Class XTFRFileFilter

  • public class XTFRFileFilter
extends javax.swing.filechooser.FileFilter
    This is taken from Sun's demo ExampleFileFiler.java 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(); XTFRFileFilter filter = new XTFRFileFilter( new String{"gif", "jpg"}, "JPEG & GIF Images") chooser.addChoosableFileFilter(filter); chooser.showOpenDialog(this);
