苹果风格的swing外观

首先去下载苹果风格的jar包。quaqua.jar 下载地址：https://quaqua.dev.java.net/

swing的界面通常是通过UIManager.setLookAndFeel来控制的。

设置UIManager的代码：

public static void main(String args[]){
		System.setProperty("Quaqua.tabLayoutPolicy", "wrap");

		if (!System.getProperty("os.name").toLowerCase().startsWith("mac")) {
			try {
				Methods.invokeStatic(JFrame.class,
						"setDefaultLookAndFeelDecorated", Boolean.TYPE,
						Boolean.TRUE);
				Methods.invokeStatic(JDialog.class,
						"setDefaultLookAndFeelDecorated", Boolean.TYPE,
						Boolean.TRUE);
			} catch (NoSuchMethodException e) {
				e.printStackTrace();
			}
		}
		try {			
			UIManager.setLookAndFeel("ch.randelshofer.quaqua.QuaquaLookAndFeel");
		} catch (Exception e) {
		}
		DBConnFrame f = new DBConnFrame();
		f.setTitle("数据库连接向导");
		f.setSize(600, 400);	
		f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);//关闭窗口事件
		f.setVisible(true);
	}

 就这样吧！看风格附图如下
