Blocks can emit events. When the LeadArt component is functioning as a Gallery, it will emit events for when the next or previous image is viewed.

If you want to listen to these events, the first thing is to import the EventEmitter object into your code:

import { EventEmitter } from '@wpmedia/engine-theme-sdk'

Then create a callback function such as:

const myGalleryImageNext = (event) => {console.log('Here is the event: ', event);}
const myGalleryImagePrevious = (event) => {console.log('Here is the event: ', event);}

Then use you use your callback in subscribing to the event:

EventEmitter.subscribe('galleryImageNext', (event) => myGalleryImageNext(event)); EventEmitter.subscribe('galleryImagePrevious', (event) => myGalleryImagePrevious(event));

The event object for these events will contain the following information:

eventName (String): The event name fired. In this case could be either galleryImageNext or galleryImagePrevious.
ansGalleryId (String): The id of the gallery.
ansGalleryHeadline (String): The headline for the gallery.
ansImageId (String): The id for the current image.
caption (String): The caption for the current image.
orderPosition (Number): The position in the carousel for the current image.
totalImages (Number): Total number of images in the carousel.
autoplay (boolean): whether or not the event triggered during autoplay. Value is either true or false.

This is optional. Please add an additional context that would be important to know in order to use this block.
