| 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
javax.swing.JFileChooser.setFileView .
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.
