FileView (Java Platform SE 8 ) (original) (raw)

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 toJFileChooser to return different icons or additional information using JFileChooser.setFileView(javax.swing.filechooser.FileView).

JFileChooser first looks to see if there is a user definedFileView, 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 seeHow to Use File Choosers, a section in The Java Tutorial.
