Stop image icon from caching.

I am trying to make the imageicon on some jLabels change dynamically when the image file changes but it seems like Java is caching the images and thus it wont work. Is there a way to disable the caching?

You can use the ImageIO class to read a fresh copy of the image.

Is this an applet? The applet plugin itself does caching.

Otherwise, don't use the version of ImageIcon that takes a path string

as an argument, because it callsToolkit's getImage, which caches.

Instead use the ImageIcon constructor that takes an image, and use

ImageIO to read that image.

But the Imageio read in a buffered image and the seticon method needs an image.

Huh?

BufferedImage bi = ImageIO.read(url_or_file_etc);

Icon icon = new ImageIcon(bi);

label.setIcon(icon);

BufferedImage is a subclass of Image, natch.
