public class VemaxsFileFilter

extends FileFilter

A convenience implementation of FileFilter that filters out
all files except for those type extensions that it knows about.

Extensions are of the type ".foo", which is typically found on
Windows and Unix boxes, but not on Macinthosh. Case is ignored.

Example - create a new filter that filerts out all files
but gif and jpg image files:

JFileChooser chooser = new JFileChooser();
ExampleFileFilter filter = new ExampleFileFilter(
new String{"gif", "jpg"}, "JPEG & GIF Images")
chooser.addChoosableFileFilter(filter);
chooser.showOpenDialog(this);
