我想要这样的标签控件在此处输入图片说明

图片中恰好是我在C＃项目中使用的选项卡。这是componentone studio提供的具有许多自定义选项的组件。但是我找不到任何可以做这样的事情的Java插件。外观感觉一点也不好。谁能告诉我如何向我的应用程序添加时尚的标签控件。由于我是Java新手，请给我详细的答案。提前致谢。

它是选项卡式窗格，文档。

JTabbedPane 类。

页面的代码示例：

JTabbedPane tabbedPane = new JTabbedPane();
ImageIcon icon = createImageIcon("images/middle.gif");

JComponent panel1 = makeTextPanel("Panel #1");
tabbedPane.addTab("Tab 1", icon, panel1,
                  "Does nothing");
tabbedPane.setMnemonicAt(0, KeyEvent.VK_1);

JComponent panel2 = makeTextPanel("Panel #2");
tabbedPane.addTab("Tab 2", icon, panel2,
                  "Does twice as much nothing");
tabbedPane.setMnemonicAt(1, KeyEvent.VK_2);

JComponent panel3 = makeTextPanel("Panel #3");
tabbedPane.addTab("Tab 3", icon, panel3,
                  "Still does nothing");
tabbedPane.setMnemonicAt(2, KeyEvent.VK_3);

JComponent panel4 = makeTextPanel(
        "Panel #4 (has a preferred size of 410 x 50).");
panel4.setPreferredSize(new Dimension(410, 50));
tabbedPane.addTab("Tab 4", icon, panel4,
                      "Does nothing at all");
tabbedPane.setMnemonicAt(3, KeyEvent.VK_4);

protected JComponent makeTextPanel(String text) {
    JPanel panel = new JPanel(false);
    JLabel filler = new JLabel(text);
    filler.setHorizontalAlignment(JLabel.CENTER);
    panel.setLayout(new GridLayout(1, 1));
    panel.add(filler);
    return panel;
}

protected static ImageIcon createImageIcon(String path) {
    java.net.URL imgURL = TabbedPaneDemo.class.getResource(path);
    if (imgURL != null) {
        return new ImageIcon(imgURL);
    } else {
        System.err.println("Couldn't find file: " + path);
        return null;
    }
}
