Using a FileDialog to choose a file of a certain extension

Question

I am trying to use a FileDialog file chooser because I really need java app to have the native apple file chooser (I know we all hate hate the lack of portability but this is what I need). I am trying to make my file chooser allow the user to pick files that end with .ws. Here is what I tried:

            FileDialog fd = new         

           FileDialog(_sharedInstance,rsc.str("480"),FileDialog.LOAD);
           // fd.setFile("*.ws");
            class WSFilter implements FilenameFilter {
                public boolean accept(File dir, String name) {
                    return (name.endsWith(".ws"));
                }
            };
            FilenameFilter wsFilter = new WSFilter();

            fd.setFilenameFilter(wsFilter);
            fd.setDirectory(_projectsBaseDir.getPath());
            fd.setLocation(50,50);

           // fd.setFile("*");
            fd.setVisible(true);

For some reason my file chooser won't allow me to pick any files. Any ideas?

Answer 1

Answer was I need this call: System.setProperty("apple.awt.fileDialogForDirectories", "false");

Answer 2

Why not use JFileChooser?

JFileChooser fileChooser = new JFileChooser(new File(filename));
fileChooser.addChoosableFileFilter(new MyFilter());

class MyFilter extends javax.swing.filechooser.FileFilter {
    public boolean accept(File file) {
        String filename = file.getName();
        return filename.endsWith(".java");
    }
    public String getDescription() {
        return "*.java";
    }
}

Haven't this been asked before?

Anyway, you may try to change L&F and keep using JFileChooser.

I've heard this one is good:
