Java Basic : day 14 - AWT & SWING 8 : 마우스리스너

마우스리스너 MouseLisner

 

 

- MouseListener 인터페이스를 상속받으면 마우스 속성을 제어하고 설정할 수 있다.

 

 

* 상속 시 오버라이딩 메소드

-  e.getX(); ---> X 좌표의 값

-  e.getY(); ---> Y 좌표의 값

 

 

// 마우스 클릭 했을 때
@Override
public void mousePressed(MouseEvent e) {
         x = e.getX();
         y = e.getY();

         label.setText("x = " + x +", y = " + y);
}

@Override
public void mouseReleased(MouseEvent e) {

}
@Override
public void mouseEntered(MouseEvent e) {

}

@Override
public void mouseExited(MouseEvent e) {
// TODO Auto-generated method stub

}

 

// 마우스 드래그 할때
@Override
public void mouseDragged(MouseEvent e) {

         x = e.getX();
         y = e.getY();

         label.setText("x = " + x +", y = " + y);
}

@Override
public void mouseMoved(MouseEvent e) {

            label.setText("x = " + e.getX() +", y = " +  e.getY());

            // 레이블이 마우스를 따라다니도록 만들기
            label.setBounds(x, y, 200, 50);
}
