public abstract class FileView extends Object
FileViewdefines an abstract class that can be implemented to provide the filechooser with UI information for aFile. Each L&FJFileChooserUIobject 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 ownFileViewtoJFileChooserto return different icons or additional information usingJFileChooser.setFileView(javax.swing.filechooser.FileView).JFileChooserfirst looks to see if there is a user definedFileView, if there is, it gets type information from there first. IfFileViewreturnsnullfor any method,JFileChooserthen uses the L&F specific view to get the information. So, for example, if you provide aFileViewclass that returns anIconfor JPG files, and returnsnullicons for all other files, the UI'sFileViewwill 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 see How to Use File Choosers, a section in The Java Tutorial.- See Also:
