Here's my code:
String s = "/Applications/Asphalt6.app"; JFileChooser chooser = new JFileChooser(); File file = new File(s); Icon icon = chooser.getIcon(file); // show the icon JLabel ficon = new JLabel(s, icon, SwingConstants.LEFT);
Now, the image extracted from the icon is really small. How can I resize it?
