ExtensionFileFilter

java.lang.Object
- javax.swing.filechooser.FileFilter
- - diva.gui.ExtensionFileFilter

All Implemented Interfaces:

java.io.FilenameFilter

Direct Known Subclasses:

TableauFrame.ExtensionFileFilter

Deprecated.
Use ptolemy.gui.ExtensionFilenameFilter because it can be used with PtFileChooser
```
@Deprecated
public class ExtensionFileFilter
extends javax.swing.filechooser.FileFilter
implements java.io.FilenameFilter
```
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 Macintosh. Case is ignored.
Extension - create a new filter that filters out all files but gif and jpg image files:
```
     JFileChooser chooser = new JFileChooser();
     ExtensionFileFilter filter = new ExtensionFileFilter(
                   new String{"gif", "jpg"}, "JPEG & GIF Images")
     chooser.addChoosableFileFilter(filter);
     chooser.showOpenDialog(this);
 
```
Note that as of Java 1.6, there is a FileNameExtensionFilter which replaces this class. See http://download.oracle.com/javase/6/docs/api/javax/swing/filechooser/FileNameExtensionFilter.html However, this class can be used with both java.awt.FileDialog and javax.swing.JFileChooser because it implements java.io.FilenameFilter and extends javax.swing.FilenameFilter.
