java.lang.Object javax.swing.filechooser.FileView
FileView defines an abstract class that can be implemented to provide the filechooser with
UI
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.
