import java.awt.Image;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.awt.event.KeyEvent;
import java.awt.event.KeyListener;

/**

                     */
public class Main extends JFrame implements KeyListener, ActionListener{
public static JTextPane textPane;
/**
 * @param args the command line arguments
 */
public static void main(String[] args) {
    // TODO code application logic here
                JFrame Frame = new Main();
                Frame.setVisible(true);
                Frame.setSize(400, 400);





}
public Main()
{
    JMenuBar mb = new JMenuBar();
    setJMenuBar(mb);

    JMenu menu = new JMenu("File");
    JMenuItem mi = new JMenuItem("select all");
    mi.addActionListener(this);
    menu.setMnemonic(KeyEvent.VK_F);
    menu.add(mi);
    mi = new JMenuItem("copy");
    mi.addActionListener(this);
    menu.add(mi);
    mi = new JMenuItem("Exit");
    mi.addActionListener(this);
    menu.add(mi);
     mi = new JMenuItem("insert image");
    mi.addActionListener(this);
    menu.add(mi);
    mb.add(menu);
    textPane = new JTextPane();

    JScrollPane scrollPane = new JScrollPane(textPane);
    getContentPane().add(scrollPane);


}

public void keyTyped(KeyEvent e) {
    throw new UnsupportedOperationException("Not supported yet.");
}

public void keyPressed(KeyEvent e) {
    throw new UnsupportedOperationException("Not supported yet.");
}

public void keyReleased(KeyEvent e) {
    throw new UnsupportedOperationException("Not supported yet.");
}

public void actionPerformed(ActionEvent e) {
    String cmd=e.getActionCommand();
    if ("Exit".equals(cmd)) {
        System.exit(0);
    } else if ("select all".equals(cmd)) {
        textPane.selectAll();
    } 
    else if ("copy".equals(cmd)) {
      textPane.copy();

    }
    else if("insert image".equals(cmd))
    {
        try {
            JFileChooser file = new JFileChooser();
            file.showOpenDialog(null);
            File selFile = file.getSelectedFile();
            Image img = ImageIO.read(selFile);
            textPane.insertIcon(new ImageIcon(img));
        } catch (IOException ex) {
            Logger.getLogger(Main.class.getName()).log(Level.SEVERE, null, ex);
        }

    }
 }

}

推荐答案

我担心没有简单的方法可以做到这一点。
所有默认的EditorKits（StyledEditorKit，HTMLEditorKit，RTFEditorKit）都不支持图像复制。

I'm afraid there is no simple way to do this. All the default EditorKits (StyledEditorKit, HTMLEditorKit, RTFEditorKit) don't support images copying.

最接近的是HTMLEditorKit，但它会生成带有链接的HTML图片。

The closest one is HTMLEditorKit but it will generate HTML with links to images.
