Treeview 클래스

public class TreeView : ItemsControl<TreeViewItemDataBindingArgs>

ItemsControl의 인터페이스를 상속

간단하게 

EventHandler를 추가하기 위해

EventArgs를 상속받는 클래스를 하나 선언(ShowUIArgs)

  public class ShowUIArgs : EventArgs

    {

        private object[] v;

        private PointerEventData eventData;

        public ShowUIArgs(object[] v, PointerEventData eventData)

        {

            this.v = v;

            this.eventData = eventData;

        }

    }

EventHandler 하나 선언

public event EventHandler<ShowUIArgs> ShowUI;///20210415 우클릭 신규 추가 이벤트

EventHandler를 콜하는 함수 설정
