javax.swing.filechooser.FileView
- Direct Known Subclasses:
- BasicFileChooserUI.BasicFileView
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).
 
 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.
