如何禁用一个按钮而不是Java Swing中的全部按钮？

Question

I have one actionListener attached to all my Buttons. I have 26 buttons each corresponding to one alphabet. After an alphabet is clicked, I want to disable that button alone. how can I achieve this Jwing? I am pasting a part of code, as my entire is too long and has other details which are not necessary. Thanks

public DetailsPanel(GuessPane guess) {
            setLayout(new BorderLayout());
            setBorder(BorderFactory.createTitledBorder(" click here "));

            JPanel letterPanel = new JPanel(new GridLayout(0, 5));
            for (char alphabet = 'A'; alphabet <= 'Z'; alphabet++) {
                String buttonText = String.valueOf(alphabet);
                JButton letterButton = new JButton(buttonText);
                letterButton.addActionListener(clickedbutton(guess));
                letterPanel.add(letterButton, BorderLayout.CENTER);
            }
            add(letterPanel, BorderLayout.CENTER);
        }

        private ActionListener clickedbutton(final GuessPane guess) {
            return new ActionListener() {
                public void actionPerformed(ActionEvent e) {
                    JButton pressedButton = (JButton) e.getSource();
                    String actionCommand = e.getActionCommand();
                    try {
                        System.out.println("actionCommand is: ---" + actionCommand);
                        guess.setLetter(actionCommand);
                    } catch (ParseException e1) {
                        // TODO Auto-generated catch block
                        e1.printStackTrace();
                    }

您可以使用event.getSource()获取事件的来源（ notice getSource()返回一个Object因此您也需要对其进行强制转换）：

((AbstractButton)event.getSource()).setEnabled(false);
