问题描述

我想创建自己的文件，其图标继承自JFrame图标，我设置它，在java和我自己的文件中使用FileOutputStream和ObjectOutputStream

I want to create my own file with icon that inherit from JFrame icon, that I set it, in java and my own file use FileOutputStream and ObjectOutputStream

try {
    ObjectOutputStream oos;
    //I create own file with own extension in drive D:
    FileOutputStream fos = new FileOutputStream("D:/myFile.ckl");
    oos = new ObjectOutputStream(fos);
    //Write Document in JTextPane to File
    oos.writeObject(jTextPane.getStyledDocument());
    oos.close();
    fos.close();
} catch (Exception exp) {
    JOptionPane.showMessageDialog(null, "" + exp.getStackTrace());
}

提前谢谢

推荐答案

@David是正确的，主机平台拥有 JFrame 装饰，但你可以利用 JInternalFrame 图标，通常概括了平台的图标。例如，

@David is correct that the host platform owns the JFrame decorations, but you may be able to leverage the JInternalFrame icons, which typically recapitulate those of the platform. For example,

private static final Icon ICON = (Icon) UIManager.get("InternalFrame.closeIcon");

枚举其他装饰默认值这里。

/** @see http://stackoverflow.com/a/10360374/230513 */
public class InternalFrameIcons extends JPanel {

    public InternalFrameIcons() {
        this.setLayout(new GridLayout(0, 1, 5, 5));
        this.setBorder(BorderFactory.createEmptyBorder(5, 5, 5, 5));
        this.add(createLabel("InternalFrame.closeIcon"));
        this.add(createLabel("InternalFrame.maximizeIcon"));
        this.add(createLabel("InternalFrame.minimizeIcon"));
    }

    private JLabel createLabel(String name) {
        Icon icon = (Icon) UIManager.get(name);
        JLabel label = new JLabel(name, icon, JLabel.CENTER);
        label.setHorizontalTextPosition(JLabel.CENTER);
        label.setVerticalTextPosition(JLabel.BOTTOM);
        return label;
    }

    private void display() {
        JFrame f = new JFrame("InternalFrameIcons");
        f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
        f.add(this);
        f.pack();
        f.setLocationRelativeTo(null);
        f.setVisible(true);
    }

    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {

            @Override
            public void run() {
                new InternalFrameIcons().display();
            }
        });
    }
}
