How to add images icon in the title bar of JFrame?

Question

我需要在JFrame标题栏中添加图像，有人可以告诉我这样做的方法吗？

Answer 1

You could use Window#setImageIcons(List<Image>) which allows you to supply a series of different sized, which allows the underlying platform to choose a icon that is best suited to the platform and look and feel...

List<Image> images = new ArrayList<Image>(4);
images.add(ImageIO.read(getClass().getResource("/icons/icon16x16.png"));
images.add(ImageIO.read(getClass().getResource("/icons/icon24x24.png"));
images.add(ImageIO.read(getClass().getResource("/icons/icon32x32.png"));
images.add(ImageIO.read(getClass().getResource("/icons/icon48x48.png"));

frame.setImageIcons(images);

Answer 2

use frame.setIconImage(Image image) see http://docs.oracle.com/javase/6/docs/api/javax/swing/JFrame.html for details. Use BufferedImage to represent your image.
