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 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 <A HREF="../../../javax/swing/JFileChooser.html#setFileView(javax.swing.filechooser.FileView)"><CODE>JFileChooser.setFileView(javax.swing.filechooser.FileView)</CODE></A>. <p> 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 <code>Icon</code> for JPG files, and returns <code>null</code> icons for all other files, the UI's FileView will provide default icons for all other files. <p> For an example implementation of a simple file filter, see <code><i>yourSDK</i>/demo/jfc/FileChooserDemo/ExampleFileView.java</code>.
