How do I restrict JFileChooser to a directory?

Question

I want to limit my users to a directory and its sub directories but the "Parent Directory" button allows them to browse to an arbitrary directory.

How should I go about doing that?

Answer 1

Incase anyone else needs this in the future:

class DirectoryRestrictedFileSystemView extends FileSystemView {     private final File[] rootDirectories;      DirectoryRestrictedFileSystemView(File rootDirectory)     {         this.rootDirectories = new File[] {rootDirectory};     }      DirectoryRestrictedFileSystemView(File[] rootDirectories)     {         this.rootDirectories = rootDirectories;     }      @Override     public File createNewFolder(File containingDir) throws IOException     {                throw new UnsupportedOperationException("Unable to create directory");     }      @Override     public File[] getRoots()     {         return rootDirectories;     }      @Override     public boolean isRoot(File file)     {         for (File root : rootDirectories) {             if (root.equals(file)) {                 return true;             }         }         return false;     } } 

You'll obviously need to make a better "createNewFolder" method, but this does restrict the user to one of more directories.

And use it like this:

FileSystemView fsv = new DirectoryRestrictedFileSystemView(new File("X:\\")); JFileChooser fileChooser = new JFileChooser(fsv); 

or like this:

FileSystemView fsv = new DirectoryRestrictedFileSystemView( new File[] {     new File("X:\\"),     new File("Y:\\") }); JFileChooser fileChooser = new JFileChooser(fsv);

You can probably do this by setting your own FileSystemView.
