유형 ENTER 키가 캡처되지 않습니다.

Question

제 애플리케이션에서 Key 이벤트를 매핑 한 JTable이 있습니다. 출처 :

getInputMap(JComponent.WHEN_ANCESTOR_OF_FOCUSED_COMPONENT).put(KeyStroke.getKeyStroke(KeyEvent.VK_ENTER, 0), "selectNextColumnCell"); 
    getActionMap().put("selectNextColumnCell", new AbstractAction() { 

     @Override 
     public void actionPerformed(ActionEvent e) { 
      //DO SOMETHING 
     } 
    }); 

} 

하지만이 작업은 내가 Enter 키를 눌렀을 때만 호출되고 해제되지 않습니다. 하지만 사용자가 엔터 키를 입력 할 때마다이 작업을 호출해야합니다.

예를 들어 put(KeyStroke.getKeyStroke(KeyEvent.VK_ENTER....
