import { UIAbility } from '@kit.AbilityKit'; 
export default class EntryAbility extends UIAbility { 
  onForeground() { 
    this.context.eventHub.on('myEvent', this.eventFunc); 
    this.context.eventHub.emit('myEvent');
    this.context.eventHub.emit('myEvent', 1);
    this.context.eventHub.emit('myEvent', 1, 2); 
  }  
  eventFunc(argOne: number, argTwo: number) { 
    console.log('eventFunc is called, ${argOne}, ${argTwo}'); 
  } 
}
