[cp-patches] FYI: MetalFileChooserUI

[David Gilbert]

I committed some more pieces of this class, it is still not usable, but I'm making 
good progress.  This patch shouldn't get in the way of anything and keeps the diffs 
between CVS and my working tree to a minimum:

2005-10-13  David Gilbert  <address@hidden>

        * javax/swing/plaf/metal/MetalFileChooserUI.java
        (DirectoryComboBoxAction): new inner class,
        (FileRenderer): new inner class,
        (directoryModel): new private field.

Regards,

Dave
