Direct Known Subclasses:: BasicFileChooserUI.AcceptAllFileFilter

public abstract class FileFilter
extends Object

FileFilter is an abstract class that has no default implemention. A FileFilter, once implemented, can be set on a JFileChooser to keep unwanted files from appearing in the directory listing. A default implementation (ExtensionFileFilter) is currently in the FileChooserDemo directory, and will become a first class swing implementation in Swing 1.0.3. For an example implementation of a simple file filter, see yourJDK/demo/jfc/FileChooserDemo/ExampleFileFilter.java. For more information, see the Swing Connection article on the File Chooser
