  templateUrl: "./app.component.html",
  styleUrls: ["./app.component.scss"]
})
export class AppComponent implements OnInit {
  title = "border-tester";
  private _coordinateService: PublicAPI.CoordinateComponent;

  constructor(private _ref: ElementRef) {}

  ngOnInit() {
    this._coordinateService = new PublicAPI.CoordinateComponent(
      document.querySelector('.container')
    );
  }

  onBorder($event) {
    console.log("on Border", $event.target, 'onBorder', this._coordinateService.onBorder());
    console.log ("onDragStartTest", this._coordinateService.onDragStart());
  }

  onMouseOver($event) {
    console.log("on Border", $event.target, 'onBorder', this._coordinateService.onBorder());
    console.log ("onDragStartTest", this._coordinateService.onDragStart());
  }
