fileChooser question

I was wondering if there was a way to setup the file chooser so that
directories can be selected but also so that navigation was impossible.

I was the user to pick a sub directory of a given directory. However,
if I enable directories, then the user can change the directory.

fileChooser.setFileSelectionMode(fileChooser.DIRECTORIES_ONLY);
fileChooser.setDialogTitle("Select Directory");
fileChooser.resetChoosableFileFilters();
fileChooser.setAcceptAllFileFilterUsed(false);
fileChooser.setFileFilter(filter);
fileChooser.setCurrentDirectory( rootDir );

filter is a filter that just returns true for directories.

I haven't done this, but I would start by implementing an own FileView,
where isTraversable() returns false for the particular directories, and
all other methods return null (which delegates the JFileChooser to the
default FileView). Then I would set the new FileView as the FileView for
the JFileChooser.

I guess you could provide a FileSystemView that always returns false for
isTraversable. Or a FileView that returns Files that always claim to be
not directories (that might mess up the icon, for instance).
