JPanel을 드래그 가능하게 만들기

Question

JPanel (이미지 참조)을 사용하여 Mac에서 툴바를 확장했지만 실제로 툴바 인 부분 (JPanel이 아님) 만 클릭하고 끌 수 있습니다. 툴바처럼 JPanel을 클릭하고 드래그하여 창을 이동할 수있게하는 방법

이미지의 상단 ㎜ 정도가 실제 툴바 (텍스트 포함)이고 나머지는 JPanel입니다. (버튼 포함).

가 어떻게 이동하는 JPanel의를 클릭하고 드래그하여 사용자를 허용 않습니다 여기

는 JFrame의 국경 레이아웃의 북쪽에 설정되어 UnifiedToolPanel, 코드입니다

private int x; 
    private int y; 
    //..... 
    //On mouse pressed: 
    jpanel.addMouseListener(new MouseAdapter(){ 
     public void mousePressed(MouseEvent ev){ 
     x = ev.getX(); 
     y = ev.getY(); 
     } 
    }); 
    //.... 
    //on mouse dragged 
    jpanel.addMouseMotionListener(new MouseMotionAdapter() { 
       public void mouseDragged(MouseEvent evt) { 
        int x = evt.getXOnScreen()-this.x; 
        int y = evt.getYOnScreen -this.y; 
        this.setLocation(x,y); 

       } 
      }); 

this.setLocation(x,y)가 프레임을 이동합니다 : 창 여기
는 방법입니다패널이이 아니므로 클래스가 JFrame으로 확장되었다고 생각합니다.
그러나 점 (x, y)을 반환하는 메서드를 만들고 창으로 설정할 수 있습니다.
