向JComboBox添加JTextPane字符串

JTextPane textPane = new JTextPane();
textPane.setText("Hello, World!");

DefaultComboBoxModel<String> comboBoxModel = new DefaultComboBoxModel<>();

comboBoxModel.addElement(textPane.getText());

JComboBox<String> comboBox = new JComboBox<>(comboBoxModel);

import javax.swing.DefaultComboBoxModel;
import javax.swing.JComboBox;
import javax.swing.JFrame;
import javax.swing.JTextPane;

public class ComboBoxExample extends JFrame {
    public ComboBoxExample() {
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        setTitle("JComboBox Example");

        JTextPane textPane = new JTextPane();
        textPane.setText("Hello, World!");

        DefaultComboBoxModel<String> comboBoxModel = new DefaultComboBoxModel<>();
        comboBoxModel.addElement(textPane.getText());

        JComboBox<String> comboBox = new JComboBox<>(comboBoxModel);

        add(comboBox);

        pack();
        setVisible(true);
    }

    public static void main(String[] args) {
        new ComboBoxExample();
    }
}
