我创建了一个新类,扩展了JFrame和扩展JPanel以创建swing GUI的新类.很棒,我喜欢这个,因为它易于阅读.

然而,当涉及到事件处理时,事情变得越来越复杂.我所做的确实不是一个解决方案; 就像打破好习惯,让事情发挥作用一样.我该如何正常工作？

这是我的JFrame类

public class MainFrame extends JFrame{
    private JTextArea textArea;

    public MainFrame(String title){
        super(title);

        //set layout
        setLayout(new BorderLayout());

        //create components
        JButton buttonOne = new JButton("click me");
        textArea = new JTextArea();
        JPanel detailedPanel = new leftPanel();

        //add to panel
        Container c = getContentPane();

        c.add(buttonOne, BorderLayout.SOUTH);
        c.add(textArea, BorderLayout.CENTER);
        c.add(detailedPanel, BorderLayout.WEST);

        //Event Listening
        leftPanel.buttonAdd.addActionListener(new ActionListener(){
            public void actionPerformed(ActionEvent e) {
                textArea.setText(textArea.getText() + " " + leftPanel.fieldName.getText() + " : " + leftPanel.fieldOccupation.getText());
            }

        });

    }

}

这是我的JPanel
