public class PSFileView

extends javax.swing.filechooser.FileView

A convenience implementation of the FileView interface that manages name, icon, traversable, and file type information. This this implemention will work well with file systems that use "dot" extensions to indicate file type. For example: "picture.gif" as a gif image. If the java.io.File ever contains some of this information, such as file type, icon, and hidden file inforation, this implementation may become obsolete. At minimum, it should be rewritten at that time to use any new type information provided by java.io.File Example: JFileChooser chooser = new JFileChooser(); fileView = new ExampleFileView(); fileView.putIcon("jpg", new ImageIcon("images/jpgIcon.jpg")); fileView.putIcon("gif", new ImageIcon("images/gifIcon.gif")); chooser.setFileView(fileView); Modified for Powerflow by Frédéric Demers & Guillaume Gilbert on 21 Nov 98

getIcon

public javax.swing.Icon getIcon(java.io.File f)

isHidden

public java.lang.Boolean isHidden(java.io.File f)

isTraversable

public java.lang.Boolean isTraversable(java.io.File f)

Whether the directory is traversable or not. Generic implementation returns true for all directories. You might want to subtype ExampleFileView to do somethimg more interesting, such as recognize compound documents directories; in such a case you might return a special icon for the diretory that makes it look like a regular document, and return false for isTraversable to not allow users to descend into the directory.

Overrides:

isTraversable in class javax.swing.filechooser.FileView

See Also:

isTraversable(java.io.File)
