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:

package com.jframe.ceshi;

import java.awt.AlphaComposite;

 */





public class AnimatedPanel extends JPanel {





 





	/**

	public AnimatedPanel(String message, ImageIcon icon) {





		this.message = message;





		this.font = getFont().deriveFont(14.0f);

				Rectangle2D bounds = layout.getBounds();





 





				int x = (width - convolvedImage.getWidth(null)) / 2;

			}





		}





	}

	@Override





	public void mouseClicked(MouseEvent e) {





	}





 





	@Override





	public void mousePressed(MouseEvent e) {





	}





 





	@Override





	public void mouseReleased(MouseEvent e) {





	}





 





	@Override





	public void mouseEntered(MouseEvent e) {





	}





 





	@Override





	public void mouseExited(MouseEvent e) {





	}

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();
