действие при изменении состояния компонента

Question

У меня есть серия переключателей, сгенерированных в виде массива и отображаемых в jPanel.

Я хочу, чтобы ряд флажков во второй панели был включен, когда переключатели находятся в выходном состоянии, но не на входе (вход или выход - это выбор радио).

Я хочу вызвать метод проверки, когда какое-либо из состояний радиообмена изменяется, но не знает, как это сделать, поскольку они созданы в массиве.

В настоящее время метод вызывается только при нажатии кнопки переключателя.

Answer 1

digitalPinRadioButtonArray[x][y].addActionListener(new ActionListener() { 

       @Override 
       public void actionPerformed(ActionEvent e) { 
        // TODO Auto-generated method stub 
        if(e.getActionCommand().equals("Output")) 
          { 
            digitalPinOutputArray[2].setSelected(true); 
          } 

       } 
      });
