event type/name to listen for.

listener

The callback function that will be invoked when the event is emitted.

Remarks

Multiple listeners can be registered for the same event type. The listener will be called with the strongly-typed event data when the event is emitted.
