How can I make a java FileDialog accept directories as its FileType in OS X?

Question

I am trying to switch from using a JFileChooser to a FileDialog when my app is being run on a mac so that it will use the OS X file chooser. So far I have the following cod

Assuming you're determined to use the FileDialog instead of the portable JFileChooser, you need to set the system property so that FileDialogs created are for directories.

The property in question is apple.awt.fileDialogForDirectories.

So simply do the following:

System.setProperty("apple.awt.fileDialogForDirectories", "true");
FileDialog fd = new FileDialog(this); 
fd.setDirectory(_projectsBaseDir.getPath()); 
fd.setLocation(50,50);
fd.setVisible(true); 
File selectedFile = new File(fd.getFile());
System.setProperty("apple.awt.fileDialogForDirectories", "false");

It should be noted that this isn't portable, however, since you're looking to replace the portable JFileDialog, I assume that's not an issue.
