java - JFileChooser select directory but show files

Question

I feel like there should be a simple way to do this but I can't figure it out. I have a JFileChooser that allows the user to select directories. I want to show all the files in the directories to give the user some context, but only directories should be accepted as selections (maybe the Open button would be disabled when a file is selected). Is there an easy way of doing this?

My solution is a merge between the answers of camickr and trashgod:

    final JFileChooser chooser = new JFileChooser() {
            public void approveSelection() {
                if (getSelectedFile().isFile()) {
                    return;
                } else
                    super.approveSelection();
            }
    };
    chooser.setFileSelectionMode( JFileChooser.FILES_AND_DIRECTORIES );
