Re: Preventing Package selection in JFileChooser

Donald Leeper wrote:

Is there a way (without JNI) to get JFileChooser to display
directories as not grayed out (traversable) and yet not allow the
selection of Packages? (I can filter on .app files to prevent
selecting Applications but is there a way to deal with Packages
generally?)

I use the method JFileChooser.isTraversable(File) in a file filter. There is a FileSystemView.isTraversable, but it returns TRUE for packages and non-package directories alike. Since JFileChooser.isTraversable(File) is not static, the file filter needs a reference back to the originating JFileChooser (well, it need not be the originating JFileChooser, I had to hack a couple of places where the original JFileChooser was not readily available, and using an arbitrary "new JFileChooser()" also works).
