extends Object sample code for java.lang.Object definition code for java.lang.Object

FileView defines an abstract class that can be implemented to provide the filechooser with UI information for a File. Each L&F JFileChooserUI object implements this class to pass back the correct icons and type descriptions specific to that L&F. For example, the Microsoft Windows L&F returns the generic Windows icons for directories and generic files. Additionally, you may want to provide your own FileView to JFileChooser to return different icons or additional information using JFileChooser.setFileView(javax.swing.filechooser.FileView) sample code for javax.swing.JFileChooser.setFileView(javax.swing.filechooser.FileView) definition code for javax.swing.JFileChooser.setFileView(javax.swing.filechooser.FileView) .

JFileChooser first looks to see if there is a user defined FileView, if there is, it gets type information from there first. If FileView returns null for any method, JFileChooser then uses the L&F specific view to get the information. So, for example, if you provide a FileView class that returns an Icon for JPG files, and returns null icons for all other files, the UI's FileView will provide default icons for all other files.

For an example implementation of a simple file view, see yourJDK/demo/jfc/FileChooserDemo/ExampleFileView.java. For more information and examples see How to Use File Choosers, a section in The Java Tutorial.
