     总是觉得Java Swing没有Android的好,不能自定义组件,实现漂亮的进度提示框,比如那种转圈的,谷歌了一下竟然发现有大牛实现了类似的额效果:


      使用方法:

1.具体只需要两个类:AnimatedPanel.java, InfiniteProgressPanel.java,具体的内容如下:

     AnimatedPanel.java的代码如下:

     3.如何在你的Java Swing使用呢,如下步骤:

JFrame frame = new JFrame(); // ... InfiniteProgressPanel glasspane = new InfiniteProgressPanel();
	Dimension dimension = Toolkit.getDefaultToolkit().getScreenSize(); 		glasspane.setBounds(100, 100, (dimension.width) / 2, (dimension.height) / 2); frame.setGlassPane(glasspane); glasspane.start();//开始动画加载效果 frame.setVisible(true);   // Later, to disable,在合适的地方关闭动画效果 glasspane.stop();
