Updated event

The NgScrollbar component has an output (updated) which emits when:

• After its view is initialised
• Any of its inputs change
• Resize sensor emitted (e.g. the content size is changed)

Example: Fire an event when the vertical scrollbar becomes scrollable (vertical scrollbar becomes visible)

<ng-scrollbar #scrollbar="ngScrollbar" (updated)="onScrollbarUpdate(scrollbar.state)"></ng-scrollbar>

onScrollbarUpdated(state: NgScrollbarState) {
  if (state.isVerticallyScrollable) {
    console.log('Scrollable');
  } else {
    console.log('Not Scrollable');
  }
}
