PrimeNg TabView with ConfirmDialog

Question

I'm trying to use PrimeNg TabView component along with confirmDialog unsuccessfully, here is my code:

<p-tabView (onChange)="onTabChange($event)" [(activeIndex)]="index">...</p-tabView> 


  onTabChange(event){
    this.confirmationService.confirm({
      message: 'Do you confirm ?',
      accept:  () => {
      this.index = event.index;
      },
      reject:() =>{        }
      });
   }

Do you have an idea on how to prevent or allow tab change using confirm dialog ?

Thanks

Based on similar solution for material design tabs, here is the solution for my issue:

1. in html Declare a local variable referencing TabView DOM object:

<p-tabView #onglets>...</p-tabView>

2. in component.ts, change default function called when click on tab with specific function to match your case:

@ViewChild('onglets') onglets: TabView;
this.onglets.open = this.interceptOngletChange.bind(this);
...
interceptOngletChange(event: Event, tab: TabPanel){
  const result = confirm(`Do you really want to leave the tab?`);
  return result && TabView.prototype.open.apply(this.onglets, argumentsList);
});
