java - 使用 Web 浏览器延迟 JOptionPane

Question

想知道如何延迟 JOptionPane。目标是先弹出图片，然后弹出框，以便该框始终在默认浏览器前面打开。

代码

            //this is with the bottom thing, probably above the modules
            public void openWebPage(String url){
                   try {         
                     java.awt.Desktop.getDesktop().browse(java.net.URI.create(url));
                   }
                   catch (java.io.IOException e) {
                       System.out.println(e.getMessage());
                   }
                }

            private void ResetButtonActionPerformed(ActionEvent e)
            {

                openWebPage("http://www.rd.com/wp-content/uploads/sites/2/2016/04/01-cat-wants-to-tell-you-laptop.jpg");

                 //int delay = 1000; //milliseconds [Unused]

                String message = "I didn't know how to code a reset button." + "\n";
                String message2 = "So have a nice cat instead. -Cakemoth";


                JOptionPane.showConfirmDialog(null, message + message2, "Class Registration", JOptionPane.DEFAULT_OPTION,
                JOptionPane.INFORMATION_MESSAGE);

                // URL : http://www.rd.com/wp-content/uploads/sites/2/2016/04/01-cat-wants-to-tell-you-laptop.jpg
            }

为什么要尝试在浏览器中显示图像？

只需在 JLabel 中显示图像并将标签添加到框架中即可。然后您就可以完全控制该应用程序。

您可以使用 ImageIO 从 URL 读取图像:

BufferedImage image = Imagio.read(...);
ImageIcon icon = new ImageIcon( image );
JLabel label = new JLabel( icon );
frame.add( label );
frame.setVisible( true );

// show JOptionPane
