          (CreateNewTask)="createNewTask($event)"
          (LinkAction)="linkAction($event)"
          (LinkSelected)="linkSelected($event)"></gantt>

import {GanttComponent, GanttConfiguration, GanttTaskItem, GanttTaskLink,GanttEvents } from 'gantt-ui-component';


export myComponent {
    tasks = [
