Type alias tListenerCallback

Type declaration

• • (pEvent: InfiniteEvent, pCallbackData: Object | undefined): void

    When event are fired, registered callbacks are called. Callbacks are installed on objects implementing the EventDispatcherInterface.

    /** 
     * Sample to illustrate how to use the 3djuump infinite signal system.
     */
    import { FilterItemInterface, FilterItemInterfaceSignal } from 'generated/documentation/appinfiniteapi';
    
    // filter has been created previously
    let lFilter : FilterItemInterface;
    
    // we want to be notified when events occur
    const lCallbackId : string = lFilter.addEventListener(FilterItemInterfaceSignal.FilterChanged, (_event: any, _pObject: Object | undefined) =>
    {
        // output a fancy message when filter changes
        console.log('filter has changed');
        // and remove the listener
        lFilter.removeEventListenerById(lCallbackId);
    });
    
    

    
    The syntax is very close to the DOM addEventlistener functions.
